To compile the actual ethernet driver, choose Y or M for the SMC91X
option in the network device section; the module will be called smc91x.
config ATARI_ETHERNEC
bool "Atari EtherNEC Ethernet support"
depends on ATARI_ROM_ISA
---help---
Say Y to include support for the EtherNEC network adapter for the
ROM port. The driver works by polling instead of interrupts, so it
is quite slow.
This driver also suppports the ethernet part of the NetUSBee ROM
port combined Ethernet/USB adapter.
To compile the actual ethernet driver, choose Y or M in for the NE2000
option in the network device section; the module will be called ne.
