From: Richard Weinberger <rich...@nod.at>
[ Upstream commit a926592f5e4e900f3fa903298c4619a131e60963 ]
rhine_reset_task() misses to disable the tx scheduler upon reset,
this can lead to a crash if work is still scheduled while we're resetting
the tx queue.
Fixes:
[ 93.591707] BUG: unable to handle kernel NULL pointer dereference at 0000004c
[ 93.595514] IP: [<c119d10d>] rhine_napipoll+0x491/0x6
