[PATCH] virtio: Work around frames incorrectly marked as gso
From: Anton Ivanov <anton.ivanov at cambridgegreys.com>
Some of the frames marked as GSO which arrive at
virtio_net_hdr_from_skb() have no GSO_TYPE, no
fragments (data_len = 0) and length significantly shorter
than the MTU (752 in my experiments).
This is observed on raw sockets reading off vEth interfaces
in all 4.x and 5.x kernels I tested.
These frames are reported as invalid while they are in fact
gso-less frames.
This patch marks the v...

[PATCH v2 net 0/2] drivers/net,ipv6: Fix IPv6 fragment ID selection for virtio
The virtio net protocol supports UFO but does not provide for passing a
fragment ID for fragmentation of IPv6 packets. We used to generate a
fragment ID wherever such a packet was fragmented, but currently we
always use ID=0!
