> Subject: [dpdk-dev] [PATCH v2 10/13] mbuf: generic support for TCP segmentation offload
> 
> Some of the NICs supported by DPDK have a possibility to accelerate TCP
> traffic by using segmentation offload. The application prepares a packet
> with valid TCP header with size up to 64K and deleguates the
> segmentation to the NIC.
> 
> Implement the generic part of TCP segmentation offload in rte_mbuf. It
> introduces 2 new fields in rte_mbuf: l4_len (length of L4 header in bytes)
> and tso_segsz (MSS of packets).
> 
> To delegate the TCP segmentation to the hardware, the user has to:
> 
> - set the PKT_TX_TCP_SEG flag in mbuf->ol_flags (this flag implies
>   PKT_TX_TCP_CKSUM)
> - set PKT_TX_IP_CKSUM if it's IPv4, and set the IP checksum to 0 in
>   the packet
> - fill the mbuf offload information: l2_len, l3_len, l4_len, tso_segsz
> - calculate the pseudo header checksum without taking ip_len in account,
>   and set it in the TCP header, for instance by using
>   rte_ipv4_phdr_cksum(ip_hdr, ol_flags)
> 
> The API is inspired from ixgbe hardware (the next commit adds the
> support for ixgbe), but it seems generic enough to be used for other
> hw/drivers in the future.
> 
> This commit also reworks the way l2_len and l3_len are used in igb
> and ixgbe drivers as the l2_l3_len is not available anymore in mbuf.
