/proc/net/vlan/config output patch and question

[Norbert Kiesel <nkiesel@xxxxxxxxxxxxxxx>]

Hi,

when creating a VLAN device, I end up with names like
"vlan8_rename@eth0" when using VLAN_NAME_TYPE_PLUS_VID_NO_PAD.  Other
formats have that "_rename" appended as well. Any idea where that comes
from? I'm running a stock 2.6.20.4 kernel on Debian unstable using
vconfig from vlan-1.9-2.  I checked the vconfig sources but these don't
contain the _rename AFAICS.

Another thing I noticed was the slightly confusing output of
"cat /proc/net/vlan/config".  I append a patch that I think improves
that, though I don't know if there are tools parsing that output.

Best,
  Norbert
