Having the current count is just a helper, if you have a high limit dumping the table
and counting might take awhile. Thanks for the feedback, then we'll polish and move
on with the set for a global limit.

Ok, but to be useful, the current count will have to be directly
comparable to the limit, I guess. So the current count will also be for
dynamically learned entries? Or is the plan to enforce the global limit
for any kind of FDB entries?

That was one of the questions actually. More that I'm thinking about this, the more
I want to break it apart by type because we discussed being able to specify a flag
mask for the limit (all, dynamic, dynamic+static etc). If we embed these stats into a
bridge fdb count attribute, it can be easily extended later if anything new comes along.
If switchdev doesn't support some of these global limit configs, we can pass the option
and it can deny setting it later. I think this should be more than enough as a first step.
