It is not only checksumming, but also TSO. TSO, like checksumming,
is a feature where the chip must parse the packet to figure out where
to do it's work. In fact, TSO is a prime suspect for VLAN problems
as the card must duplicate the VLAN headers properly as it chops
up the TSO frame into MSS sized pieces.
