addresses. Support this by operating in promiscuous mode.

[rtl8139] Check for oversized packets when transmitting
An attempt to transmit a packet of 8192 bytes or larger will collide
with the status bits in the TX descriptor. This gives the appearance
of the network card's transmit data path having just suddenly stopped
responding; iPXE is waiting for the card to report a TX completion
but, because of the status bit collision, the card thinks that the
descriptor has not yet been written.
Fix by explicitly checking for oversized packets in rtl_transmit().
Discovered during Fibre Channel over Ethernet testing, and debugged by
using gdb to examine the state of the emulated rtl8139 card in qemu.

[infiniband] Add the concept of an Infiniband upper-layer driver

The rtl8139 driver includes the Ethernet CRC within the received
packet. All current protocols ignore trailing garbage, but FCoE
requires the frame length to be correct (since the FCoE footer
position is calculated from the end of the packet), so fix the driver
to strip out the CRC.

[forcedeth] Replace driver with native iPXE driver
This patch adds a native iPXE forcedeth driver and removes the legacy
Etherboot forcedeth driver. It supports 40 different chips, compared
to the original 14.
It has been tested on a NIC with an CK804 Ethernet Controller, and the
results of downloading 5 100mb images in a row have been:
12/11/11/11/11 seconds; booting DSL using pxelinux also succeeded. The
driver has also been tested by chaining undionly.kpxe and it worked.

[virtio] Replace virtio-net with native iPXE driver
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.

Add NonVolatile Option (nvo) and NonVolatile Storage (nvs) support to
the myri10ge driver using the EEPROM read/write mechanism provided by
the NIC's Vendor Specific PCI capability.
The myri10ge NIC is capabile of storing 64KB or more of nonvolatile
options, but this patch advertises only 512 bytes of nvo storage
because iPXE malloc's a buffer matching the total size we advertise.
512 is plenty without wasting malloc'd memory. (The 2 other drivers
currently supporting nvo advertise 256 bytes or less.)
