separate from a network device (a link-layer concept).

those functions we are likely to need.

Still need to come up with a way of getting the linker to create
static lists using this linking mechanism.

Add 'raw' net_addr facility (needed for ARP).

kernel.

Removed obsolete struct arprequest from if_arp.h and put it in nic.c so
that nic.c will still compile.  ARP will very shortly be handled by
net/arp.c instead.

Added set_ipaddr().

the first standalong uIP-based protocol module.

the definition of it uses offsetof(), and the two concepts are related.

yet, in order to allow prototester.c to compile.  It might be worth
changing all the uses of "%@" in printf to use "%s" and inet_ntoa
instead, in order to improve the portability of our code.

tcp.h.

linker_assert() defined as gPXE-specific.

Make await_tftp() static and create tftp_get() for fetching the next TFTP
packet instead.

shared between TFTP, TFTM and MTFTP protocols.

s_PXENV_TFTP_READ_FILE.

Added reason for min value of 512 on s_PXENV_TFTP_OPEN::PacketSize.

the Etherboot implementation (i.e. don't do what Intel did).

PXE code now compiles without errors (though it won't actually work).
