	Would returning -EOPNOTSUPP be more appropriate?

I don't think that would be so good, as the command

bridge fdb replace ADDR dev <DEV> master dynamic

is a valid command and should not generate errors. When ignored by the 
driver, it will just install a dynamic FDB entry in the bridge, and the 
bridge will age it.

Sure, I agree that it's not necessarily an error that needs
to propagate to the user.

My assumption, which I now see is likely false, is that drivers
could return -EOPNOTSUPP, to indicate to higher layers that the operation
is not supported. But the higher layers may not propagate that.

But it seems that is not the case here. So I think return 0 is fine
after all. Sorry for the noise.

No noise at all... I think your concern is quite ligitimate. With this 
flag there is no iproute2 changes, so not to change behaviour of old 
commands the best is to ignore silently. But I have another flag coming 
up that will be accomodated with a new iproute2 command, and then your 
suggestion is more appropriate. The question will then be if the returns 
for that flag should be -EOPNOTSUPP.
