From 3607c44676583e80122c1fed23f34d003cdd6979 Mon Sep 17 00:00:00 2001 From: Ursula Braun Date: Mon, 8 Oct 2007 20:28:47 -0700 Subject: [8021Q]: transfer dev_id from real device A net_device struct provides field dev_id. It is used for unique ipv6 generation in case of shared network cards (as for the OSA network cards of IBM System z). If VLAN devices are built on top of such shared network cards, this dev_id information needs to be transferred to the VLAN device. Signed-off-by: Ursula Braun Signed-off-by: David S.
