[pci] Allow pci_vpd_init() return status to be ignored
Most xxx_init() functions are void functions with no failure cases.
Allow pci_vpd_init() to be used in the same way. (Subsequent calls to
pci_vpd_read() etc. will fail if pci_vpd_init() fails.)

[nvo] Remove the non-volatile options fragment list
Since its implementation several years ago, no driver has used a
fragment list containing more than a single fragment. Simplify the
NVO core and the drivers that use it by removing the whole concept of
the fragment list, and using a simple (address,length) pair instead.

[settings] Apply settings block name in register_settings()
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).

[scsi] Wait for a successful TEST UNIT READY command
Some SCSI targets (observed with an EMC CLARiiON Fibre Channel target)
will not respond to commands correctly until a TEST UNIT READY has
been issued. In particular, a READ CAPACITY (10) command will return
with a success status, but no capacity data.
Fix by issuing a TEST UNIT READY command automatically, and delaying
further SCSI commands until the TEST UNIT READY has succeeded.

[hermon] Minimise the number of VPM mapping operations
Mapping a single page at a time causes a several-second delay at
device initialisation time. Reduce this by mapping multiple pages at
a time, using the largest block sizes possible given the alignment
constraints.

[arbel] Allocate only as much memory as is needed for firmware and ICM
Use individual page mappings rather than a single whole-region
mapping, to avoid the waste of memory that occurs due to the
constraint that each mapped block must be aligned on its own size.

[arbel] Synchronise changes with the Hermon driver

o Add arbel_rate() to calculate transmission rates
o Structure code to allow for addition of RC queue pairs

[arbel] Optimise ICM layout to reduce overall memory usage
Reduce the amount of ICM space required by choosing to order the
various allocations in approximately descending order of alignment
requirements.
This saves approximately 512kB of host memory.

[arbel] Perform ICM allocations according to the specification
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.

arbel_dump_qpctx() for dumping a queue pair context.

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.

[infiniband] Add node GUID as distinct from the first port GUID
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.

[infiniband] Always call ib_link_state_changed() in ib_smc_update()
ib_smc_update() potentially updates the Infiniband port state, and so
should almost always be followed by a call to ib_link_state_changed().
The one exception is the call made to ib_smc_update() before the
device is registered.
Fix by removing explicit calls to ib_link_state_changed() from drivers
using ib_smc_update(), including a call to ib_link_state_changed()
within ib_smc_update(), and creating a separate ib_smc_init() for use
prior to device registration.
