The link state is currently set at probe time, and updated only when
the device is polled. This results in the user seeing a misleading
stale "Link: down" message, if autonegotiation did not complete within
the short timespan of the probe routine.
Fix by updating the link state when the device is opened, so that the
message that ends up being displayed to the user reflects the real
link state at device open time.

[netdevice] Allow network device to update link state before checking
If the network interface has only just been opened (e.g. by the "dhcp"
command) then we should allow at least one opportunity for the card to
update the link state before testing it, to avoid false positives.

There is no explicit SNP API call to determine link state; the SNP
interface user may check the MediaPresent field within the mode data
at any time.
Update the MediaPresent field whenever the link state changes.

[crypto] Allow trusted root certificate to be changed without a rebuild
Changing the trusted root certificate currently requires a rebuild of
the iPXE binary, which may be inconvenient or impractical.
Allow the list of trusted root certificate fingerprints to be
overridden using the "trust" setting, but only at the point of iPXE
initialisation. This prevents untrusted sources of settings
(e.g. DHCP) from subverting the chain of trust, while allowing
trustworthy sources to change the trusted root certificate without
requiring a rebuild.
The basic idea is that if you are able to manipulate a trustworthy
source of settings (e.g. VMware GuestInfo or non-volatile stored
options), then you would be able to replace the iPXE binary anyway,
and so no security is lost by allowing such sources to override the
list of trusted root certificates.

Solaris assumes that there is enough space above the Multiboot modules
to use as a decompression and scratch area. This assumption is
invalid when using iPXE, which places the Multiboot modules near the
top of (32-bit) memory.
Fix by copying the modules to an area of memory immediately following
the loaded kernel.

iPXE provides no support for manually configuring the link speed.
Provide a generic routine which should be able to reset any MII/GMII
PHY and enable autonegotiation.

[util] Add utility to generate list of supported network cards
niclist.pl recursively scans specified source folders and builds a
list of supported NICs by looking for ISA_ROM and PCI_ROM lines and
outputs the list in text, CSV, JSON, HTML or DokuWiki format. Sorting
and column selection is possible.
The pci-utils pci.ids file is fetched from SourceForge once a day to
also output the "official" vendor/device names associated with the PCI
device.

iPXE's support for COMBOOT images is now quite outdated; it has not
kept up to date with changes in the COMBOOT API. The primary use for
COMBOOT seems to be for menuing support. Now that we have native iPXE
script-based menus, COMBOOT support can be gracefully retired (with
immense thanks to Daniel Verkamp for having successfully implemented
such an ambitious feature many years ago).
