Subject: net,via-rhine: Fix tx_timeout handling
From: Richard Weinberger <richard@xxxxxx>
[ 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:
