On advice of hpa: be more patient with the KBC and SCPA methods; retry
...
in a long loop before giving up on them. Record method which worked
and default to that method on next attempt.

Use fast in-situ test for gate A20 being set, to cut down on the
...
number of (potentially very slow) gateA20_set operations.
Die with a fatal error if we are unable to set gate A20; if this fails
then we are bound to experience memory corruption at a later stage,
and I'd prefer to pick it up early.

Improve error reporting for strange length combinations reported by
...
the UNDI stack.
Ignore obviously invalid length combinations (as returned by
e.g. VMWare's PXE stack).
Limit to one packet per poll to avoid memory exhaustion.

Set up %ds *before* testing a value in our data segment (d'oh!).
...
Always send EOI; do not chain to BIOS's default interrupt handler.
They are just too unpredictable; at least VMware's seems to kill the
machine if you go anywhere near it.
Disable interrupts after return from PXENV_UNDI_ISR, just in case some
dumb PXE stack enables them.

Use net_device_operations structure and netdev_nullify() to allow for
...
safe dropping of the netdev ref by the driver while other refs still
exist.
Add netdev_irq() method. Net device open()/close() methods should no
longer enable or disable IRQs.
Remove rx_quota; it wasn't used anywhere and added too much complexity
to implementing correct interrupt-masking behaviour in pxe_undi.c.
