bge drivers does not work for 3COM 3C996-SX / 3C996B-T

[Hideki Yamamoto]

Hi, 

I tried today's 4.9-stable on a FreeBSD box with two 3COM 3C996-SXs and
two onboard BMC5703 chips.  3COM 3C996-SX boards are linkup, but the
other side, an SX I/F on SUN F280 is not linkup. 
When doing ping command to SUN, LED on 3C996 are brinking but 
nothing happens to SUN board.
I changed bge0 to bge2, but the situation is the same.
Hardware diagram is as follows.  bge0 can connect to the router or
another PC with intel SX board. 
Is this related to AUTO negotiation?  I cannot find any parameters
about AUTO negotiation in 'bge' driver source.

Any help would be greatly appreciated.
