[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...

[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! v2: Add blank lines after declarations Ben.
