[hermon] Use correct alignment for doorbell records
Doorbell records are currently embedded within the completion queue
and receive work queue strucures, which are allocated using zalloc()
and so have an alignment guarantee of only sizeof(void*), i.e. four
bytes. This is sufficient for the receive work queue, but not for the
completion queue, which requires an alignment guarantee of eight
bytes.
Though not guaranteed, it so happens that zalloc() will always return
a pointer that is exactly four bytes above a sixteen-byte boundary.
The completion queue doorbell record is therefore always misaligned,
and the value passed to the hardware via SW2HW_CQ is actually always
pointing to the page_offset value within the MTT descriptor (which
directly precedes the inline doorbell record). Provided that the page
offset is greater than 0x100, this looks to the hardware like an
update_ci value of greater than 0x010000 (taking into account
endianness differences), and so the hardware will happily deliver more
than 0x010000 completions before stopping. Hence this problem is
rarely observable.
Fix by allocating the doorbell records separately and using the
correct alignment constraints.

Improve the utility of debugging messages by including the relevant

[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.

The rtl8139 driver includes the Ethernet CRC within the received

[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 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.)

[interface] Convert all data-xfer interfaces to generic interfaces
Remove data-xfer as an interface type, and replace data-xfer
interfaces with generic interfaces supporting the data-xfer methods.
Filter interfaces (as used by the TLS layer) are handled using the
generic pass-through interface capability. A side-effect of this is
that deliver_raw() no longer exists as a data-xfer method. (In
practice this doesn't lose any efficiency, since there are no
instances within the current codebase where xfer_deliver_raw() is used
to pass data to an interface supporting the deliver_raw() method.)
