In a bidirectional forwarding test, we find that the best performance
is achieved by sending the TX completion interrupts from one NIC to a
CPU which shares an L2 cache with RX completion interrupts from the
other NIC. To facilitate this, add an option (through a module
parameter) to create separate channels for RX and TX completion with
separate IRQs when MSI-X is available.

The SFC4000 has strap pins indicating the presence of SPI flash and/or
EEPROM. These pins are also used for GPIO, and in some cases they may
be read wrongly at reset. However, on production boards it must boot
from one or the other device, so we can assume the boot device is
present and read the board config from there.

Make falcon_spi_wait() ignore the write timer - it is only relevant to
write commands, it only works for the device that contains VPD, and it
might not be initialised properly at all.
Rename falcon_spi_fast_wait() to falcon_spi_wait_write(), reflecting
its use, and make it wait up to 10 ms (not 1 ms) since buffered writes
to EEPROM may take this long to complete.
Make both wait functions sleep instead of busy-waiting.
Replace wait for command completion at top of falcon_spi_cmd() with a
single poll; no command should be running when the function starts.
Correct some comments.

Implements the KS8695 ethernet device (ks8695net).
This driver is only of use on the KS8695 which is an ARM9 based SoC. The
documentation on this SoC is sparse and poor, with barely a register
description and a rough outline of how the ethernet works, this driver was
therefore written with strong reference to the Micrel supplied Linux 2.6.9
port, and to Andrew Victor's ks8695eth driver.
