This option sets the thread priority level used by the fast
network thread. The fast network thread runs often but briefly, to
service network device interrupts and network timeout events. This
thread should have higher priority than the background network
thread. It is reasonable to set this thread's priority higher than
application threads for best network throughput, or to set it lower
than application threads for best latency for those application
threads themselves, potentially at a cost to network throughput."

description "
If this is enabled, the fast network thread will tickle the
device(s) periodically, to unblock them when the hardware has
become wedged due to a lost interrupt or other hardware
race-condition type problem.
This is not necessary if a networked app is running which sends
packets itself often - or
uses TCP, or any similar protocol which exchanges keep-alive
packets periodically and often enough.
Trying to send a packet passes control into the driver; this is
sufficient to detect and unblock jammed hardware."
 
cdl_option CYGNUM_NET_FAST_THREAD_TICKLE_DEVS_DELAY {
display "Delay in kernel clocks of tickle loop"
flavor data
default_value 50
description "
The default is 50, which will usually mean a delay between
tests for 'stuck' devices of 500mS, that is half a second.
The overhead only applies if no network activity occurred,
so it may be acceptable to make this value very small,
where high CPU load does not matter during network idle
periods, or very large if your application tries often to
send packets itself."
