Require drivers to report the total number of Infiniband ports. This
is necessary to report the correct number of ports on devices with
dynamic port types.
For example, dual-port Mellanox cards configured for (eth, ib) would
be rejected by the subnet manager, because they report using "port 2,
out of 1".

Any underlying errors arising during ib_create_cq() or ib_create_qp()
are lost since the functions simply return NULL on error. This makes
debugging harder, since a debug-enabled build is required to discover
the root cause of the error.
Fix by returning a status code from these functions, thereby allowing
any underlying errors to be propagated.

iPXE currently uses the first port's port GUID as the node GUID,
rather than using the (possibly distinct) real node GUID. This can
confuse opensm during the handover to a loaded OS: it thinks the port
already belongs to a different node and so discards our port
information with a warning message about duplicate ports. Everything
is picked up correctly on the second subnet sweep, after opensm has
established that the "old" node no longer exists, but this can delay
link-up unnecessarily by several seconds.
Fix by using the real node GUID.

Replace the explicit calls from the Infiniband core to the IPoIB layer
with the general concept of an Infiniband upper-layer driver
(analogous to a PCI driver) which can create arbitrary devices on top
of Infiniband 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resources has been revoked by the registrant of the domain.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.
