This is amusing: now I have a connection, so now we have some console
output :-) (I must have rolled a 5 or 6)

agr0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500
        agrport: vr0, flags=0x0
        agrport: ex0, flags=0x3<COLLECTING,DISTRIBUTING>
        agrport: ex1, flags=0x0
        address: 00:0c:6e:03:86:01
        inet 192.168.200.21 netmask 0xfffff000 broadcast 192.168.207.255
        inet6 fe80::20c:6eff:fe03:8601%agr0 prefixlen 64 scopeid 0x6

I used to see <COLLECTING,DISTRIBUTING> for vr0 and ex1 too.

It seems that I have to be lucky and the dhcp request happens to go
through ex0.

tcpdump on vr0 and ex1 just shows me lacp traffic.
tcpdump on ex0 shows me "usual" traffic.

The mystery now is why those 2 interfaces don't start collecting and
distributing.. (The switch seems happy, it sees the cards' mac address
in the correct ports, which form part of the trunk.)
