SubjectRe: [Ilw] Re: 3.4-rc2, ilwagn still most of the time completely unusable
Hi Johannes,

Sorry for the late reply, I was travelling around the world ...
I have now tested the =2 and =4 settings at home, with the following
outcome:

11n_disabled=2:
lots of messages
Open BA session requested for 00:0a:79:eb:56:10 tid 0
BA request denied - HW unavailable for tid 0
and
Rx BA session stop requested for 00:0a:79:eb:56:10 tid 0 inititator reason: 0
Rx A-MPDU request on tid 0 result 0

Connection is stable for quite some time, but after 1-2 hours I got
a bad hang, grinding to a halt. pings to kernel.org gives 26%
packet loss, but the rest of the packets are fast 130ms

(Isn't that a strange thing - 25+% packet loss and all others are fast?)
I assume the packaet loss is related to the above messages.


11n_disabled=4:

lots of messages
Rx A-MPDU request on tid 0 result -22
and at some point ping timeouts of 80+ secs (!) and then total hang
(as far as I remember)

Best wishes

Norbert
