Filter granularity

I’d like to see some more granularity in how customer traffic filtering is done. Say a table like choose what level of filtering, and then allow the user to choose from a list or enter the values manually.

For example, since I use PPPoE on my network, if I could tell the SMs to drop all traffic that wasn’t ethertype 0x8863 or 0x8864, I could rest 100% certain that the other stuff is going to be stopped, unlike the current method.
