Subject: [PATCH 3/8] qed: Send BW update notifications to the protocol drivers.
Date: Thu, 26 Mar 2020 00:08:01 -0700 [thread overview]
Message-ID: <20200326070806.25493-4-skashyap@marvell.com> (raw)
In-Reply-To: <20200326070806.25493-1-skashyap@marvell.com>
From: Sudarsana Reddy Kalluru <skalluru@marvell.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).
