The Intel 10 Gigabit NICs use the same simplified (aka "legacy")
descriptor format and the same layout for descriptor register blocks
as the Intel 1 Gigabit NICs. The offsets of the descriptor register
blocks are not the same.
Simplify reuse of the existing code by removing all hardcoded offsets
for registers within descriptor register blocks, and ensuring that all
offsets are calculated using the descriptor register block base
address provided via intel_init_ring().

The Intel NIC emulation in some versions of VMware seems to suffer
from a flaw whereby the Interrupt Cause Register (ICR) fails to assert
the usual "packet received" bit (ICR.RXT0) if a receive overflow
(ICR.RXO) has also occurred.
Work around this flaw by polling for completed descriptors whenever
either ICR.RXT0 or ICR.RXO is asserted.

Almost all clients of the raw-packet interfaces (UNDI and SNP) can
handle only Ethernet link layers. Expose an Ethernet-compatible link
layer to local clients, while remaining compatible with IPoIB on the
wire. This requires manipulation of ARP (but not DHCP) packets within
the IPoIB driver.
This is ugly, but it's the only viable way to allow IPoIB devices to
be driven via the raw-packet interfaces.

Some RTL8169 cards seem to drive the EEPROM CS line high (i.e. active)

that the CS line is never deasserted. The symptom of this is that the
first read from the EEPROM will work, while all subsequent reads will

Some RTL8169 cards (observed with an RTL8169SC) crash and burn if DAC
is enabled, even if only 32-bit addresses are used. Observed
behaviour includes system lockups and repeated transmission of garbage
data onto the wire.
This seems to be a known problem. The Linux r8169 driver disables DAC
by default and provides a "use_dac" module parameter.
There appears to be no known test for determining whether or not DAC
will work. As a workaround, enable DAC only if we are built as as
64-bit binary. This at least eliminates the problem in the common
case of a 32-bit build, which will never use 64-bit addresses anyway.

On 82576 (and probably others), the datasheet states that "the tail
register of the queue (RDT[n]) should not be bumped until the queue is

"enabled": the initialisation blurb says that we should "poll the
RXDCTL register until the ENABLE bit is set", while the description
for the RXDCTL register says that the ENABLE bit is set by default
(for queue zero). Empirical evidence suggests that the ENABLE bit
reads as set immediately after writing to RCTL.EN, and so polling is
not necessary.

The RS bit is used to instruct the NIC to update the TX descriptor
status byte. The RPS bit is used to instruct the NIC to defer this
update until after the packet has been transmitted on the wire (rather
than merely read into the transmit FIFO).
The driver currently sets RPS but not RS. Some e1000 models seem to
interpret this as implying that the status byte should be updated;
some don't. On the ones that don't, we never see any TX completions
and so rapidly run out of TX buffers.
Fix by setting the RS bit in the TX descriptor. (We don't care about
when the packet reaches the wire, so don't bother setting the RPS
bit.)

Also, the implementation is buggy: is_local_ether_addr() is used to

This patch adds a native iPXE virtio-net driver and removes the legacy
Etherboot virtio-net driver. The main reasons for doing this are:
1. Multiple virtio-net NICs are now supported by iPXE. The legacy
driver kept global state and caused issues in virtual machines with
more than one virtio-net device.
2. Faster downloads. The native iPXE driver downloads 100 MB over
HTTP in 12s, the legacy Etherboot driver in 37s. This simple
benchmark uses KVM with tap networking and the Python
SimpleHTTPServer both running on the same host.
Changes to core virtio code reduce vring descriptors to 256 (QEMU uses
128 for virtio-blk and 256 for virtio-net) and change the opaque token
from u16 to void*. Lowering the descriptor count reduces memory
consumption. The void* opaque token change makes driver code simpler.

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.
