Determine the network-layer packet type and fill it in for UNDI
clients. This is required by some NBPs such as emBoot's winBoot/i.
This change requires refactoring the link-layer portions of the
gPXE netdevice API, so that it becomes possible to strip the
link-layer header without passing the packet up the network stack.
[undi] Work around broken UNDI polling behaviour in winBoot/i2008-08-20T01:02:51+00:00Michael Brown2008-08-20T01:02:51+00:00urn:sha1:f6f6f626f7f63269c92932e7701392d619c44312
Some dumb NBPs (e.g. emBoot's winBoot/i) never call PXENV_UNDI_ISR
with FuncFlag=PXENV_UNDI_ISR_START; they just sit in a tight polling
loop merrily violating the PXE spec with repeated calls to
PXENV_UNDI_ISR_IN_PROCESS. Force a extra calls to netdev_poll() to
cope with these out-of-spec clients.
[i386] Change semantics of __from_data16 and __from_text162008-07-01T01:52:13+00:00Michael Brown2008-07-01T01:52:13+00:00urn:sha1:4fbbf651d7cb91983801904f5ed2b07d15566c1d
__from_data16 and __from_text16 now take a pointer to a
.data16/.text16 variable, and return the real-mode offset within the
appropriate segment. This matches the use case for every occurrence
of these macros, and prevents potential future bugs such as that fixed
in commit d51d80f. (The bug arose essentially because "&pointer" is
still syntactically valid.)

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.
