This?module?implements?the?Advanced?Micro?Devices?Am79C971
Am79C972?and?Am79C973?PCnet-PCI?Ethernet?32?bit?network?interface?driver.

The?PCnet-PCI?ethernet?controller?is?inherently?little?endian?because
the?chip?is?designed?to?operate?on?a?PCI?bus?which?is?a?little?endian
bus.?The?software?interface?to?the?driver?is?divided?into?three?parts.
The?first?part?is?the?PCI?configuration?registers?and?their?set?up.?
This?part?is?done?at?the?BSP?level?in?the?various?BSPs?which?use?this
driver.?The?second?and?third?part?are?dealt?in?the?driver.?The?second
part?of?the?interface?comprises?of?the?I/O?control?registers?and?their
programming.?The?third?part?of?the?interface?comprises?of?the?descriptors
and?the?buffers.?

This?driver?is?designed?to?be?moderately?generic?operating?unmodified
across?the?range?of?architectures?and?targets?supported?by?VxWorks.??To
achieve?this?the?driver?must?be?given?several?target-specific?parameters
and?some?external?support?routines?must?be?provided.?These?target-specific
values?and?the?external?support?routines?are?described?below.

This?driver?supports?multiple?units?per?CPU.??The?driver?can?be
configured?to?support?big-endian?or?little-endian?architectures.??It
contains?error?recovery?code?to?handle?known?device?errata?related?to?DMA
activity.?

Big?endian?processors?can?be?connected?to?the?PCI?bus?through?some?controllers
which?take?care?of?hardware?byte?swapping.?In?such?cases?all?the?registers?
which?the?chip?DMA?s?to?have?to?be?swapped?and?written?to?so?that?when?the
hardware?swaps?the?accesses?the?chip?would?see?them?correctly.?The?chip?still
has?to?be?programmed?to?operated?in?little?endian?mode?as?it?is?on?the?PCI?bus.
If?the?cpu?board?hardware?automatically?swaps?all?the?accesses?to?and?from?the
PCI?bus?then?input?and?output?byte?stream?need?not?be?swapped.?

BOARD?LAYOUT
This?device?is?on-board.??No?jumpering?diagram?is?necessary.

EXTERNAL?INTERFACE
The?only?external?interface?is?the?ln97xEndLoad（）?routine?which?expects
the??parameter?as?input.??This?parameter?passes?in?a?
colon-delimited?string?of?the?format:

:::se::::
::::

The?ln97xEndLoad（）?function?uses?strtok（）?to?parse?the?string.

TARGET-SPECIFIC?PARAMETERS
.IP?
A?convenient?holdover?from?the?former?model.??This?parameter?is?used?only
in?the?string?name?for?the?driver.

.IP?
This?parameter?in?the?memory?base?address?of?the?device?registers?in?the
memory?map?of?the?CPU.?It?indicates?to?the?drive
