Risto Suominen b77e522884 de2104x: support for systems lacking cache coherence
Add a configurable Descriptor Skip Length for systems that lack cache
coherence.

(akpm: I think this should be done as a module parameter, not a
compile-tinme option)

# Tulip family network device configuration

menuconfig NET_TULIP
bool "\"Tulip\" family network device support"
depends on PCI || EISA || CARDBUS
help
This selects the "Tulip" family of EISA/PCI network cards.
if NET_TULIP
config DE2104X
tristate "Early DECchip Tulip (dc2104x) PCI support (EXPERIMENTAL)"
depends on PCI && EXPERIMENTAL
select CRC32
---help---
This driver is developed for the SMC EtherPower series Ethernet
cards and also works with cards based on the DECchip
21040 (Tulip series) chips. Some LinkSys PCI cards are
of this type. (If your card is NOT SMC EtherPower 10/100 PCI
(smc9332dst), you can also try the driver for "Generic DECchip"
cards, below. However, most people with a network card of this type
will say Y here.) Do read the Ethernet-HOWTO, available from
<http://www.tldp.org/docs.html#howto>.
To compile this driver as a module, choose M here. The module will
be called de2104x.
config DE2104X_DSL
int "Descriptor Skip Length in 32 bit longwords"
depends on DE2104X
range 0 31
default 0
help
Setting this value allows to align ring buffer descriptors into their
own cache lines. Value of 4 corresponds to the typical 32 byte line
(the descriptor is 16 bytes). This is necessary on systems that lack
cache coherence, an example is PowerMac 5500. Otherwise 0 is safe.
Default is 0, and range is 0 to 31.
config TULIP
tristate "DECchip Tulip (dc2114x) PCI support"
depends on PCI
select CRC32
---help---
This driver is developed for the SMC EtherPower series Ethernet
cards and also works with cards based on the DECchip
21140 (Tulip series) chips. Some LinkSys PCI cards are
of this type. (If your card is NOT SMC EtherPower 10/100 PCI
(smc9332dst), you can also try the driver for "Generic DECchip"
cards, above. However, most people with a network card of this type
will say Y here.) Do read the Ethernet-HOWTO, available from
<http://www.tldp.org/docs.html#howto>.
To compile this driver as a module, choose M here. The module will
be called tulip.
config TULIP_MWI
bool "New bus configuration (EXPERIMENTAL)"
depends on TULIP && EXPERIMENTAL
help
This configures your Tulip card specifically for the card and
system cache line size type you are using.
This is experimental code, not yet tested on many boards.
If unsure, say N.
config TULIP_MMIO
bool "Use PCI shared mem for NIC registers"
depends on TULIP
help
Use PCI shared memory for the NIC registers, rather than going through
the Tulip's PIO (programmed I/O ports). Faster, but could produce
obscure bugs if your mainboard has memory controller timing issues.
If in doubt, say N.
config TULIP_NAPI
bool "Use RX polling (NAPI)"
depends on TULIP
help
NAPI is a new driver API designed to reduce CPU and interrupt load
when the driver is receiving lots of packets from the card. It is
still somewhat experimental and thus not yet enabled by default.
If your estimated Rx load is 10kpps or more, or if the card will be
deployed on potentially unfriendly networks (e.g. in a firewall),
then say Y here.
If in doubt, say N.
config TULIP_NAPI_HW_MITIGATION
bool "Use Interrupt Mitigation"
depends on TULIP_NAPI
---help---
Use HW to reduce RX interrupts. Not strictly necessary since NAPI
reduces RX interrupts by itself. Interrupt mitigation reduces RX
interrupts even at low levels of traffic at the cost of a small
latency.
If in doubt, say Y.
config DE4X5
tristate "Generic DECchip & DIGITAL EtherWORKS PCI/EISA"
depends on PCI || EISA
select CRC32
---help---
This is support for the DIGITAL series of PCI/EISA Ethernet cards.
These include the DE425, DE434, DE435, DE450 and DE500 models. If
you have a network card of this type, say Y and read the
Ethernet-HOWTO, available from
<http://www.tldp.org/docs.html#howto>. More specific
information is contained in
<file:Documentation/networking/de4x5.txt>.
To compile this driver as a module, choose M here. The module will
be called de4x5.
config WINBOND_840
tristate "Winbond W89c840 Ethernet support"
depends on PCI
select CRC32
select MII
help
This driver is for the Winbond W89c840 chip. It also works with
the TX9882 chip on the Compex RL100-ATX board.
More specific information and updates are available from
<http://www.scyld.com/network/drivers.html>.
config DM9102
tristate "Davicom DM910x/DM980x support"
depends on PCI
select CRC32
---help---
This driver is for DM9102(A)/DM9132/DM9801 compatible PCI cards from
Davicom (<http://www.davicom.com.tw/>). If you have such a network
(Ethernet) card, say Y. Some information is contained in the file
<file:Documentation/networking/dmfe.txt>.
To compile this driver as a module, choose M here. The module will
be called dmfe.
config ULI526X
tristate "ULi M526x controller support"
depends on PCI
select CRC32
---help---
This driver is for ULi M5261/M5263 10/100M Ethernet Controller
(<http://www.uli.com.tw/>).
To compile this driver as a module, choose M here. The module will
be called uli526x.
config PCMCIA_XIRCOM
tristate "Xircom CardBus support"
depends on CARDBUS
---help---
This driver is for the Digital "Tulip" Ethernet CardBus adapters.
It should work with most DEC 21*4*-based chips/ethercards, as well
as with work-alike chips from Lite-On (PNIC) and Macronix (MXIC) and
ASIX.
To compile this driver as a module, choose M here. The module will
be called xircom_cb. If unsure, say N.
