Fri 17 Jan 2014 09:38:33 PM UTC, comment #1: I'm not sure this is the right approach. It might be for the VLAN ID, but the priority rather depends on the actual packet to be sent. I think adding this per pcb would be a better approach. This way, you could prevent adding a VLAN header to all packets, even if the VLAN ID and priority stay at 0. |
