Hi, I've tested brcmsmac in 3.2 and 3.3, and it really is not stable enough to
use for me. I have the BCM4313 [14e4:4727] (rev 01)
One noticeable problem is trying to SSH is nearly impossible (including sftp and
sshfs mounting). Also web browsing slows to a crawl and eventually tanks.
I'd like to know how to debug this, and if there are any known issues.
TIA,
ng

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?
Thanks,
Naveen

Starting a new thread (I hope)
These messages are only indicating (possible) violation of the WMM txop
parameter. So what problem are you looking into here beside the issues
you observe in wireshark. I mean the problem that made you decide to run
wireshark.
