[ofa-general] What is the size of async event queue ?

[Tang, Changqing]

Or:
	I think I find the SPEC part talking about zero-length message.
I just search zero-length.
	For rdma write, the receiver side does not need to do anything,
for send, a receive
WR is need in receiver side. And that makes sense.
