From 19252ecb672d3f35959c576d1d26b9aca350f5bf Mon Sep 17 00:00:00 2001 From: Nick Kossifidis Date: Fri, 3 Dec 2010 06:05:19 +0200 Subject: [PATCH] ath5k: Always free tx buffers before reset * Always free tx buffers before reset, since we also empty hw queues. If we don't and a queue gets stuck, we'll never decrease txq_len and sw will keep thinking the queue is still stuck even after reset.
