net: Fix remaining API interface breakage

These are all the files which use the API incorrectly but did not get
built using MAKEALL -a powerpc|arm.  I have no compiler for them, but
the remaining issues should be far less than without this patch.

Any outstanding issues are left to the maintainers of boards that use
these drivers.
