The current method for ICM allocation exactly matches the addresses
chosen by the old Etherboot driver, but does not match the
specification. Some ICM tables (notably the queue pair context table)
therefore end up incorrectly aligned.
Fix by performing allocations as per the specification.

Improve the utility of debugging messages by including the relevant
port number, queue number (QPN, CQN, EQN), work queue entry (WQE)
number, and physical addresses wherever applicable.
Add arbel_dump_cqctx() for dumping a completion queue context and
arbel_dump_qpctx() for dumping a queue pair context.

This is a backport of commit 0b1222f ("[hermon] Randomise the
high-order bits of queue pair numbers") to the Arbel driver.

This is a backport of commit cd5a213 ("[hermon] Allow software GMA to
receive packets destined for QP1") to the Arbel driver.
This patch includes a correction to a bug in the autogenerated
hardware description header file.

Only port state change events are currently mapped to our event queue,
since those are the only events we are prepared to handle. This
ignores a potentially useful source of diagnostic information in the
case of unexpected failures.
Fix by mapping all events to the event queue; a build with debugging
enabled will therefore at least dump the raw content of the unexpected
events.

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resources has been revoked by the registrant of the domain.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.

Arbel and Hermon cards both have multiple ports. Add the
infrastructure required to register each port as a separate IB
device. Don't yet register more than one port, since registration
will currently fail unless a valid link is detected.
Use ib_*_{set,get}_{drv,owner}data wrappers to access driver- and
owner-private data on Infiniband structures.
