this is a case in point for one of my previous comments...

this code started out believing that testing for mtk_netsys_v2 for v2
features would be sufficient. your first patch ended up having to
change that to !v1. how long until this becomes !v1 && !v2 because
it gets used on v3 and v4 etc?

this is why i think an integer version field would be a much saner
approach.
