Also please remember that most card have a maximum lifetime
for packet in the Tx queue. If I remember correctly, we mapped it
properly to the "retry" option of iwconfig/iwlist (i.e. iwconfig allow
you to both change the retry number and the retry lifetime).
Then, you also have the watchdog timer of the Linux networking
stack that will kick in at some point, so you need to take care of
And the reason why you don't want this number to go to high is
for latency, and because the transport will do it's own
retransmissions at some point.
