When I removed net-modules.txt because it only contained ancient information I missed that many Kconfig entries pointed to this ancient information. Signed-off-by: Adrian Bunk <bunk@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>

The 3Com Etherlink Plus (3c505) driver.
|
|
|
|
This driver now uses DMA. There is currently no support for PIO operation.
|
|
The default DMA channel is 6; this is _not_ autoprobed, so you must
|
|
make sure you configure it correctly. If loading the driver as a
|
|
module, you can do this with "modprobe 3c505 dma=n". If the driver is
|
|
linked statically into the kernel, you must either use an "ether="
|
|
statement on the command line, or change the definition of ELP_DMA in 3c505.h.
|
|
|
|
The driver will warn you if it has to fall back on the compiled in
|
|
default DMA channel.
|
|
|
|
If no base address is given at boot time, the driver will autoprobe
|
|
ports 0x300, 0x280 and 0x310 (in that order). If no IRQ is given, the driver
|
|
will try to probe for it.
|
|
|
|
The driver can be used as a loadable module.
|
|
|
|
Theoretically, one instance of the driver can now run multiple cards,
|
|
in the standard way (when loading a module, say "modprobe 3c505
|
|
io=0x300,0x340 irq=10,11 dma=6,7" or whatever). I have not tested
|
|
this, though.
|
|
|
|
The driver may now support revision 2 hardware; the dependency on
|
|
being able to read the host control register has been removed. This
|
|
is also untested, since I don't have a suitable card.
|
|
|
|
Known problems:
|
|
I still see "DMA upload timed out" messages from time to time. These
|
|
seem to be fairly non-fatal though.
|
|
The card is old and slow.
|
|
|
|
To do:
|
|
Improve probe/setup code
|
|
Test multicast and promiscuous operation
