Hi,
I use the 2.6.32 kernel on a Debian system. I use the module
mac80211 for my Wifi card. But in more and more numerous cases,
I cannot get an IP with dhclient. It fails. While it searches
for one, I get:
wl0: wlc_d11hdrs_mac80211: AC_BE txop exceeded phylen 366/186
Is it a bug in the module? I found some info but not about some
patch or fix. Is there a fix in the recent kernel? What release
should I use? If no patch, is there some workaround?
Thanks,
Sincerely,

The message itself means that according to the driver we get a transmit
packet that exceeds the WMM txop. This message itself does not prevent
the packet from being transmitted. I have not seen the message lately in
recent driver versions.
You can either try compat-wireless (see [1]), which should support
2.6.32. Or you can try the latest 3.3 kernel.
btw. 9 out of 10 times not getting an IP with dhclient means a problem
with security credentials/handshake/etc. So if the option above do not
solve your problems, we have to dive into that.
