 17	select CRC32
 18	help
 19	  This driver is developed for the SMC EtherPower series Ethernet
 20	  cards and also works with cards based on the DECchip
 21	  21040 (Tulip series) chips.  Some LinkSys PCI cards are
 22	  of this type.  (If your card is NOT SMC EtherPower 10/100 PCI
 23	  (smc9332dst), you can also try the driver for "Generic DECchip"
 24	  cards, below.  However, most people with a network card of this type
 25	  will say Y here.)

 31	int "Descriptor Skip Length in 32 bit longwords"

 33	range 0 31
 34	default 0
 35	help
 36	  Setting this value allows to align ring buffer descriptors into their
 37	  own cache lines. Value of 4 corresponds to the typical 32 byte line
 38	  (the descriptor is 16 bytes). This is necessary on systems that lack
 39	  cache coherence, an example is PowerMac 5500. Otherwise 0 is safe.
 40	  Default is 0, and range is 0 to 31.

 46	help
 47	  This driver is developed for the SMC EtherPower series Ethernet
 48	  cards and also works with cards based on the DECchip 
 49	  21140 (Tulip series) chips.  Some LinkSys PCI cards are

 58config TULIP_MWI
 59	bool "New bus configuration"
 60	depends on TULIP
 61	help
 62	  This configures your Tulip card specifically for the card and
 63	  system cache line size type you are using.
 64
 65	  This is experimental code, not yet tested on many boards.
 66
 67	  If unsure, say N.
 68
 69config TULIP_MMIO
 70	bool "Use PCI shared mem for NIC registers"
 71	depends on TULIP
 72	help
 73	  Use PCI shared memory for the NIC registers, rather than going through
 74	  the Tulip's PIO (programmed I/O ports).  Faster, but could produce
 75	  obscure bugs if your mainboard has memory controller timing issues.
 76	  If in doubt, say N.
 77
 78config TULIP_NAPI
 79	bool "Use RX polling (NAPI)"
 80	depends on TULIP
 81	help
 82	  NAPI is a new driver API designed to reduce CPU and interrupt load
 83	  when the driver is receiving lots of packets from the card. It is
 84	  still somewhat experimental and thus not yet enabled by default.
 85
 86	  If your estimated Rx load is 10kpps or more, or if the card will be
 87	  deployed on potentially unfriendly networks (e.g. in a firewall),
 88	  then say Y here.
 89
 90	  If in doubt, say N.
 91
 92config TULIP_NAPI_HW_MITIGATION
 93	bool "Use Interrupt Mitigation"
 94	depends on TULIP_NAPI
 95	help
 96	  Use HW to reduce RX interrupts. Not strictly necessary since NAPI
 97	  reduces RX interrupts by itself. Interrupt mitigation reduces RX
 98	  interrupts even at low levels of traffic at the cost of a small
 99	  latency.
100
101	  If in doubt, say Y.

123	  This driver is for DM9102(A)/DM9132/DM9801 compatible PCI cards from
124	  Davicom (<http://www.davicom.com.tw/>).  If you have such a network
125	  (Ethernet) card, say Y.  Some information is contained in the file

146	  This driver is for the Digital "Tulip" Ethernet CardBus adapters.
147	  It should work with most DEC 21*4*-based chips/ethercards, as well
148	  as with work-alike chips from Lite-On (PNIC) and Macronix (MXIC) and
149	  ASIX.
