Description

After upgrading from 5.4 -> 5.4.1 an ifconfig directive long used in /etc/rc.conf no longer works.

ifconfig_xxx="DHCP"
ifconfig_xxx_alias0="link 00.11.22.33.44.55"

The alias link directive allows easily changing network cards on local machines which receive DHCP addresses based on mac address, without requiring changes to dhcpd.conf on router. However, after upgrading to 5.4.1 the directive no longer changes the mac address, causing machines to receive a different IP address from the router than what is expected by NSD and other machines on network.

Correction: ifconfig_xxx_alias0="link 00:11:22:33:44:55"

Should be obvious, just clarifying...

Thanks for the bug report.

I made a change to the alias config code recently that changed the behavior a bit. Aliases should be additional IPv4/IPv6 addresses for an interface, i.e.,

ifconfig_<ifname>_aliasX="inet ..." 
    ipv6_ifconfig_<ifname>_aliasX="inet6 ..."

Since you want to change the MAC address, please try:

ifconfig_<ifname>="link 00:11:22:33:44:55 DHCP"

I believe this will work for you.

Indeed it did work, and it's one less line in rc.conf, which is always good. Thanks for the prompt reply.
