From: Dhananjay Phadke <dhananjay@...xen.com>
To: netdev@...r.kernel.org
Cc: davem@...emloft.net
Subject: [PATCH 05/13] netxen: download firmware from file
o optimize the onboard flash access routines by reducing udelays and
reordering some register writes.
o Add support to request firmware from filesystem, its validation
for compability. If firmware file is not found or validation fails,
fall back to firmware flashed on the card.
o Fail the pci probe if firmware init fails.
