Add a configurable Descriptor Skip Length for systems that lack cache coherence.

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"

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.

This configures your Tulip card specifically for the card and

system cache line size type you are using.

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.

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.

---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.
