From: Jacob Keller Date: Fri, 16 Oct 2015 17:56:56 +0000 (-0700) Subject: fm10k: set netdev features in one location X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e0244903d4a6a27f9f1e8b46b89afa4130aa9164;p=linux-beck.git fm10k: set netdev features in one location 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.
