link aggregation agr



I had link aggregation working between a NetBSD-current/i386 box and a
HP switch until last week. With 15 May 2008 source:

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.

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..

A trace of a boot is appended.

vr0: old pstate 2<TIMEOUT>
vr0: new pstate 3d<ACTIVITY,AGGREGATION,SYNC,COLLECTING,DISTRIBUTING>

yet
        agrport: vr0, flags=0x0

? The "new pstate" just doesn't seem to happen...

Thoughts?

Cheers,

Patrick
