Enable the "show" command to display the full, canonicalised name of
the fetched setting. For example:
iPXE> show mac
net0/mac:hex = 52:54:00:12:34:56
iPXE> dhcp && show ip
DHCP (net0 52:54:00:12:34:56)... ok
net0.dhcp/ip:ipv4 = 10.0.0.168
iPXE> show net0/6
net0.dhcp/dns:ipv4 = 10.0.0.6

Re-open the EFI_PCI_IO_PROTOCOL specifying an Attributes value of
EFI_OPEN_PROTOCOL_BY_CHILD_CONTROLLER. This causes the SNP devices to
be marked as children of the EFI PCI device (as shown in the "devtree"
command).
On at least one IBM blade system, this is required in order to have
the relevant drivers automatically attach to the SNP controller at
device creation time.

Some prefixes (e.g. .lkrn) allow a command line to be passed in to
iPXE. At present, this command line is ignored.
If a command line is provided, treat it as an embedded script (without
an explicit "#!ipxe" magic marker). This allows for patterns of
invocation such as
title iPXE
kernel /boot/ipxe.lkrn dhcp && \
sanboot iscsi:10.0.4.1::::iqn.2010-04.org.ipxe.dolphin:storage
Here GRUB is instructed to load ipxe.lkrn with an embedded script
equivalent to
#!ipxe
dhcp
sanboot iscsi:10.0.4.1::::iqn.2010-04.org.ipxe.dolphin:storage
This can be used to effectively vary the embedded script without
having to rebuild ipxe.lkrn.

Refactor the {load,exec} image operations as {probe,exec}. This makes
the probe mechanism cleaner, eliminates some forward declarations,
avoids holding magic state in image->priv, eliminates the possibility
of screwing up between the "load" and "exec" stages, and makes the
documentation simpler since the concept of "loading" (as distinct from
"executing") no longer needs to be explained.

The online documentation (e.g. http://ipxe.org/cmd/ifopen), though not
yet complete, is far more comprehensive than could be provided within
the iPXE binary. Save around 200 bytes (compressed) by removing the
command descriptions from the interactive help, and instead referring
users directly to the web page describing the relevant command.

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
or a dhcpd.conf option such as
option iscsi-initiator-iqn "iqn.2000-09.org.etherboot:UNKNOWN"

Some iSCSI targets (observed with a Synology DS207+ NAS) send
unsolicited NOP-Ins to the initiator. RFC 3720 is remarkably unclear
and possibly self-contradictory on how NOPs are supposed to work, but
it seems as though we can legitimately just ignore any unsolicited
NOP-In PDU.

Commit d7736fb ("[efi] Allow EFI to control PCI bus enumeration")
introduced a bug in which the EFI driver name became an
(uninitialised) pointer rather than an array.
Signed-off-by: Michael Brown <mcb30@ipxe.org>
EFI performs its own PCI bus enumeration. Respect this, and start
controlling devices only when instructed to do so by EFI.
As a side benefit, we should now correctly create multiple SNP
instances for multi-port devices.
This should also fix the problem of failing to enumerate devices
because the PCI bridges have not yet been enabled at the time the iPXE
driver is loaded.
Signed-off-by: Michael Brown <mcb30@ipxe.org>

For performing installations direct to a SAN target, it can be very
useful to hook a SAN disk and then proceed to perform a filename boot.
For example, the user may wish to hook the (empty) SAN installation
disk and then boot into the OS installer via TFTP. This provides an
alternative mechanism to using "keep-san" and relying on the BIOS to
fall through to boot from the installation media, which is unreliable
on many BIOSes.
When a root-path is specified in addition to a boot filename, attempt
to hook the root-path as a SAN disk before booting from the specified
filename. Since the root-path may be used for non-SAN purposes
(e.g. an NFS root mount point), ignore the root-path if it contains a
URI scheme that we do not support.
