Don't rely on retry.c's periodically calling currticks() in order to

allow the UNDI NIC interrupt to happen.

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.

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.

Don't call PXENV_STOP_UNDI in the kpxeprefix. This slighy breaks the

clean separation between loading and starting, but does mean that more

Always send EOI. We can't feasibly share interrupts (since we have no
...
clue what the "previous" interrupt handler will do, which could range
from "just an iret" to "disable the interrupt"), and that means that
we have to take responsibility for ACKing all interrupts. Joy.

Add "name" field to struct device to allow human-readable hardware device
...
names.
Add "dev" pointer in struct net_device to tie network interfaces back to a
hardware device.
Force natural alignment of data types in __table() macros. This seems to
prevent gcc from taking the unilateral decision to occasionally increase
their alignment (which screws up the table packing).

Add RX quotas to the net device poll() method. This avoids the problem
...
of alloc_pkb() exhaustion when e.g. an iSCSI-booted DOS session is left
idle for a long time at the C:\ prompt and builds up a huge packet
backlog.

Use "struct undi_device" instead of "struct pxe_device", and use the
...
function prefix "undinet_" and the variable name "undinic" in undinet.c,
so that we can reserve the variable name "undi" for a struct undi_device.
The idea is that we preserve the Etherboot 5.4 convention that the "UNDI"
code refers to our using an underlying UNDI stack, while the "PXE" code
refers to our providing a PXE API.
