Well, what's rate=0 mean?

And 0x8000 is bit 11 set, which is HT40. I definitely don't have HT40 enabled.

0x8000 is bit 15 set, which means "antenna B", I think?

Duh, sorry. was tired. :(

But then I can't seem to figure out what rate=0 means either. Should be
an OFDM rate (bit 9 not set) but 0 isn't a valid OFDM rate value. Hmm.

That's why I'm confused too.

I'm seeing some odd behaviour here where sometimes the NIC behaves
fine, and sometimes it just gets long transmit failures on OFDM frames
but is fine with CCK frames. That's why I'm digging into this.

I also see the sensitivity tuning code lose the plot over time as OFDM
errors are returned by the receiver and it keeps trying to compensate
until it's maxed out the sensitivity tuning parameters. If I restart
the NIC, it all comes back to normal for a while.

Do any of these ring a bell?

Sorry, no.
