Hi,
I was testing monitor mode with ath9k_htc and my laptop got slower. Then
I noticed this:
[ 9246.606150] ath: No free RX buffer
[ 9246.606156] ath: No free RX buffer
[ 9246.606582] ath: No free RX buffer
[ 9246.606590] ath: No free RX buffer
And I saw it quite a lot:
$ grep "ath: No free" /var/log/syslog | wc -l
870950

Thanks! I will run more tests with monitor mode next week and will let
you know if I see it again.

What compat-wireless version are you running? I use some ath9k_htc
devices at home and would be glad to help do some debugging.

Kalle thanks, now I could easily get this thing in monitor mode itself
in a busy channel (6, HT20).
will fix this soon.
issue can be found with latest compat-wireless/wireless-testing
