Is there any way to build a firewall rule to block PPPoE discovey broadcasts?

Ethertype = 8863 (PPPoE Discovery)

Use bridge firewall in "/interface bridge firewall" menu

Eugene:

would it be possible to have the ability to match pppoe specific packet fields added to bridge filter?
Move along. Nothing to see here.

You probably need to give more info on your config and what you are trying to achieve. PPPoE discovery broadcasts are not forwarded/routed at layer 3.

The 0.0.0.0 traffic could be PPPoE session traffic. Which MAC protocol does it show?

The 8864 traffic looks like PPPoE session traffic. From your original question I can't tell what seems unusual about it.
