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
