Subject: [PATCH net-next 07/13] sfc: Correct comment about number of TX queues used on EF10

From: Shradha Shah <[email-masked]>
Date: Wed, 12 Feb 2014 18:59:19 +0000

From: Ben Hutchings <[email-masked]>

EF10 implements option descriptors to switch TX checksum offload
on and off between packets.  We could therefore use a single
hardware TX queue per kernel TX queue, although we don't yet.
