I was unable to get a coredump.  Entering 'panic' at the db> prompt
did not provide me with a core dump neither did 'call dodump'.
After syncing with today's HEAD I don't get the panic, though the
re(4) interface comes up I cannot pass data on the connection.

I have posted[1] the latest dmesg, pciconf, ifconfig and a tcpdump from
the laptop as it tries to ping my desktop using the re(4) interface.
The MAC addresses appear to be shifted the same as the first laptop as
I reported on IRC.

Yes, on dfly aue(4) operates at 10UTP on freebsd it operates at 100TX.
I can force the interface to 100baseTX full-duplex and it works but
slightly slower than 10UTP.

After syncing with HEAD the problem remains.
