If you think that this a problem with the igb driver then the Intel driver mailing lists or netdev might be more likely to give you a useful response. It could also be related to vlan tags - those have had problems in the past but shouldn't be an issue at this point. _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss
