I tried to use 802.1p priorities without setting up a VLAN ID. It seems to make it work, the only way is to create a VLAN interface
vconfig add eth0 0
Then I can send out packets onto eth0.0 with priorities. Here is the problem: when a DHCP request is sent out of
eth0.0, the switch sends back a DHCP offer packet without any VLAN header. Unfortunately, the packet is dispatched to eth0 interface instead of eth0.0. As the result, the DHCP client fails!
I had to work on a customized kernel patch to solve the problem. But is there a simple way to make DHCP client work on
eth0.0? Or there exists any other trick to use 802.1p without setting up VLAN?
The following thread seems to indicate it's a known problem on Linux VLAN:
Thanks in advance!
