The send_cmd function protected to attempt to call it if the Ethernet device was not
claimed before (previously it caused a problem with NULL pointer dereference
in the ioctl in kernel code).
Moved the Ethernet device name to a macro, so it is easier to modify it, when
someone tests in different machines (e.g. the 10Gb/s NIC for tests with
KC705 is p4p1, while 1Gb/s NIC for tests with Atlys is eth0) |

Changed handling of commands so, that all commands are now confirmed - even start and stop
(which previously were not confirmed - successful reception of start was confirmed
by sending of data packets (what if there was no data at the moment?), successful
reception of stop was confirmed by end of data stream).
Added also flushing of data stream after reception of stop command.
The receiver2t.c implements suggested method of communication with the FADE driver.
One thread is responsible for reception and processing of data, while another thread
is responsible for sending of control commands. |

The previous experimental implemenation for 10Gb/s links has been replaced with the
new, rewritten implementation, which uses sequential numbering of packets instaed
of "sets of packets". This allowed to simplify the driver, and improve its performance.
Additionally a possibility to send user defined commands to the FPGA was added. |

Added experimental version of my protocol, working with the 10Gb/s
link on the KC705 board.
The design has been initially tested, and is working, but it still
needs some improvments.
Please note, that this version uses the "jumbo" frames,
with 8192 bytes of user data in each packet (plus header).
Therefore it was necessary to make some changes in the kernel
driver. |

Corrected small bug in eth_sender8 (which in fact should only
generate a compiler warning, as the resulting bit vector
was anyway correctly truncated...) |

Updated test client program - receiver2.c
Added possibility to activate only selected slave in the command line.
Currently program services up to three slaves: 0, 1 and 2
To activate a slave, add its number as a program argument in the command line
(order doesn't matter). |

Added new version of the FPGA firmware, which does not rely on the Ethernet MAC core.
Now both versions are available.
The version with Ethernet MAC is in directory FPGA_with_MAC.
The version which handles directly Ethernet PHY is in directory FPGA_no_MAC |
