Date: Wed, 22 Jan 2014 15:49:21 -0800 From: Sridhar Samudrala <sri@...ibm.com> To: "netdev@...r.kernel.org" <netdev@...r.kernel.org> Subject: VLAN ID 0 with priority tagging I am trying to send a packet with VLAN ID 0 and non-zero priority. The VLAN interfaces are created on 2 hosts using ip link add link eth1 eth1.0 type vlan id 0 egress-qos-map 0:2 When i try to send a packet using ping/arping, on the sender side tcpdump shows that the VLAN tag is added with ID 0 and priority 2. However, the receiver is receiving the packet with vlan tag stripped. I am seeing the same behavior with multiple NICs and also with a switch in between the 2 hosts or with the 2 hosts connected over loopback cable. It looks as if the driver on the send side is stripping the tag if vlan id is 0. Is this correct behavior or a bug? Any clues on how to get priority tagging to work with vlan id 0?
