You could have two rings, one for Tx cmds another for non-tx cmds,
what I am trying to say is prefetching of a NOP does not cause any
harm, it wastes a few cpu cycles, I have logged the command
q length for my driver and found that a NOP would be executed after
33 Tx commands on the average under heavy load condition.

If I have free time I will definitely
do experiment with your driver and try to fix it as I have done to mine
for hp-ux.
My driver's design was exactly like yours but I had to change it.

BTW, how frequently do you send the multicast workaround for receiver lockup
bug? If the receiver is idle for two seconds and you have rx_bug set, right?
