This commit adds an igb (Intel GigaBit) driver based on Intel source
code available at:
http://sourceforge.net/projects/e1000/
which is upstream source for the Linux kernel e1000 drivers, and
should support some PCIe e1000 variants.

This commit replaces the current gPXE e1000 driver with one ported
from Intel source code available at
http://sourceforge.net/projects/e1000/
which is upstream source for the Linux kernel e1000 drivers, and
should support most if not all PCI e1000 variants.

This code is based on the linux skge driver. It supports Marvell Yukon
and SysKonnect Gigabit chipsets.
The code is based on code Michael Decker <mrd999@gmail.com> wrote for
Google Summer of Code 2008.
Support for dual-port cards is untested. The code, however, was left
in. In my opinion it's easier to fix the code if we need to, instead
of having to add support for it from scratch.

We add a syslinux floppy disk type using parts of the genliso script.
This floppy image cat be dd'ed to a physical floppy or used in
instances where a virtual floppy with an mountable DOS filesystem is
useful.
We also modify the genliso script to only generate .liso images
rather than creating images depending on how it is called.

At POST time some BIOSes return invalid e820 maps even though
they indicate that the data is valid. We add a check that the first
region returned by e820 is RAM type and declare the map to be invalid
if it is not.
This extends the sanity checks from 8b20e5d ("[pcbios] Sanity-check
the INT15,e820 and INT15,e801 memory maps").
When compiling for the Linux kernel, PCI_BASE_ADDRESS_0 == 0, and
PCI_BASE_ADDRESS_1 == 1. This is not so when compiling for gPXE. We
must use the symbolic names rather than integers to get the correct
values.

stappers and xl0 pointed out that gnu make sets some variables, so ?=
is ineffective in some cases where we use it.. Cross-compilation
requires that some variables can be overridden in the
src/$(ARCH)/Config file, so include that file _after_ utility program
variables are set.

Hello,
gPXE didn't work on 3COM 905C Tornado cards for me.
It did transmit the DHCP request, but it didn't see the DHCP offer.
Adding debug print statements allready solved the problem.
Attached is a patch that has a cleaner delay then print statements.
The core of it is
- for(i=0;i<40000;i++);
+ mdelay(1);
There was no research if the change is about a longer delay
or about code NOT being optimized away. It works for me :-)
Cheers

The e1000_irq() routine should (per mcb30) do enable on non-zero,
disable on zero. This is not consistent in all drivers, so I'll
wait to update it when doing a global sweep.
This needs to be done manually because if the irq() routine is
implemented then we want something like "nic->irqno = pci->irqno;",
else we do "nic->irqno = 0;" nic->ioaddr may also need to be set
carefully.
Also added local variables to end of many files, for emacs indentation
to match kernel style (tab does 8 space indent).
There may still be an issue with memory handling, since it seems to
die ungracefully when ARP packets come in after loading a kernel.
Something to debug.
This driver really needs to be rewritten.
It tries to build both ISA and PCI images,
and makes life diffifult for the build system
and rom-o-matic.net. The warning was just a reminder
that it needs to be cleaned up and re-factored
to split the PCI and ISA drivers.
This ancient ISA driver should probably be removed.
It is hard to get a card to test it with, and there
are comments to the effect that it cannot work with
relocation. I would be quite interested to get a
bug report by someone who actually has this card.
