Message-ID: <1462799963-23547-10-git-send-email-Yuval.Mintz@qlogic.com>
Date: Mon, 9 May 2016 16:19:18 +0300
From: Yuval Mintz <Yuval.Mintz@...gic.com>
To: <davem@...emloft.net>, <netdev@...r.kernel.org>
CC: <Ariel.Elior@...gic.com>, Yuval Mintz <Yuval.Mintz@...gic.com>
Subject: [PATCH net-next 09/14] qed*: Support PVID configuration
This adds support for PF control over the VF vlan configuration.
I.e., `ip link ... vf <x> vlan <vid>' should now be supported.
1. <vid> != 0 => VF receives [unknowingly] only traffic tagged by
<vid> and tags all outgoing traffic sent by VF with <vid>.
2. <vid> == 0 ==> Remove the pvid configuration, reverting to previous.
Signed-off-by: Yuval Mintz <Yuval.Mintz@...gic.com>
