 25	  This is a network (Ethernet) device which attaches to your parallel
 26	  port. Read the file <file:drivers/net/ethernet/realtek/atp.c>
 27	  if you want to use this.  If you intend to use this driver, you
 28	  should have said N to the "Parallel printer support", because the two
 29	  drivers don't like each other.

 31	  To compile this driver as a module, choose M here: the module
 32	  will be called atp.

 38	select MII
 39	help
 40	  This is a driver for the Fast Ethernet PCI network cards based on
 41	  the RTL8139C+ chips. If you have one of those, say Y here.
 42
 43	  To compile this driver as a module, choose M here: the module
 44	  will be called 8139cp.  This is recommended.

 52	  This is a driver for the Fast Ethernet PCI network cards based on
 53	  the RTL 8129/8130/8139 chips. If you have one of those, say Y here.
 54
 55	  To compile this driver as a module, choose M here: the module

 59	bool "Use PIO instead of MMIO"
 60	default y
 61	depends on 8139TOO
 62	help
 63	  This instructs the driver to use programmed I/O ports (PIO) instead
 64	  of PCI shared memory (MMIO).  This can possibly solve some problems
 65	  in case your mainboard has memory consistency issues.  If unsure,
 66	  say N.
 67
 68config 8139TOO_TUNE_TWISTER
 69	bool "Support for uncommon RTL-8139 rev. K (automatic channel equalization)"
 70	depends on 8139TOO
 71	help
 72	  This implements a function which might come in handy in case you
 73	  are using low quality on long cabling. It is required for RealTek
 74	  RTL-8139 revision K boards, and totally unused otherwise.  It tries
 75	  to match the transceiver to the cable characteristics. This is
 76	  experimental since hardly documented by the manufacturer.
 77	  If unsure, say Y.
 78
 79config 8139TOO_8129
 80	bool "Support for older RTL-8129/8130 boards"
 81	depends on 8139TOO
 82	help
 83	  This enables support for the older and uncommon RTL-8129 and
 84	  RTL-8130 chips, which support MII via an external transceiver,
 85	  instead of an internal one.  Disabling this option will save some
 86	  memory by making the code size smaller.  If unsure, say Y.
 87
 88config 8139_OLD_RX_RESET
 89	bool "Use older RX-reset method"
 90	depends on 8139TOO
 91	help
 92	  The 8139too driver was recently updated to contain a more rapid
 93	  reset sequence, in the face of severe receive errors.  This "new"
 94	  RX-reset method should be adequate for all boards.  But if you
 95	  experience problems, you can enable this option to restore the
 96	  old RX-reset behavior.  If unsure, say N.

107	  the following families:
108	  RTL8169 Gigabit Ethernet
109	  RTL8168 Gigabit Ethernet
110	  RTL8101 Fast Ethernet
