Subject: [PATCH] pch_gbe: Adding read memory barriers

Dear Linux Kernel Developers,

Please find attached, a patch to solve "Received CRC" errors reported by
the pch_gbe driver under heavy load. It occurred on an Intel ATOM E620T
while running a 300mbit/sec multicast network stream leading to a ~100%
cpu usage.

This patch got validated on the 3.2.16 kernel but also apply to the 3.x
family.

Getting it into stable would be perfect as it solves reliability issues.

Cheers,
Erwan Velu

First of all, for a patch which is not accepted yet you do not
CC: stable.

Second of all, do not put text in the main body of your email which is
unrelated to the patch and should not end up in the commit message.

Instead, post your patch to the appropriate primary mailing lists,
and if it's accepted it can then be submitted to -stable at some
later time.

Your patch posting email should be composed purely of the commit
log message in the message body, followed by the actual patch.

Otherwise the maintainer that applies your patch has to edit out
all of this other flowery text that is unrelated to the commit
and that makes more work for them.
