Re: Getting a 'no-ack' tx status?

[Ben Greear <greearb@candelatech.com>]

I think I managed to hack the CT firmware to return the
tx-completion status (OK, XRETRY, DROP) when it is returning the
tx-rate info, and patched the driver to pay attention to it...

A brief test showed some failed-retry counters reported by
the mac80211 stack, so that looks promising.

Will do some more testing when I get a chance.

Thanks,
Ben
