 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.) Do read the Ethernet-HOWTO, available from
 25           <http://www.tldp.org/docs.html#howto>.

 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.

 59 config TULIP_MWI
 60         bool "New bus configuration"
 61         depends on TULIP
 62         ---help---
 63           This configures your Tulip card specifically for the card and
 64           system cache line size type you are using.
 65 
 66           This is experimental code, not yet tested on many boards.
 67 
 68           If unsure, say N.

 71         bool "Use PCI shared mem for NIC registers"
 72         depends on TULIP
 73         ---help---
 74           Use PCI shared memory for the NIC registers, rather than going through
 75           the Tulip's PIO (programmed I/O ports).  Faster, but could produce
 76           obscure bugs if your mainboard has memory controller timing issues.
 77           If in doubt, say N.
 78 
 79 config TULIP_NAPI
 80         bool "Use RX polling (NAPI)"
 81         depends on TULIP
 82         ---help---
 83           NAPI is a new driver API designed to reduce CPU and interrupt load
 84           when the driver is receiving lots of packets from the card. It is
 85           still somewhat experimental and thus not yet enabled by default.
 86 
 87           If your estimated Rx load is 10kpps or more, or if the card will be
 88           deployed on potentially unfriendly networks (e.g. in a firewall),
 89           then say Y here.
 90 
 91           If in doubt, say N.

 95         depends on TULIP_NAPI
 96         ---help---
 97           Use HW to reduce RX interrupts. Not strictly necessary since NAPI
 98           reduces RX interrupts by itself. Interrupt mitigation reduces RX
 99           interrupts even at low levels of traffic at the cost of a small
100           latency.
101 
102           If in doubt, say Y.

115           These include the DE425, DE434, DE435, DE450 and DE500 models.  If
116           you have a network card of this type, say Y and read the
117           Ethernet-HOWTO, available from
118           <http://www.tldp.org/docs.html#howto>. More specific
119           information is contained in

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

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