No luck, I'm afraid (as was expected).  No PHY can be found
on any of the addresses.  The PHY addresses 2 and 31 return
0x0000, all others return 0xffff.

While debugging and searching I found this message from
David Christensen:

It seems that the PHY on the 5709S is different from the
others and requires some non-trivial code to be written.  :-(
I posted a follow-up in the freebsd-net list and copied
David.  Maybe he has some news.

This whole issue is quite important.  IBM is phasing out
the previous blade generation (HS21), so all new blades
are HS22 which have the BCM5709S interfaces.  As it stands
now, FreeBSD cannot be used on IBM blades.

Best regards
