I am still using the multicast loss (plus the raw link speed) to judge
the links, but I have done some early experiments with integrating the
L2 frame statistics too. Not sure it works that well for wifi without
a lot of probing, much more than you need for getting an useful link
speed).

Multipoint Relays. Its a method to reduce the flooding overhead in a
wireless mesh network. Its defined in RFC 7181, but its a modification
of NHDP so I put it into my NHDP implementation.

With an Atheros card I get both transmitted frames, retransmitted
frames and (completely) lost frames on the sender side of a link...
its just that these values are not that useful when most of your
wireless links are not transporting traffic.
