looking for documentation on the 5704s, I notice that the 's' means: has no 'PHY' but a 'SERDES' physical layer. So the above diagnose does not apply, but the phenomena are still there: chip is detected, but no traffic What does a verbose bootup look like?

I added code to the bge(4) driver to set these registers during autoneg, and the link seems to be properly negotiated now, and traffic is exchanged correctly. A patch for this problem is available at http://www.freebsd.org/~wpaul/bge.diff. This patch has been supplied to the submitter and checked in to the FreeBSD-current sources. |
