My apologies. I had been using gmac all along but it appears to be an
intermittent problem. Sometimes the interface comes up in time for IP
autoconfig and sometimes not. I'll go have a look at the IP config code
to see if get it to wait a while for the interface to come up.

Here's a successful (garbled) log where the link came up just in time (i
can't capture the failed log as I don't have a serial port on my iMac).

eth0: PHY ID: 0x00406212

. OK
