The qib Infiniband device has long been decommissioned from distros and
unsupported by the company. We have kept it going in a compile only mode
for a while now and it's time to remove the driver. It has a number of
issues that are never going to be addressed and is a hindrance to
improving hfi1 and rdmavt.

Original patch for AH changes from Kamal Heib <kamalh@mellanox.com>, split
apart from original. This patch also removes the qib specific multicast
lid base and permissive lid defines since they are no longer needed.
Use common LID defines in qib driver.

1. The code accepts chunks of messages, and splits the chunk into
packets when converting packets into sdma queue entries. Adjacent
packets will use user buffer pages smartly to avoid pinning the
same page multiple times.
2. Instead of discarding all the work when SDMA queue is full, the
work is saved in a pending queue. Whenever there are enough SDMA
queue free entries, pending queue is directly put onto SDMA queue.
3. An interrupt handler is used to progress this pending queue.

External PSM repositories have advanced the minor number for a variety
of reasons. The driver needs to increase to avoid warnings.

We used to allow only full specification, or using all contexts within
an HCA before moving to the next HCA. We now allow an additional
method -- round-robining through HCAs -- and make that the default.
