Merge branch 'virtio_net-infinite-loop'
Balazs Nemeth says:
====================
net: prevent infinite loop caused by incorrect proto from virtio_net_hdr_set_proto
These patches prevent an infinite loop for gso packets with a protocol
from virtio net hdr that doesn't match the protocol in the packet.
Note that packets coming from a device without
header_ops->parse_protocol being implemented will not be caught by
the check in virtio_net_hdr_to_skb, but the infinite loop will still
be prevented by the check in the gso layer.
Changes from v2 to v3:
- Remove unused *eth.
- Use MPLS_HLEN to also check if the MPLS header length is a multiple
of four.
