As far as I can see this means a bridge interface no longer works when
set to dhcp on boot, as the above assumes devd will start dhclient.
Firstly it does not generate link-state events which I patched for
(same as the recent tap(4) change) but the bridge also doesn't support
the SIOCGIFMEDIA ioctl to match "ethernet" in the 2nd part of the
rule.

notify 0 {
        match "system"          "IFNET";
        match "type"            "LINK_UP";
        media-type              "ethernet";
        action "/etc/rc.d/dhclient quietstart $subsystem";
};

What is the best way to fix this?
