Description Octav Chipara 2010-11-10 01:17:06 UTC

I've been using ath5k in adhoc mode. I'm transmitting a lot of UDP (ping) packets. After a while I'm getting the following error:

ath5k phy1: no further txbuf available, dropping packet 

This is quite repeatable. I have tried to update to the latest version of the driver. Here is the mod info:

Any help figuring this out would be great!

Leaking txbuf in IBSS mode?  Can you recreate this at all in managed mode?

Closed due to lack of response...
