Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

config NET_VENDOR_SMSC
	bool "SMC (SMSC)/Western Digital devices"
	default y
	depends on ARM || ARM64 || ATARI_ETHERNAT || COLDFIRE || \

	help
	  If you have a network (Ethernet) card belonging to this class, say Y.

	  Note that the answer to this question doesn't directly affect the
	  kernel: saying N will just cause the configurator to skip all
	  the questions about SMC/Western Digital cards. If you say Y, you will
	  be asked for your specific card in the following questions.

if NET_VENDOR_SMSC

	help
	  This is a driver for SMC's 91x series of Ethernet chipsets,
	  including the SMC91C94 and the SMC91C111. Say Y if you want it
	  compiled into the kernel, and read the file
	  <file:Documentation/networking/device_drivers/ethernet/smsc/smc9.rst>.

	  This driver is also available as a module ( = code which can be
	  inserted in and removed from the running kernel whenever you want).
	  The module will be called smc91x.  If you want to compile it as a
	  module, say M here and read <file:Documentation/kbuild/modules.rst>.

config EPIC100
	tristate "SMC EtherPower II"
	depends on PCI
	select CRC32
	select MII
	help
	  This driver is for the SMC EtherPower II 9432 PCI Ethernet NIC,
	  which is based on the SMC83c17x (EPIC/100).
	  More specific information and updates are available from
	  <http://www.scyld.com/network/epic100.html>.

config SMSC911X
	tristate "SMSC LAN911x/LAN921x families embedded ethernet support"
	depends on HAS_IOMEM
	select CRC32
	select MII
	select PHYLIB
	help
	  Say Y here if you want support for SMSC LAN911x and LAN921x families
	  of ethernet controllers.

	  To compile this driver as a module, choose M here. The module
	  will be called smsc911x.

config SMSC911X_ARCH_HOOKS
	def_bool n
	depends on SMSC911X
	help
	  If the arch enables this, it allows the arch to implement various
	  hooks for more comprehensive interrupt control and also to override
	  the source of the MAC address.
