I have split the patch into a set: cleanups, new infrastructure, and
actual allocation change in add buffers: add_recvbuf_big,
add_recvbuf_small, add_recvbuf_mergeage per your suggestion, and also in
recv buffers: recv_big, recv_small, recv_mergeable.

I hope you will agree with it. I am testing the patch-set now, will
submit it soon after finishing all test cases.

Thanks
Shirley
