From c70ce028e834f8e51306217dbdbd441d851c64d3 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Mon, 21 Mar 2016 09:55:10 -0700 Subject: net/rtnetlink: add IFLA_GSO_MAX_SEGS and IFLA_GSO_MAX_SIZE attributes It can be useful to report dev->gso_max_segs and dev->gso_max_size so that "ip -d link" can display them to help debugging. For the moment, these attributes are read-only. Signed-off-by: Eric Dumazet Cc: Petri Gynther Cc: Stephen Hemminger Signed-off-by: David S.
