Need to bridge 802.1x MAC 01:80:c2:00:00:03

RouterOS General
1

In Linux I can set

echo 8 > /sys/class/net/br0/bridge/group_fwd_mask
To allow non 802.1D traffic to be bridged in a bridge group. 802.1D is not suppose to bridge 01:80:c2:00:00:00 to 01:80:c2:00:00:0f

I need to bridge 01:80:c2:00:00:03 traffic so I can bypass my stupid Uverse box session limits.

The rest I do with ebtables type things which I believe I can figure out in Mikrotik.

Here is the webpage I am reviewing to convert to Mikrotik Format.

Any help would be appreciated.

Thanks
