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.
