Subject: Re: Regarding vlan ingress filtering in linux

Hi,
Thanks for the reply.

I have following 4 different and independent requirements. How can I achieve this???

1.) There is no vlan on eth0 and I want any vlan tagged traffic on eth0 should not be processed.

2.) There is no vlan on eth0 and I want any vlan tagged traffic on eth0 should be processed as if it doesn't have any tag.

3.)
 There is vlan 10 on eth0 with inteface name as eth0.10. If there is any
 untagged traffic on eth0, it should be processed as if it belongs to 
vlan10.

4.) There is vlan 10 on eth0 with inteface name as eth0.10. If there is any 
untagged traffic on eth0, it should not be processed.

Any help will be highly appreciated?

Thanks and Regards,
-Akshat

Hi,
If you are talking about disabling or setting rx vlan filter
offloading parameter, the latest ethtool (from git) has this:

./ethtool -k p2p1
....
rx-vlan-filter: off [fixed]
....

But it seems to me that in order to set it (by "ethtool -K p2p1
rx-vlan-filter on") you need special support
from the device driver.

regards,
Rami Rosen
