From: Ron Mercer <ron.mercer@...gic.com>
To: netdev@...r.kernel.org
Cc: ron.mercer@...gic.com
Subject: [PATCH 4/7] qla3xxx: bugfix: Jumbo frame handling.
Fixed rx checksum bits. Turn on TCP processing for rx checksum.
Fixed max frame length register write. It wasn't getting set
in multi-port system. Set rx buffer queue length properly
for jumbo frames.
