Subject: [PATCH v2 3/8] qed: Send BW update notifications to the protocol drivers.

From: Sudarsana Reddy Kalluru <skalluru@...vell.com>

Management firmware (MFW) send a notification whenever there is a change in
the bandwidth values. The patch adds driver support to send this info to
the upper layer drivers (e.g., qedf).
