Subject: [net-next 02/17] fm10k: set netdev features in one location
Date: Thu,  3 Dec 2015 16:29:39 -0800	[thread overview]
Message-ID: <1449188994-64940-3-git-send-email-jeffrey.t.kirsher@intel.com> (raw)
In-Reply-To: <1449188994-64940-1-git-send-email-jeffrey.t.kirsher@intel.com>

From: Jacob Keller <jacob.e.keller@intel.com>

Don't change netdev hw_features later in fm10k_probe, instead set all
values inside fm10k_alloc_netdev. To do so, we need to know the MAC type
(whether it is PF or VF) in order to determine what to do. This helps
ensure that all logic regarding features is co-located.
