Hello again !
Using socket qemu was a bit tricky, trying to get to <socketed>
interface leads to machine hang when doing ifconfig up on the second
interface (probably the addr argument is wrong).
Anyhow , trunk should work on one interface and it does but once again
only with roundrobin, NO LACP :(
the qemus is now using :
-net nic,model=virtio,macaddr=52:54:00:12:01:01,addr=0x12 -net
socket,mcast=230.0.0.1:42421
and
-net nic,model=virtio,macaddr=52:54:00:12:01:02,addr=0x12 -net
socket,mcast=230.0.0.1:42421
