Message-ID: <1442499839-22762-3-git-send-email-Yuval.Mintz@qlogic.com>
Date: Thu, 17 Sep 2015 17:23:51 +0300
From: Yuval Mintz <Yuval.Mintz@...gic.com>

Subject: [RFC v2 net-next 02/10] qed: Add basic L2 interface
From: Manish Chopra <Manish.Chopra@...gic.com>
This patch adds a public API for a network driver to work on top of QED.
The interface itself is very minimal - it's mostly infrastructure, as the
only content it has after this patch is a query for HW-based information
required for the creation of a network interface [I.e., no actual
protocol-specific configurations are supported].
