Aha. So I added bpf to my kernel config, recompiled and
installed everything again.

Yesterday this PC has been upgraded from 4.10 to most
recent 5.3. I have in /etc/rc.conf

    ifconfig_rl0="DHCP"

which worked jsut fine with 4.10, but seems to misserably
fail with 5.3.

Dhclient binds rl0 to 192.168.1.22 all the time, which
seems to be a kind of default for a failing dhclient.

Is something else, unusual, needed in 5.3, that is critical
to dhclient?

Rob.
