	I tested following environments:

	AX88178(GbE), AX88172(100), AX88772(100), bge(GbE), re(GbE), rl(100)

		patched:	AX88178, AX88172, AX88772 <-> bge
		old:		AX88178, AX88172, AX88772 <-> bge
		patched:	AX88178, AX88172, AX88772 <-> rl
		old:		AX88178, AX88172, AX88772 <-> re

	My environment, there are 3 machines:
	+--+----+-------------+----+ (All port GbE L2SW)
	   |    |             |
	 bge  re          rl
	     (patched)   (old)

	 bge: FreeBSD 7.2-stable
	  re: FreeBSD 9-current
	  rl: FreeBSD 8.0-beta4


	For test environments:
	+--+----+---+---+---+     +--+-----+--+------+---+
	   |    |       |            |        |      |
	 bge  re  rl-axe        bge  re-axe    rl
	           (old)            (patched)


	According to netperf,

	patched:	AX88178, AX88172, AX88772 <-> bge
			 60Mbps,  60Mbps,  25Mbps
	patched:	AX88178, AX88172, AX88772 <-> rl
			 90Mbps,  60Mbps,  40Mbps

	old:		AX88178, AX88172, AX88772 <-> bge
			180Mbps,  90Mbps,  95Mbps
	old:		AX88178, AX88172, AX88772 <-> re
			180Mbps,  90Mbps,  95Mbps

	Ummmm, I'll try to update old(rl) machine to pached, and re-test.

	Thank you.
