This patch introduce new TX offload flags for device that supports IP or UDP tunneled packet L3/L4 checksum and TSO offload. It will be used for non-standard tunnels. The support from the device is for inner and outer checksums on IPV4/TCP/UDP and TSO for *any packet with the following format*: <some headers> / [optional IPv4/IPv6] / [optional TCP/UDP] / <some headers> / [optional inner IPv4/IPv6] / [optional TCP/UDP] For example the following packets can use this feature: 1. eth / ipv4 / udp / VXLAN / ip / tcp 2. eth / ipv4 / GRE / MPLS / ipv4 / udp Please note that specific tunnel headers that contain payload length, sequence id or checksum will not be updated.
