Subject: [PATCH net-next 0/4] packet: tpacket gso and csum offload
From: Willem de Bruijn <willemb@...gle.com>
Extend PACKET_VNET_HDR socket option support to packet sockets with
memory mapped rings (PACKET_RX_RING, PACKET_TX_RING).
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.
Willem de Bruijn (4):
packet: move vnet_hdr code to helper functions
packet: vnet_hdr support for tpacket_rcv
packet: parse tpacket header before skb alloc
packet: tpacket_snd gso and checksum offload
