From 5d7c64a70fa15aef903469b05ca664f7cd17d769 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Tue, 27 Jun 2017 00:50:22 -0700 Subject: [PATCH] nfp: move representors' struct net_device_ops to shared code Apps shouldn't declare their own struct net_device_ops for representors, this makes sharing code harder. Add necessary nfp_app callbacks and move the definition of representors' struct net_device_ops to common code. Signed-off-by: Jakub Kicinski Reviewed-by: Simon Horman Signed-off-by: David S.
