AF_PACKET is the only user of this private field, and
I want people to be aware of this and not try to use it
for other stuff.

Nobody else can use it for something different, the code
in net/core/dev.c does specific things when it's non-NULL
knowing that this non-NULL value means that it's an
AF_PACKET packet_type being passed to it.

So we won't make your suggested change.
