Subject: [PATCH] e1000: resolve tx multiqueue bug
Date: Fri, 18 Jul 2008 18:05:30 +0100	[thread overview]
Message-ID: <20080718170529.GD10471@solarflare.com> (raw)
In-Reply-To: <20080718165128.GC10471@solarflare.com>

With the recent changes to tx mutiqueue, e1000 was not calling
netif_start_queue() before calling netif_wake_queue().
This causes an oops during loading of the driver.

(Based on commit d55b53fff0c2ddb639dca04c3f5a0854f292d982.)
