Subject: veth: set peer GSO values

From: Stephen Hemminger <stephen@networkplumber.org>


[ Upstream commit 72d24955b44a4039db54a1c252b5031969eeaac3 ]

When new veth is created, and GSO values have been configured
on one device, clone those values to the peer.

For example:
   # ip link add dev vm1 gso_max_size 65530 type veth peer name vm2

This should create vm1 <--> vm2 with both having GSO maximum
size set to 65530.
