IB/ipath: Add support for 7220 receive queue changes
Newer HCAs have a HW option to write a sequence number to each receive
queue entry and avoid a separate DMA of the tail register to memory.
This patch adds support for these changes.

IB/ipath: Make send buffers available for kernel if not allocated to user
A fixed partitioning of send buffers is determined at driver load time
for user processes and kernel use. Since send buffers are a scarce
resource, it makes sense to allow the kernel to use the buffers if they
are not in use by a user process.
Also, eliminate code duplication for ipath_force_pio_avail_update().

IB/ipath: Head of Line blocking vs forward progress of user apps
There's a conflict between our need to quiesce PSM-based applications
to avoid HoL blocking when the IB link goes down and the apps' desire
to remain running so that their quiescence timout mechanism can keep
running.
The compromise is to STOP the processes for a fixed period of time and
then alternate between CONT and STOP until the link is again active.
If there are poor interactions with subnet manager configuration at a
given site, the interval can be adjusted via a module paramter.

IB/ipath: Fix IB compliance problems with link state vs physical state
Subnet manager SetPortinfo messages distingush between changing the link
state (DOWN, ARM, ACTIVE) and the link physical state (POLL, SLEEP,
DISABLED). These are somewhat independent commands and affect when link
width and speed changes take effect. Without this patch, a link DOWN
physical state NOP command was causing the link width and speed settings
to take effect which should only happen when the link physical state is
goes down (either by a SMP or some link physical error like link errors
exceeding the threshold).

IB/ipath: Change packet problems vs chip errors handling and reporting
Some types of packet errors are moderately common with longer IB
cables and large clusters, and are not reported with prints by other
IB HCA drivers. This suppresses those messages unless the new
__IPATH_ERRPKTDBG bit is set in ipath_debug. Reporting of temporarily
disabled frequent error interrupts was also made clearer
We also distinguish between chip errors, and bad packets sent or
received in the wording of the messages.
