Motonori Shindo (CCed) reported to me recently that NetFlow does not
include VLAN headers in the byte counts that it exports. Taking a
look at the kernel datapath code, I see that ovs_flow_stats_update()
accounts raw skb->len to byte counters. I suspect that it should add
4 if a VLAN header was present but removed by VLAN acceleration.
Comments?
Thanks,
Ben.
