16	depends on PCI
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"
32	depends on DE2104X
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
50	  of this type.  (If your card is NOT SMC EtherPower 10/100 PCI

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.

113	  This is support for the DIGITAL series of PCI/EISA Ethernet cards.
114	  These include the DE425, DE434, DE435, DE450 and DE500 models.  If
115	  you have a network card of this type, say Y.  More specific

161	  This driver is for the Digital "Tulip" Ethernet CardBus adapters.
