Add the tap driver that can be used like:
$ ./ipxe.linux --net tap,if=tap0,mac=00:0c:29:c5:39:a1
The if setting is mandatory.

There exists an smbios userspace library so implementing this is
probably possible, but doesn't seem really important to have in
userspace. Hence provide a dummy implementation returning an error.

Add user access API for linux.
On linux userspace virtual == user == phys addresses. Physical
addresses also being the same is wrong, but there is no general way of
converting userspace addresses to physical as what appears to be
contiguous in userspace is physically fragmented. Currently only the
DMA memory is special-cased, but its conversion to bus addresses is
done in phys_to_bus. This is known to break virtio as it is passing
phys addresses to the virtual device.

Access to the gpxe.org and etherboot.org domains and associated
resources has been revoked by the registrant of the domain. Work
around this problem by renaming project from gPXE to iPXE, and
updating URLs to match.
Also update README, LOG and COPYRIGHTS to remove obsolete information.

For extremely tight space requirements and specific applications, it is
sometimes desirable to create gPXE images that cannot provide the PXE API
functionality to client programs. Add a configuration header option,
PXE_STACK, that can be removed to remove this stack. Also add PXE_MENU
to control the PXE boot menu, which most uses of gPXE do not need.

EFI provides a copy of the SMBIOS table accessible via the EFI system
table, which we should use instead of manually scanning through the
F000:0000 segment.
We have EFI APIs for CPU I/O, PCI I/O, timers, console I/O, user
access and user memory allocation.
EFI executables are created using the vanilla GNU toolchain, with the
EXE header handcrafted in assembly and relocations generated by a
custom efilink utility.
The userptr_t is now the fundamental type that gets used for conversions.
For example, virt_to_phys() is implemented in terms of virt_to_user() and
user_to_phys().
