New Revision: 207851
URL: http://svn.freebsd.org/changeset/base/207851
Log:
Implement TSO and TSO over VLAN. Increase number of allowed
fragmentation of mbuf chain to 32 from 16 because TSO can send 64KB
sized packet which in turn requires long list of mbuf chain. Due to
lack of documentation, I'm not sure whether driver have to pull up
ethernet/IP/TCP header with options to make controller work but
driver have to parse TCP header to update pseudo TCP checksum
anyway. The controller expects pseudo TCP checksum computed by
upper stack and the checksum should follow the MS NDIS
specification to make TSO work.

This brings in INET as a dependency for the driver and fails on my
nooptions INET
nooptions INET6
kernels (in_pseudo()).
