[PATCH v5 22/44] net: handle HAS_IOPORT dependencies

Niklas Schnelle
2023-05-22T10:54:38Z

In a future patch HAS_IOPORT=n will result in inb()/outb() and friends
not being declared. We thus need to add HAS_IOPORT as dependency for
those drivers requiring them. For the DEFXX driver the use of I/O
ports is optional and we only need to fence specific code paths. It also
turns out that with HAS_IOPORT handled explicitly HAMRADIO does not need
the !S390 dependency and successfully builds the bpqether driver.
