I had a wild guess and plug'ed in the RJ-45 into the server's 2nd port, modified
/etc/rc.conf, booted and all was fine:
$ ssh 192.168.178.5
$ uname -a

If I compare the ifconfig-values of the not working bce0 (see below) and now
bce1,
there is no difference.
It is somewhat magic, that bce0 stopped working after the first boot of
the new kernel.
