Just to clarify for myself. I expect that with just the helpers here
we should only expect static configurations to work, e.g. any learning
and/or aging is not likely to work if we do redirects in the XDP path.

As you described above, learning and aging don’t work at this point. 

IMO, another helper for learning will be required to fill the requirements.
I guess that the helper will enable us to use the aging feature as well
because the aging is the functionality of bridge fdb.

One option is to have a flag that bumps the ageing on successful lookup
and do that in 1 call. You will already have access to the fdb entry.

It seems like a good idea to me! I guess that the flags in my suggested bpf
helper for the FDB lookup will be useful for such a case.

Thanks & Best regards,
