FireQOS matching by MAC address

It would be nice to be able to create a “match” rule in FireQOS to match traffic by MAC address.

I’m interested in this because we’ll be transitioning to a dual-stack network with both IPv4 and IPv6 support. Currently, we assign IPv4 addresses using DHCP (some are assigned fixed addresses, and others put into different pools), then in fireqos.conf classify using “match src” and “match dst” rules with IP addresses. I know this isn’t bulletproof, but since I control all of the hosts, it works. With IPv6, we'll get a /64 address from our ISP, which can’t be subnetted further, and I suppose we’ll be using SLAAC instead of DHCP (haven’t sorted that out yet). So, the only way I can think of to do traffic classification on a per-host basis is using the MAC address.

Anything I’m missing?
