I have machine which have span port from physical switch for VMs.

Interface config:
auto eth3
allow-hotplug eth3
iface eth3 inet manual
        up /sbin/ifconfig $IFACE up
        downp /sbin/ifconfig $IFACE down

        post-up ethtool -K eth4 sg off
        post-up ethtool -K eth4 tso off
        post-up ethtool -K eth4 gso off
        post-up ethtool -K eth4 gro off
        post-up ethtool -K eth4 lro off
        post-up ethtool -K eth4 tco off

auto vmbrspan
iface vmbrspan inet manual
        bridge_ports eth3
        bridge_stp off
        bridge_fd 0
        post-up /usr/sbin/brctl setageing $IFACE 0

It worked in proxmox 2.3.x, but after upgrade to 3.0-23 i can't see span
traffic from inside VMs.
I can see mirrored data on host node, both on eth3 and on vmbrspan, but
not on tapXXXiY interface.
Any ideas?
