From 7344bea1401627cd1b02d19252baa1c40c0fb5e9 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Fri, 18 Aug 2017 15:48:17 -0700 Subject: [PATCH] nfp: store pointer to MAC statistics in nfp_port Store pointer to device memory containing MAC statistics in nfp_port. This simplifies representor code and will be used to dump those statistics in ethtool as well. Signed-off-by: Jakub Kicinski Reviewed-by: Simon Horman Signed-off-by: David S.
