There are many offload capabilities defined that are not well thought 
out.  In particular we do not distinguish between ipv4 and ipv6 for 
things like cksum and tso so there's no way to disable individual 
features.  The ability to tweak LRO is clearly needed and clearly belong 
as an ifnet capability but unilateraly deciding this is the wrong approach.
