From: Sridhar Samudrala <s...@us.ibm.com>
commit 8e1e8a4779cb23c1d9f51e9223795e07ec54d77a upstream.
Found this problem when testing IPv6 from a KVM guest to a remote
host via e1000e device on the host.
The following patch fixes the check for IPv6 GSO packet in Intel
ethernet drivers to use skb_is_gso_v6(). SKB_GSO_DODGY is also set
when packets are forwarded from a guest.
