This reverts commit 15c1200 ("[hermon] Work around missing mport
support in current BOFM implementations").
Signed-off-by: Michael Brown <mcb30@ipxe.org>
Current BOFM versions are unable to create entries with mport>1, which
means that only the port 1 MAC address can be explicitly specified.
Work around this by using the provided MAC address as a base address
for all subsequent ports. For example, if BOFM assigns the address
00:1A:64:76:00:09 for port 1
then we will assign the addresses
00:1A:64:76:00:09 for port 1
00:1A:64:76:00:0a for port 2
Future BOFM versions that may correctly support mport will work with
this scheme without modification provided that the BOFM entries are
created in increasing order of mport. Since BOFM tools tend to
generate entries in increasing order (of slot, port, etc), this is not
an unreasonable compromise.

The forcedeth driver currently implements unicast MAC address
filtering in software. This is almost invariably the wrong thing to
do (since the network stack must already be able to cope with unwanted
packets) and it breaks FCoE (which requires the card to operate in
promiscuous mode).
Also, the implementation is buggy: is_local_ether_addr() is used to
check for a locally-assigned Ethernet address (not to check for a
unicast address), and the current link-layer address is in
netdev->ll_addr, not netdev->hw_addr.
Fix by removing this code.

The default initiator IQN is "iqn.2000-09.org.etherboot:UNKNOWN".
This is problematic for two reasons:
a) the etherboot.org domain (and hence the associated IQN namespace)
is not under the control of the iPXE project, and
b) some targets (correctly) refuse to allow concurrent connections
from different initiators using the same initiator IQN.
Solve both problems by changing the default initiator IQN to be
iqn.2010-04.org.ipxe:<hostname> if a hostname is set, or
iqn.2010-04.org.ipxe:<uuid> if no hostname is set.
Explicit initiator IQNs set via DHCP option 203 are not affected by
this change.
Unfortunately, this change is likely to break some existing
configurations, where ACL rules have been put in place referring to
the old default initiator IQN. Users may need to update ACLs, or
force the use of the old IQN using an iPXE script line such as
set initiator-iqn iqn.2000-09.org.etherboot:UNKNOWN

The block device interface used in gPXE predates the invention of even
the old gPXE data-transfer interface, let alone the current iPXE
generic asynchronous interface mechanism. Bring this old code up to
date, with the following benefits:
o Block device commands can be cancelled by the requestor. The INT 13
layer uses this to provide a global timeout on all INT 13 calls,
with the result that an unexpected passive failure mode (such as
an iSCSI target ACKing the request but never sending a response)
will lead to a timeout that gets reported back to the INT 13 user,
rather than simply freezing the system.
o INT 13,00 (reset drive) is now able to reset the underlying block
device. INT 13 users, such as DOS, that use INT 13,00 as a method
for error recovery now have a chance of recovering.
o All block device commands are tagged, with a numerical tag that
will show up in debugging output and in packet captures; this will
allow easier interpretation of bug reports that include both
sources of information.
o The extremely ugly hacks used to generate the boot firmware tables
have been eradicated and replaced with a generic acpi_describe()
method (exploiting the ability of iPXE interfaces to pass through
methods to an underlying interface). The ACPI tables are now
built in a shared data block within .bss16, rather than each
requiring dedicated space in .data16.
o The architecture-independent concept of a SAN device has been
exposed to the iPXE core through the sanboot API, which provides
calls to hook, unhook, boot, and describe SAN devices. This
allows for much more flexible usage patterns (such as hooking an
empty SAN device and then running an OS installer via TFTP).

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.

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.

from the eepro100 driver and verified that the driver continued to
function. Christopher verified Thomas' patch on his integrated
eepro100 NIC.

The interrupt control mechanism on Phantom cards has changed
substantially since the driver was initially written. This updates
the code to match the mechanism used in production firmware.
This is sufficient to allow DOS wget to function successfully using
the 3Com UNDI/NDIS, Intel UNDI/NDIS, and UNDIPD.COM UNDI/PD stacks.

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.
