Hello John,

the goal would be to have a transmission as fast as possible while
ignoring, if a packet reached its destination or not. I'd like to test
wireless performance regarding transmission time in a dedicated
environment. As far as I can see, backoff might already push the
transmission times up quite a lot and if I'd even add the time of -
worst case - 10 retransmissions, the transmission time of one packet
will grow even more.

It would be second-rank, if the packet reaches its destination. Loss of
some packets is not a problem in my testbed.

So I'd like to disable usage of ACKs in order to be off with the only
problem - backoff. Disabling this would of course be nice, but I fear,
that's far more work that just disabling ACKs.

Dennis
