  Log:
  First step of TSO (TCP segmentation offload) support in our network stack.
  
   o add IFCAP_TSO[46] for drivers to announce this capability for IPv4 and IPv6
   o add CSUM_TSO flag to mbuf pkthdr csum_flags field
   o add tso_segsz field to mbuf pkthdr
   o enhance ip_output() packet length check to allow for large TSO packets
   o extend tcp_maxmtu[46]() with a flag pointer to pass interface capabilities
   o adjust all callers of tcp_maxmtu[46]() accordingly
