8 depends on (PCI || EISA || CARDBUS)
10 This selects the "Tulip" family of EISA/PCI network cards.
15 tristate "Early DECchip Tulip (dc2104x) PCI support"
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

31 int "Descriptor Skip Length in 32 bit longwords"
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.
43 tristate "DECchip Tulip (dc2114x) PCI support"
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

59 bool "New bus configuration"
62 This configures your Tulip card specifically for the card and
63 system cache line size type you are using.
65 This is experimental code, not yet tested on many boards.
70 bool "Use PCI shared mem for NIC registers"
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.
79 bool "Use RX polling (NAPI)"
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.
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),
92 config TULIP_NAPI_HW_MITIGATION
93 bool "Use Interrupt Mitigation"
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

108 tristate "Generic DECchip & DIGITAL EtherWORKS PCI/EISA"
109 depends on (PCI || EISA)
110 depends on VIRT_TO_BUS || ALPHA || PPC || SPARC
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
116 information is contained in
117 <file:Documentation/networking/device_drivers/ethernet/dec/de4x5.rst>.

123 tristate "Winbond W89c840 Ethernet support"
128 This driver is for the Winbond W89c840 chip. It also works with
129 the TX9882 chip on the Compex RL100-ATX board.
130 More specific information and updates are available from
131 <http://www.scyld.com/network/drivers.html>.
134 tristate "Davicom DM910x/DM980x support"
138 This driver is for DM9102(A)/DM9132/DM9801 compatible PCI cards from
139 Davicom (<http://www.davicom.com.tw/>). If you have such a network
140 (Ethernet) card, say Y. Some information is contained in the file

158 tristate "Xircom CardBus support"
161 This driver is for the Digital "Tulip" Ethernet CardBus adapters.
162 It should work with most DEC 21*4*-based chips/ethercards, as well
163 as with work-alike chips from Lite-On (PNIC) and Macronix (MXIC) and
166 To compile this driver as a module, choose M here. The module will
167 be called xircom_cb. If unsure, say N.
