The examples page at sourceforge shows how to use ebtables to avoid
spoofing:

ebtables -A FORWARD -p IPv4 --ip-src 172.16.1.4 -s ! 00:11:22:33:44:55 -j DROP

I'd like to do the same but all frames here are tagged, which makes
ebtables see them as type 0x8100 and not as IPv4. Therefore the rule
never matches and frames are not dropped.

Is there a way to do anti-spoof with ebtables and tagged frames?
