hi,
so as nobody likes the magic numbers, and we already have a handshake in 
between the dataplane and the control plane,
i got the idea that what if the bffwd would tell freerouter all the remaining 
mapping of the export-port parameters,
like fec, autoneg and flwctrl? then the netadmin would be able to use the 
names much like it's already happening with
the front-panel port names? here is the small change implementing the above:
https://github.com/rare-freertr/freeRtr/commit/7ffaa39864c0eb54fa546bb630337fab5dc60d7c
the drawback of this commit is the additional complexity in case of gearboxed 
switches like the
bf2556tx where these magics need to be translated to the gearbox values in 
case of gearbox ports...
ps: alex, as you're the only one access to a tofino2, could you please verify 
if these are the right values on 400g too?
ps2: could someone please populate the flow control table in bffwd? :)
thanks,
cs
