I think there's not much point to LRO except when not using connected
mode. Especially since checksum offload doesn't work for connected mode.
IIRC "the linux stack" does have integrated copy and checksum on
receive, at least in some cases. I suppose that if LRO would coalesce
several sub-MSS segments it might still provide value but I wasn't sure
if it would and if so how much that buys one. My IPoIB setup is getting
long-in-the-tooth and isn't even up at the moment :(
