This situation is different from your's Rao.

That proposal was to add indirect calls for things the TCP stack
internally can make internal state checks for.

Whereas this current patch discussed here is a driver offload hook,
which TCP cannot internally possibly know anything about.

I am fine with what Boris et al. are doing here.  It is a different
situation than your's.
