 17         ---help---
 18           This driver is developed for the SMC EtherPower series Ethernet
 19           cards and also works with cards based on the DECchip
 20           21040 (Tulip series) chips.  Some LinkSys PCI cards are
 21           of this type.  (If your card is NOT SMC EtherPower 10/100 PCI
 22           (smc9332dst), you can also try the driver for "Generic DECchip"
 23           cards, below.  However, most people with a network card of this type
 24           will say Y here.)
 25 
 26           To compile this driver as a module, choose M here. The module will
 27           be called de2104x.

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

 57 config TULIP_MWI
 58         bool "New bus configuration"
 59         depends on TULIP
 60         ---help---
 61           This configures your Tulip card specifically for the card and
 62           system cache line size type you are using.
 63 
 64           This is experimental code, not yet tested on many boards.
 65 
 66           If unsure, say N.

 68 config TULIP_MMIO
 69         bool "Use PCI shared mem for NIC registers"
 70         depends on TULIP
 71         ---help---
 72           Use PCI shared memory for the NIC registers, rather than going through
 73           the Tulip's PIO (programmed I/O ports).  Faster, but could produce
 74           obscure bugs if your mainboard has memory controller timing issues.
 75           If in doubt, say N.
 76 
 77 config TULIP_NAPI
 78         bool "Use RX polling (NAPI)"
 79         depends on TULIP
 80         ---help---
 81           NAPI is a new driver API designed to reduce CPU and interrupt load
 82           when the driver is receiving lots of packets from the card. It is
 83           still somewhat experimental and thus not yet enabled by default.
 84 
 85           If your estimated Rx load is 10kpps or more, or if the card will be
 86           deployed on potentially unfriendly networks (e.g. in a firewall),
 87           then say Y here.
 88 
 89           If in doubt, say N.

 92         bool "Use Interrupt Mitigation"
 93         depends on TULIP_NAPI
 94         ---help---
 95           Use HW to reduce RX interrupts. Not strictly necessary since NAPI
 96           reduces RX interrupts by itself. Interrupt mitigation reduces RX
 97           interrupts even at low levels of traffic at the cost of a small
 98           latency.
 99 
100           If in doubt, say Y.

113           These include the DE425, DE434, DE435, DE450 and DE500 models.  If
114           you have a network card of this type, say Y.  More specific
115           information is contained in

138           Davicom (<http://www.davicom.com.tw/>).  If you have such a network
139           (Ethernet) card, say Y.  Some information is contained in the file

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