In a future patch HAS_IOPORT=n will disable inb()/outb() and friends at compile time. 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.

Arcnet configuration
menuconfig ARCNET depends on NETDEVICES && (ISA || PCI || PCMCIA) && HAS_IOPORT tristate "ARCnet support" help If you have a network card of this type, say Y and check out the (arguably) beautiful poetry in file:Documentation/networking/arcnet.rst.
You need both this driver, and the driver for the particular ARCnet
chipset of your card. If you don't know, then it's probably a
COM90xx type card, so say Y (or M) to "ARCnet COM90xx chipset
support" below.
To compile this driver as a module, choose M here. The module will
be called arcnet.
if ARCNET
config ARCNET_1201 tristate "Enable standard ARCNet packet format (RFC 1201)" help This allows you to use RFC1201 with your ARCnet card via the virtual arc0 device. You need to say Y here to communicate with industry-standard RFC1201 implementations, like the arcether.com packet driver or most DOS/Windows ODI drivers. Please read the ARCnet documentation in file:Documentation/networking/arcnet.rst for more information about using arc0.
config ARCNET_1051 tristate "Enable old ARCNet packet format (RFC 1051)" help This allows you to use RFC1051 with your ARCnet card via the virtual arc0s device. You only need arc0s if you want to talk to ARCnet software complying with the "old" standard, specifically, the DOS arcnet.com packet driver, Amigas running AmiTCP, and some variants of NetBSD. You do not need to say Y here to communicate with industry-standard RFC1201 implementations, like the arcether.com packet driver or most DOS/Windows ODI drivers. RFC1201 is included automatically as the arc0 device. Please read the ARCnet documentation in file:Documentation/networking/arcnet.rst for more information about using arc0e and arc0s.
config ARCNET_RAW tristate "Enable raw mode packet interface" help ARCnet "raw mode" packet encapsulation, no soft headers. Unlikely to work unless talking to a copy of the same Linux arcnet driver, but perhaps marginally faster in that case.
config ARCNET_CAP tristate "Enable CAP mode packet interface" help ARCnet "cap mode" packet encapsulation. Used to get the hardware acknowledge back to userspace. After the initial protocol byte every packet is stuffed with an extra 4 byte "cookie" which doesn't actually appear on the network. After transmit the driver will send back a packet with protocol byte 0 containing the status of the transmission: 0=no hardware acknowledge 1=excessive nak 2=transmission accepted by the receiver hardware
Received packets are also stuffed with the extra 4 bytes but it will
be random data.
Cap only listens to protocol 1-8.
config ARCNET_COM90xx tristate "ARCnet COM90xx (normal) chipset driver" help This is the chipset driver for the standard COM90xx cards. If you have always used the old ARCnet driver without knowing what type of card you had, this is probably the one for you.
To compile this driver as a module, choose M here. The module will
be called com90xx.
config ARCNET_COM90xxIO tristate "ARCnet COM90xx (IO mapped) chipset driver" help This is the chipset driver for the COM90xx cards, using them in IO-mapped mode instead of memory-mapped mode. This is slower than the normal driver. Only use it if your card doesn't support shared memory.
To compile this driver as a module, choose M here. The module will
be called com90io.
config ARCNET_RIM_I tristate "ARCnet COM90xx (RIM I) chipset driver" help This is yet another chipset driver for the COM90xx cards, but this time only using memory-mapped mode, and no IO ports at all. This driver is completely untested, so if you have one of these cards, please mail dwmw2@infradead.org, especially if it works!
To compile this driver as a module, choose M here. The module will
be called arc-rimi.
config ARCNET_COM20020 tristate "ARCnet COM20020 chipset driver" depends on LEDS_CLASS help This is the driver for the new COM20020 chipset. It supports such things as promiscuous mode, so packet sniffing is possible, and extra diagnostic information.
To compile this driver as a module, choose M here. The module will
be called com20020.
config ARCNET_COM20020_ISA tristate "Support for COM20020 on ISA" depends on ARCNET_COM20020 && ISA
config ARCNET_COM20020_PCI tristate "Support for COM20020 on PCI" depends on ARCNET_COM20020 && PCI
config ARCNET_COM20020_CS tristate "COM20020 ARCnet PCMCIA support" depends on ARCNET_COM20020 && PCMCIA help Say Y here if you intend to attach this type of ARCnet PCMCIA card to your computer.
To compile this driver as a module, choose M here: the module will be
called com20020_cs. If unsure, say N.
