So, what should I enable? I guess there's a suspection of tx path
problem (since according to tcpdump, the other side sends packets
our way, but our side does not receive them), so -e brcmsmac_tx
shold be okay to enable (and should be easy to filter out if
needed, too, I guess). And using -e, now too, like this:
trace-cmd record -e brcmsmac -e brcmsmac_tx -e brcmsmac_msg -e mac80211 -e mac80211 -e cfg80211
http://www.corpit.ru/mjt/tmp/brcmsmac-4313-trace-201409232.dat.gz is
the result from the following:
modprobe brcmsmac (networkmanager is running)
trace-cmd as above &
wget http://ip-add-ress/random-file -O /dev/null
I waited for wget to stall (it d'loaded 240Kb) and hit
Ctrl+C.
The trace file isn't really that huge.
Thank you!
