Current bridge fdb update code does not seem to update the port
during fdb update. This patch adds a check for fdb dst (port)
change during fdb update. Also rearranges the call to
fdb_notify to send only one notification for create and update.
Changelog:
v2 - Change notify flag to bool

This needs review and is just rotting in my patchwork backlog.
Please someone with bridge knowledge take a look at this patch.
Thanks.

Ok, if nobody with bridgining expertiece can be bothered to review
this I'm simply not going to apply it, it must not be that important.

The patch fixes a real oversight in the forwarding database management stuff.
A couple of minor tweaks.
1. Always update used value but don't change 'updated' value unless changed.
2. Rename notify flag to modified
3. Add some whitespace.
