Allow the link layer to directly report whether or not a packet is
multicast or broadcast at the time of calling pull(), rather than
relying on heuristics to determine this at a later stage.

Allow TX errors to be recorded against a network device even when the
packet didn't make it as far as netdev_tx().

Expose a function setting_applies() to allow a caller to determine
whether or not a particular setting is applicable to a particular
settings block.
Restrict DHCP-backed settings blocks to accepting only DHCP-based
settings.
Restrict network device settings blocks to accepting only DHCP-based
settings and network device-specific settings such as "mac".

Pass the settings block name as a parameter to register_settings(),
rather than defining it with settings_init() (and then possibly
changing it by directly manipulating settings->name).

Several use cases (e.g. the UNDI API and the EFI SNP API) require
access to the raw network device receive queue, and so currently use
manual calls to netdev_poll() on a specific network device in order to
prevent received packets from being processed by the network stack.
As an alternative, provide a flag that allows receive queue processing
to be frozen on a per-device basis. When receive queue processing is
frozen, packets will be enqueued as normal, but will not be
automatically dequeued and passed up the network stack.

FCoE requires the use of fabric-provided MAC addresses, which breaks
the assumption that the net device's MAC address is implicitly the
source address for net_tx() and the (unicast) destination address for
net_rx().

Add the concept of a network upper-layer driver, which can create
arbitrary devices on top of network devices.

Access to the gpxe.org and etherboot.org domains and associated
resources has been revoked by the registrant of the domain. Work
around this problem by renaming project from gPXE to iPXE, and
updating URLs to match.
Also update README, LOG and COPYRIGHTS to remove obsolete information.
