Message-ID: <20170424170049.16027-5-manish.chopra@cavium.com>
Date: Mon, 24 Apr 2017 10:00:47 -0700
From: Manish Chopra <manish.chopra@...ium.com>
To: <davem@...emloft.net>
CC: <netdev@...r.kernel.org>, <Yuval.Mintz@...ium.com>
Subject: [PATCH net-next 4/6] qede: Configure UDP ports in local context.
This patch configures UDP ports locally instead of
configuring them in deferred context which would be
helpful in synchronizing UDP ports configuration for VFs
which will be enabled in further patches.
