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.Sam
We do distinguish between TSO4 and TSO6, its just that all the pieces for 6 arent actually there yet, you are right about the cksum granularity, but I'm not convinced its needed. You might be right on the need to fine tune the functionality, but having a big ON/OFF doesnt seem a bad thing to me.
