brcmsmac TCP problems and txop exceeded

Hi, this thread should be a continuation of one I started about a month ago and
can be found here:

http://comments.gmane.org/gmane.linux.kernel.wireless.general/86324

(I lost the header to it and inadvertantly cross posted into another thread, my
apologies for that)



So here goes:

I have the BCM4313 [14e4:4727] (rev 01)

When using wireshark, I see that I am getting many {TCP Retransmission,TCP Dup
ACK,TCP RST} with {TCP, HTTP, SSH} when using brcmsmac driver in the 3.2.1
kernel.  I've tried 3.3-rc5 kernel with similar results.

I notice a lot of these popping up in /var/log/messages as well:

ieee80211 phy0: wl0: brcms_c_d11hdrs_mac80211:  txop exceeded phylen 155/256 dur
1746/1504
ieee80211 phy0: wl0: brcms_c_d11hdrs_mac80211:  txop exceeded phylen 130/256 dur
1546/1504
ieee80211 phy0: wl0: brcms_c_d11hdrs_mac80211:  txop exceeded phylen 130/256 dur
1546/1504


any ideas how to solve this?


Regards,
