Merge branch 'tpacket-gso-csum-offload'
Willem de Bruijn says:
====================
packet: tpacket gso and csum offload
Extend PACKET_VNET_HDR socket option support to packet sockets with
memory mapped rings.
Patches 2 and 4 add support to tpacket_rcv and tpacket_snd.
Patch 1 prepares for this by moving the relevant virtio_net_hdr
logic out of packet_snd and packet_rcv into helper functions.
GSO transmission requires all headers in the skb linear section.
Patch 3 moves parsing of tx_ring slot headers before skb allocation
to enable allocation with sufficient linear size.
Changes
v1->v2:
- fix bounds checks:
- subtract sizeof(vnet_hdr) before comparing tp_len to size_max
- compare tp_len to size_max also with GSO, just do not truncate to MTU
