Re: VLAN patches

[Eran Mann <emann@mrv.com>]

According to 802.1Q (which is BTW available freely from IEEE's site) 
0xFFF VID is "Reserved for implementation use. This VID value shall not 
be configured as a PVID, configured in any Filtering Database entry, 
used in any Management operation, or transmitted in a tag header.".

Regarding the 0 VID it is indeed used for priority-only frames. 
Shouldn't it be supported by alowing the user to configure a priority 
map for the ethernet device (rather than creating another user-visible 
device?
