linux-gen: pktio: update LSO capabilities
Increase max_segments capability to 64 segments. LSO implementation
does not have a limit, but is limited by number free packets
in the pool. Picked a large enough number that LSO capability
does not limit segmentation of a maximum size IP packet.
Increase max_payload_len capability to be closer to MTU. Subtract
min header size (only Ethernet header) from MTU, instead of the
maximum supported header size.
