Link up problem between 1000base-SX(bge) and SUN

[Hideki Yamamoto]

Hello, 

I'm having a problem about link up between 1000base-SX(bge) and SUN.

I tried yesterday's 4.9-stable on a FreeBSD box with two 3COM
3C996-SXs and two onboard BMC5703 chips.  Two 3COM 3C996-SX board link
went up, but the other side, a 1000base-SX I/F on SUN F280 did not go
up.  When doing ping command to SUN from FreeBSD box, LED on 3C996
were brinking but nothing happened to SUN board.  I changed bge0 to
bge2, but the situation was the same.  Hardware diagram is as follows.
bge0 can send or receive packates 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.  I checked Linux 2.4.22 kernel source and have found the
several code about auto negotiation.  I wonder if a linux box works
well.  I do not need full support of auto negotiation, but sample code
that handles auto negotiation with Solaris machine.

Any help would be greatly appreciated.
