        * src/stand_alone/eth_drv.c: 
        * src/net/eth_drv.c: Improve network speeds by reducing some
        overhead and also the delay when sending a packet.

        we see an out-of-mbufs problem.

2003-03-11  Mark Salter  <msalter@redhat.com>

        * src/stand_alone/eth_drv.c (eth_drv_stop): Uncomment, make non-static,
        and use __local_enet_sc.
        * include/eth_drv.h: Add extern decl for eth_drv_stop.

2003-02-24  Jonathan Larmour  <jifl@eCosCentric.com>

        * cdl/eth_drivers.cdl: Add doc link.

        only a warning.

2002-08-14  Gary Thomas  <gthomas@ecoscentric.com>

        * cdl/eth_drivers.cdl: CYGNUM_IO_ETH_DRIVERS_SG_LIST_SIZE 
        needs to be global (used by all drivers, not just NET).

2002-08-13  Gary Thomas  <gthomas@ecoscentric.com>

        * src/net/eth_drv.c (eth_drv_send): Print a better message
        if the scatter-gather list overflows.

        * include/eth_drv.h (MAX_ETH_DRV_SG): 
        * cdl/eth_drivers.cdl: Add control over size of scatter-gather
        data lists used to pass requests to physical layer.  Previous
        value was sometimes too small.

2002-07-31  Gary Thomas  <gary@chez-thomas.org>

        * src/net/eth_drv.c (eth_drv_start): Fix compile error when
        built with old stack (no multicast) - introduced below.

2002-07-26  Gary Thomas  <gary@chez-thomas.org>
2002-07-26  Ken Cox <jkc@redhat.com>

        * src/net/eth_drv.c (eth_drv_start): Force multicast address
        setup any time chip is reset/reconfigured.

2002-05-30  Jonathan Larmour  <jlarmour@redhat.com>

        * cdl/eth_drivers.cdl: Provide CYGINT_IO_ETH_INT_SUPPORT_REQUIRED
        interface to indicate if interrupt support is required.

2002-05-28  Jonathan Larmour  <jlarmour@redhat.com>

        * src/lwip/lw.diff: Remove. Obsolete.

2002-05-13  Jesper Skov  <jskov@redhat.com>

        * cdl/eth_drivers.cdl: Moved the package's header files to
        cyg/io/eth to clean up the include root directory.

2002-04-30  Jonathan Larmour  <jlarmour@redhat.com>

        * src/lwip/eth_drv.c: Update from Jani Monoses.

        * cdl/eth_drivers.cdl: Move CYGINT_ISO_STRING_STRFUNCS requirement
        into CYGPKG_IO_ETH_DRIVERS_NET where it belongs.
        Move CYGINT_ISO_STRING_MEMFUNCS requirement into
        CYGPKG_IO_ETH_DRIVERS_STAND_ALONE where it belongs.

2002-04-10   Gary Thomas <gthomas@redhat.com>

        * src/net/eth_drv.c: Only pass mutlicast addresses down to drivers.     

2002-04-05   Jani Monoses  <jani@iv.ro>

        * src/lwip/eth_drv.c: New file. Add eth driver support for lwip.
        * src/lwip/lw.diff: New file. diff against lwip sources.
        * src/lwip/README: New file.
        * cdl/eth_drivers.cdl: Add lwip driver support.

2002-03-09  Gary Thomas  <gthomas@redhat.com>

        * src/net/eth_drv.c: Select 'multicast_all' if too many addresses
        are required.  Also, ignore any non-multicast addresses.

2002-02-22  Hugo Tyson  <hmt@redhat.com>

        * doc/ethdrv.sgml: New file.  SGML-ized the existing driver-doc
        file and brought the information up to date with deliver functions
        and all that.

2002-02-18  Gary Thomas  <gthomas@redhat.com>

        * cdl/eth_drivers.cdl: 
        Add new interface CYGINT_IO_ETH_MULTICAST which is used to
        insure that drivers support multicast addresses if IPv6 is used.

2002-02-15  Gary Thomas  <gthomas@redhat.com>

        * src/net/eth_drv.c: 
        * include/eth_drv.h: Add framework for multicast address support.

2002-01-30  Hugo Tyson  <hmt@redhat.com>

        * cdl/eth_drivers.cdl (CYGPKG_IO_ETH_DRIVERS_WARN_FORCE_CONSOLE):
        CDL options removed; control is now from RedBoot.

        * src/net/eth_drv.c (START_CONSOLE): Changed to use RedBoot
        fconfig items for deciding what console to use for special debug
        messages such as "out of MBUFs" and the like.

        * src/stand_alone/eth_drv.c (LOCK_APPLICATION_SCHEDULER): New
        macro to do what it says, before passing packets to the app.
        Used in two places: when passing a received packet, and when
        passing a tx completion status back.

2002-01-28  Gary Thomas  <gthomas@redhat.com>

        * src/net/eth_drv.c (eth_drv_init): Changes for supporting new
        FreeBSD based stack (minor API changes internal to that stack).

2001-12-12  Hugo Tyson  <hmt@redhat.com>

        * src/net/eth_drv.c (START_CONSOLE,END_CONSOLE): New macros akin
        to those within RedBoot's internal net_io.c, for directing warning
        messages to a serial line if required.  All printf's wrapped in
        them for safety.

        * cdl/eth_drivers.cdl (CYGPKG_IO_ETH_DRIVERS_WARN_FORCE_CONSOLE):
        and ..._NUMBER, new options to direct application warning output
        somewhere useful (less harmful) for when you are debugging over
        the net.  Trying to print within a call which occurred from within
        RedBoot itself is such a recursive situation as to be fatal.
        Defaults are disabled, you must choose to set these up if
        you want to debug your app safely over the network.

2001-12-12  Hugo Tyson  <hmt@redhat.com>

        * src/stand_alone/eth_drv.c (DIAG_DUMP_BUF_HDR,DIAG_DUMP_BUF_BDY):
        Separate macros for debug dumps of ethernet header and body.
        (eth_drv_write): Use them.
        (eth_drv_copy_recv): Do not corrupt the static data pointer, so
        that if we are erroneously called twice, at least what we pass is
        a packet, rather than random memory; do not escape to SEGV.  Guard
        against NULL sg_list[].buf pointers, in case caller out of MBUFs.
        (eth_drv_recv): Only dump packet if we actually have a buffer.
        Only forward the packet if actually have a buffer.

2001-12-04  Richard Sandiford  <rsandifo@redhat.com>

        * src/stand_alone/eth_drv.c (eth_drv_read): Check that the return
        buffer is big enough to hold the packet.

2001-11-28  Jonathan Larmour  <jlarmour@redhat.com>

        * doc/driver_doc: Mention preferences on how the ESA should be set.

2001-10-30  Jonathan Larmour  <jlarmour@redhat.com>

        * doc/driver_doc: Add description of poll, deliver and int_vector
        driver functions.

2001-10-29  Hugo Tyson  <hmt@redhat.com>

        * src/net/eth_drv.c (eth_drv_tickle_devices): [CASE 106613] Rather
        than calling can_send() in the device driver directly, call our
        own eth_drv_send() function which will also dequeue a waiting
        packet if we find we indeed can_send().  This helps to recover
        from queue full situations within the if_ethersubr layer above.
        This change is belt & braces with a similar call in the code which
        drops a packet if the queue is full, in the main network code in
        net/tcpip/.../src/sys/net/if_ethersubr.c (ether_output); this
        change will recover the situation shortly even if the application
        gives up trying to send because of ENOBUFS.

2001-10-18  Jonathan Larmour  <jlarmour@redhat.com>

        * cdl/eth_drivers.cdl: Rename CYGSEM_IO_ETH_DRIVERS_DEBUG to
        CYGDBG_IO_ETH_DRIVERS_DEBUG and make it a common option.
        Add separate CYGDBG_IO_ETH_DRIVERS_DEBUG_VERBOSITY config.

        * include/eth_drv.h: Don't claim BSD if it isn't.
        * include/eth_drv_stats.h: Ditto.
        * include/netdev.h: Ditto.
        * src/net/eth_drv.c: Ditto.
        Also use above CDL options to conditionalize debugging (and the
        verbosity level).
        * src/stand_alone/eth_drv.c: Use above renamed CDL options.

2001-10-11  Gary Thomas  <gthomas@redhat.com>

        * src/stand_alone/eth_drv.c (eth_drv_recv): 
        Defensive programming - insure valid packet size.

2001-10-05  Jonathan Larmour  <jlarmour@redhat.com>

        * src/net/eth_drv.c: Add default implementation of min().

2001-09-26  Jesper Skov  <jskov@redhat.com>

        * cdl/eth_drivers.cdl: Require the string functions.

        * src/stand_alone/eth_drv.c: Fix warnings.

2001-09-25  Hugo Tyson  <hmt@redhat.com>

        * src/net/eth_drv.c (eth_drv_dsr): Assert that the "sc" given to
        eth_drv_dsr() really is a sc from the valid list.  This can save a
        few hours debug time of a typo.

2001-09-13  Hugo Tyson  <hmt@redhat.com>

        * src/net/eth_drv.c (eth_drv_tickle_devices): New function to call
        can_send() on all devices to allow them to unstick from a lost
        interrupt or other wedge - it's up to the device to detect this,
        of course, can_send() does not explicitly do this, it's just used
        as an opportunity harmlessly to get control into the device so it
        can examine its world.

2001-09-05  Gary Thomas  <gthomas@redhat.com>

        * src/stand_alone/eth_drv.c (eth_drv_init): Don't initialize
        structures if ESA is zero.  This is used by low level drivers
        to indicate that a device is present, but can't currently be
        used.  The eCos driver handles this case as well.

2001-08-31  Hugo Tyson  <hmt@redhat.com>
2001-08-31  Andrew Lunn <Andrew.Lunn@ascom.ch>

        * src/net/eth_drv.c (eth_drv_tx_done): Guard against a NULL key
        return - which can be caused by race conditions in the driver,
        this is the neatest fixup.  It's good defensive programming
        anyway and ASCOM's tests indicate a benefit for CASE 106059.

2001-08-22  Gary Thomas  <gthomas@redhat.com>

        * src/stand_alone/eth_drv.c: 
        printf() is no longer a part of RedBoot.  Thus all programs
        must use diag_printf() and related functions instead.

        * cdl/eth_drivers.cdl: Only enable warning/debug modes if RedBoot
        is present as the debug environment (since there are implicit
        dependencies on RedBoot functions).

2001-08-20  Jonathan Larmour  <jlarmour@redhat.com>

        * src/net/eth_drv.c (eth_drv_send): Move endif location to fix build
        error.

2001-08-17  Jonathan Larmour  <jlarmour@redhat.com>

        * cdl/eth_drivers.cdl (CYGSEM_IO_ETH_DRIVERS_DEBUG): Now booldata.
        * src/stand_along/eth_drv.c (eth_drv_tx_done): Use different
        value of CYGSEM_IO_ETH_DRIVERS_DEBUG for verbosity.

2001-08-14  Gary Thomas  <gthomas@redhat.com>

        * src/stand_alone/eth_drv.c (eth_drv_write): 
        (eth_drv_tx_done): 
        (eth_drv_read): Better handling of stacking (layering) of drivers.
        RedBoot (stand alone code) is designed to call into the eCos 
        stack and these changes make sure that this is done properly
        nested/stacked.  These changes also affect the behaviour positively
        for CR 902745-CR.

        * src/net/eth_drv.c (eth_drv_send): Add locking of driver while
        actual hardware routines are involved.  Since the same driver
        can be shared by both eCos and RedBoot, it is imperative that
        additional locking (in the form of locking the scheduler) be
        employed during this window to make sure that the hardware is
        handled in complete, consistent steps.  This helps with known
        bug CR 902745-CR.

2001-08-09  Hugo Tyson  <hmt@redhat.com>

        * src/net/eth_drv.c (eth_drv_recv): Add a pair of
        CYGARC_HAL_SAVE_GP()/CYGARC_HAL_RESTORE_GP() on entry and exit;
        this function is intercalled between RedBoot and the application.
        A minor re-org at the ending to accommodate these macros' nesting.
        (eth_drv_tx_done): CYGARC_HAL_SAVE_GP()/CYGARC_HAL_RESTORE_GP().

        * src/stand_alone/eth_drv.c (eth_drv_tx_done): Add a pair of
        CYGARC_HAL_SAVE_GP()/CYGARC_HAL_RESTORE_GP() on entry and exit;
        this function is intercalled between RedBoot and the application.
        Also make printing message about "tx_done for other key" also
        conditional on net_debug variable - it's commonplace.
        (eth_drv_recv): CYGARC_HAL_SAVE_GP()/CYGARC_HAL_RESTORE_GP().
        (eth_drv_copy_recv): CYGARC_HAL_SAVE_GP()/CYGARC_HAL_RESTORE_GP().

2001-07-03  Gary Thomas  <gthomas@redhat.com>

        * src/net/eth_drv.c (eth_drv_recv): Better cleanup when running
        out of mbufs - could have lost mbufs before.

2001-06-21  David Woodhouse <dwmw2@redhat.com>

        * src/stand_alone/eth_drv.c: Timeout when waiting for Ethernet
        driver to finish sending packet.
        * src/stand_alone/eth_drv.c: Don't delay if it's ready immediately.

2001-06-11  Gary Thomas  <gthomas@redhat.com>

        * cdl/eth_drivers.cdl: Make debug default for RedBoot.

2001-05-22  Jonathan Larmour  <jlarmour@redhat.com>

        * cdl/eth_drivers.cdl: New option: CYGSEM_IO_ETH_DRIVERS_PASS_PACKETS
        which replaces the static define in...
        * src/stand_alone_eth_drv.c: Rename ETH_DRV_PASS_PACKETS to
        new CDL option above.
        Also, ensure references to start_console/end_console are conditional
        on CYGSEM_IO_ETH_DRIVERS_DEBUG.

2001-05-22  Hugo Tyson  <hmt@redhat.com>
2001-05-22  Sanjay Bisen <Sanjay.Bisen@ascom.ch>

        * src/net/eth_drv.c (eth_drv_recv): Patch from Sanjay at Ascom; it
        leaked one mbuf if you run out of clusters.  Fix is simply to
        free m in addition to top.

        * src/net/eth_drv.c (eth_drv_run_deliveries): Fixed a warning with
        an int cast in HAL_CTRLC_CHECK().

2001-03-21  Gary Thomas  <gthomas@redhat.com>

        * cdl/eth_drivers.cdl: Fewer buffers needed in stand-alone mode.

2001-03-12  Hugo Tyson  <hmt@redhat.com>

        * cdl/eth_drivers.cdl: Permit defines for
        CYGPKG_IO_ETH_DRIVERS_STAND_ALONE and CYGPKG_IO_ETH_DRIVERS_NET.
        The generic i82559 driver needs to know, unfortunately; it calls
        its own DSR directly to unblock after a lost interrupt.  And you
        mustn't call the DSR under RedBoot == ....STAND_ALONE.

2001-01-15  Jesper Skov  <jskov@redhat.com>

        * src/net/eth_drv.c (eth_drv_init): Do not use enaddr if NULL.

2001-01-07  Gary Thomas  <gthomas@redhat.com>

        * cdl/eth_drivers.cdl: Add interface 'CYGPKG_NET_DRIVER_FRAMEWORK'
        to describe interdependencies between network stack and driver
        framework packages.

2001-01-04  Gary Thomas  <gthomas@redhat.com>

        * src/net/eth_drv.c (eth_drv_tx_done): Update count of Tx packets.

2000-12-11  Gary Thomas  <gthomas@redhat.com>

        * src/net/eth_drv.c (eth_drv_run_deliveries): Support ^C when
        using network based debug channel.

2000-12-02  Gary Thomas  <gthomas@redhat.com>

        * src/stand_alone/eth_drv.c (eth_drv_write): Debug: dump packet
        before calling hardware routine for improved usability.

2000-10-30  Gary Thomas  <gthomas@redhat.com>

        * include/eth_drv.h: Fix compile error in stand-alone mode.

2000-10-17  Hugo Tyson  <hmt@redhat.com>
2000-10-10  Andrew Lunn <Andrew.Lunn@ascom.ch>
        * cdl/eth_drivers.cdl: Add configury to disable the warnings about
        out of mbufs for receives.

        * src/net/eth_drv.c: The changes required for the above.

2000-09-28  Hugo Tyson  <hmt@redhat.com>

        * src/net/eth_drv.c (eth_drv_run_deliveries): Remove race
        condition; a chance to deliver could be delayed until "next time"
        if the DSR snuck in just right.

2000-09-14  Hugo Tyson  <hmt@redhat.com>

        * cdl/eth_drivers.cdl: Add configury to control new features.  All
        is controlled globally by CYGPKG_IO_ETH_DRIVERS_SIMULATED_FAILURES
        which is by default off, natch.

        * src/net/eth_drv.c (simulate_fail): Implement simulated failures
        in ethernet packet delivery - independent tx and rx dropping and
        rx packet corruption.  Also a "line break" drop-all feature.

2000-09-13  Gary Thomas  <gthomas@redhat.com>

        * src/stand_alone/eth_drv.c: Take out noisy dump when out of buffers.

2000-09-11  Hugo Tyson  <hmt@cygnus.co.uk>

        * src/stand_alone/eth_drv.c (eth_drv_write): If we timeout waiting
        for the write to complete, do reset the vectors to point to the
        application, rather just a bald "return".

2000-09-08  Hugo Tyson  <hmt@cygnus.co.uk>

        * include/netdev.h (NETDEVTAB_ENTRY): Work around feature of new
        version of CYG_HAL_TABLE_ENTRY() whereby no spaces are allowed.

2000-09-07  Jonathan Larmour  <jlarmour@redhat.com>

        * include/netdev.h (cyg_netdevtab_entry_t): Correct syntax for
        CYG_HAL_TABLE_TYPE

2000-09-04  Jonathan Larmour  <jlarmour@redhat.com>

        * include/netdev.h (cyg_netdevtab_entry_t): Apply CYG_HAL_TABLE_TYPE

2000-09-01  Hugo Tyson  <hmt@cygnus.co.uk>

        * src/stand_alone/eth_drv.c (eth_drv_dsr): New function, never
        called but maybe referenced in stand_alone context, which lets
        redboot work in the new world.

2000-09-01  Hugo Tyson  <hmt@cygnus.co.uk>

        * OVERVIEW: This is part of the change to the network stack to
        greatly reduce latencies both of (other) DSRs and of thread
        scheduling.  All the work that the network stack *and* individual
        ether drivers used to do in DSRs (including alarm callbacks and
        data copies to/from the device memory) is moved into a "fast
        network thread" instead.  It calls a device's "deliver" function
        to do the work that was previously in the DSR.  This is a separate
        thread so that it can be set higher priority than application
        threads in order to minimize packet loss (depending on the
        driver), if required (the application threads presumed to be
        higher priority in turn than the network thread).  A crucial
        consequence of this is that we are no longer locking against DSRs,
        so a plain mutex can be used rather than the global scheduler
        lock, thus simplifying all the splfoo/splx() style functions.

        These changes WILL BREAK individual device drivers until they are
        updated AND the standalone logical ether driver in this component,
        until it is updated also.

        * include/eth_drv.h (ETH_DRV_SC): Add "deliver" entry to struct
        eth_hwr_funs interface record; declare available DSR and flag for
        "needs delivery" in SC status field.

        * src/net/eth_drv.c (eth_drv_run_deliveries): New function,
        performs callbacks to deliver funcs for all devs that want it.
        (eth_drv_dsr): New function, sets flag in sc and calls up to net
        stack to schedule the fast network thread.
        (eth_drv_send): No need to lock scheduler here.

2000-08-29  Gary Thomas  <gthomas@redhat.com>

        * src/stand_alone/eth_drv.c: Use null buffer, (char *)0,
        instead of wasting memory - low level drivers must be designed
        to handle this case.

2000-08-28  Gary Thomas  <gthomas@redhat.com>

        * src/stand_alone/eth_drv.c: Use new configuration parameters.

        * cdl/eth_drivers.cdl: Add new configury to control number of
        internal buffers used by this layer.  Also exposed some of the
        debug flags here.

2000-08-25  Hugo Tyson  <hmt@cygnus.co.uk>

        * include/eth_drv_stats.h (ether_drv_stats): A little further
        diddling; have a bool to say whether the dot3 info is filled in.

2000-08-24  Hugo Tyson  <hmt@cygnus.co.uk>

        * src/net/eth_drv.c (eth_drv_ioctl): Implement ioctl() calls.
        sockio.h numbers SIOCGIFSTATS and SIOCGIFSTATSUD map to
        ETH_DRV_GET_IF_STATS and ETH_DRV_GET_IF_STATS_UD respectively.

        * include/eth_drv.h (ETH_DRV_GET_IF_STATS_UD): Add new device
        interface ioctl() numbers, to get the struct below filled in.
        Also pull in the definition include file (below).

        * include/eth_drv_stats.h (ether_drv_stats): New file: Define
        common structure for ether devices to return stats info to higher
        up, via an ioctl() call.  SNMP uses this.

2000-08-23  Gary Thomas  <gthomas@redhat.com>

        * src/stand_alone/eth_drv.c: 
        * include/eth_drv.h: Low level drivers now need to export a 
        function which returns the interrupt vector used by that interface.
        This allows outside code to determine this in a portable fashion.

2000-08-16  Gary Thomas  <gthomas@redhat.com>

        * src/stand_alone/eth_drv.c: 
        * include/eth_drv.h: Clean up warnings (better protyping).

        * src/stand_alone/eth_drv.c (eth_drv_write): Abandon sending
        packet if device goes not ready for a long time (in some cases,
        this is the only indication that the link is down).

2000-08-07  Gary Thomas  <gthomas@redhat.com>

        * src/net/eth_drv.c (eth_drv_recv): Add safety in case this gets
        called [from stand-alone code] while interface is not up.
        
        * src/stand_alone/eth_drv.c: 
        * include/eth_drv.h: Rework to more fully support mixed stand-alone
        and system (eCos) stacks.

2000-08-03  Gary Thomas  <gthomas@redhat.com>

        * cdl/eth_drivers.cdl: Reparent within I/O, not NET.  This allows
        for stand-alone use as well as support for other stack implementations.

2000-07-28  Hugo Tyson  <hmt@cygnus.co.uk>

        * src/eth_drv.c (eth_drv_recv): Assert that the length we're asked
        to deal with is at least an ether header, and also be defensive in
        any case; discard small packets.  [CASE 104206]

2000-07-26  Gary Thomas  <gthomas@redhat.com>

        * src/eth_drv.c: 
        * include/eth_drv.h: Change interfaces used by hardware layer to
        be "soft" (pointers to functions).  This will allow those drivers
        to be shared by applications and the ROM/debug environment.

2000-07-15  Gary Thomas  <gthomas@redhat.com>

        * include/eth_drv.h: Add [initial] extensions to let this
        layer work either in an eCos environment or stand-alone.

2000-07-11  Gary Thomas  <gthomas@redhat.com>

        * include/eth_drv.h: Add minimal PCMCIA support.

        * src/eth_drv.c (eth_drv_netdev): New function - used to find the
        ethernet device info for PCMCIA devices.

2000-06-23  Hugo Tyson  <hmt@cygnus.co.uk>

        * src/eth_drv.c (eth_drv_send): Do not consume an SG entry for
        zero length data; tolerate overflow of the SG.  Before this, pings
        of 6000 bytes crashed the system!

        You can now set net_debug to 2 to get quieter output; 1 gives the
        whole packet dump as before.

        * include/eth_drv.h (MAX_ETH_DRV_SG): Make this 16 so that an MTU
        made of all mbufs will not overflow.

2000-03-28  Gary Thomas  <gthomas@redhat.com>

        * src/eth_drv.c (eth_drv_recv): Tolerate running out of MBUFs
        instead of "panic"ing.

2000-03-08  Gary Thomas  <gthomas@redhat.com>

        * src/eth_drv.c: Add some function [block] comments.
        (eth_drv_send): Use eCos scheduler lock instead of interrupt lock.

2000-03-08  Hugo Tyson  <hmt@cygnus.co.uk>

        * doc/driver_doc: Add some clarification about what's called when,
        proofreading results, shorter lines so I can print it nicely.

2000-03-06  Gary Thomas  <gthomas@redhat.com>

        * src/eth_drv.c: 
        * include/eth_drv.h: 
        * doc/driver_doc: Remove generic "priv"ate references.

2000-02-29  Gary Thomas  <gthomas@cygnus.co.uk>

        * src/eth_drv.c: 
        * include/eth_drv.h: New expanded API for hardware drivers.

2000-02-18  Gary Thomas  <gthomas@cygnus.co.uk>

        * src/eth_drv.c (eth_drv_send): Disable interrupts while initiating
        the buffer send - avoid a possible race.

2000-02-08  John Dallaway  <jld@cygnus.co.uk>

        * cdl/eth_drivers.cdl:
        Reparent under CYGPKG_NET and tidy display strings.
