		May be we have to add a brief description for Rx/Tx
diagrams.

		I still wonder what you meant. I guess you want there is
only one
		generator for jam, preamble, and pad. Is it right ?

		Ehm... we plan flow control will recognize pause frame from
Rx, and then

information for Tx

		Thanks for your advices.
