Subject: [PATCH V2 net-next 1/2] qed: Add support for hardware offloaded FCoE.
From: Arun Easi <arun.easi@...gic.com>
This adds the backbone required for the various HW initalizations
which are necessary for the FCoE driver (qedf) for QLogic FastLinQ
4xxxx line of adapters - FW notification, resource initializations, etc.
