I was looking for this in the ah.h and the ah_desc.h files. Are they
someplace else, or maybe this is a system call? I can't find anything
about the retry limit (<-- CWmin = retry?) Thanks,
CWmin is a setting that controls the random delay before packets
are transmitted. Search for tqi_cwmin in the driver. The retry limit
says how many times the MAC should retry if it gets a collision
while trying to transmit - I think it is controled by the tqi_shretry
and tqi_lgretry values. In the driver in 6.X you can (in principle)
set these values at the time the transmit queues are configured.
You need to set cwmin on the tx q as David describes. Be sure to set
the parameters you set into the hardware; check the wme update code for
the correct logic. For the other thing just set the tx descriptor to do
1 try.
