There's some documentation of the issues in the man page for utilities/ovs-vlan-test. The problem is actually more complex than I think you realize and the specific issue that you are running into (resulting from trunking vlans to VMs) I believe is actually not that common. If you have suggestions for improving the documentation, patches are welcome but I don't think blanket advice to disable offloading is actually correct for the majority of people. _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss
