TBH, this does change a user facing api (the attribute nesting), but I think
in this case it's acceptable due to the format being wrong and MRP being new, so
I doubt anyone is yet dumping it mixed with vlan filter_mask and checking for
two identical attributes, i.e. in the old/broken case parsing the attributes
into a table would hide one of them and you'd have to walk over all attributes
to catch that.
