ip: add support for buffer offload metadata in ip midchain
The offload should be handled by gso node or by the NIC
if the latter has the relevant capabilities. But ip midchain
is missing the support for buffer offload metadata in case
of GSO packet.
This patch adds the relevant support to add the buffer metadata
if the packet is GSO/IPIP to be handled accordingly.
Type: improvement
