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
eth0.0:

    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!
