veth: set peer GSO values
[ 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.
