Allow user space applications to accelerate send and receive
traffic which is typically handled by IPoIB ULP by creating
a UD QP with a given source QPN of the IPoIB UD QP.

UD QP with a given source QPN should basically be similar to
RAW QP from point of view of its created resources.

However,
- Its TIS should point to the source QPN.
- Modify can be done only on its state as the transport attributes
  are managed by its source QP.

During attach or detach multicast, when the QP is associated with a

RQs that were configured for "delay drop" will prevent packet drops
when their WQEs are depleted.
Marking an RQ to be drop-less is done by setting delay_drop_en in RQ
context using CREATE_RQ command.

Since this feature is globally activated/deactivated by using the
SET_DELAY_DROP command on all the marked RQs, we activated/deactivated
it according to the number of RQs with 'delay_drop' enabled.

When timeout is expired, then the feature is deactivated. Therefore
the driver handles the delay drop timeout event and reactivate it.

Currently, unicast/multicast loopback raw ethernet
(non-RDMA) packets are sent back to the vport.
A unicast loopback packet is the packet with destination
MAC address the same as the source MAC address.
For multicast, the destination MAC address is in the
vport's multicast filter list.

Moreover, the local loopback is not needed if
there is one or none user space context.

After this patch, the raw ethernet unicast and multicast
local loopback are disabled by default. When there is more
than one user space context, the local loopback is enabled.

Note that when local loopback is disabled, raw ethernet
packets are not looped back to the vport and are forwarded
to the next routing level (eswitch, or multihost switch,
or out to the wire depending on the configuration).

Prepping for scripting the MAINTAINERS file cleanup (and possible split)
showed a couple of cases where the headers for a couple of entries were
bogus.

There's a few different kinds of bogosities:

 - the X-GENE SOC EDAC case was confused and split over two lines

 - there were four entries for "GREYBUS PROTOCOLS DRIVERS" that were all
   different things.

 - the NOKIA N900 CAMERA SUPPORT" was duplicated

all of which were more obvious when you started doing associative arrays
in perl to track these things by the header (so that we can alphabetize
this thing properly, and so that we might split it up by the data too).

When setting up the Xenstore watch for the memory target size the new

by onlining new memory in this case, as the current memory size will
be smaller in almost all cases due to e.g. BIOS reserved pages.

Onlining new memory will lead to more problems e.g. undesired conflicts
with NVMe devices meant to be operated as block devices.

Instead remember the difference between target size and current size
when the watch fires for the first time and apply it to any further
size changes, too.

Pull block fixes from Jens Axboe:
 "A small set of fixes for -rc2 - two fixes for BFQ, documentation and
  code, and a removal of an unused variable in nbd. Outside of that, a
  small collection of fixes from the usual crew on the nvme side"

Pull more rdma fixes from Doug Ledford:
 "As per my previous pull request, there were two drivers that each had
  a rather large number of legitimate fixes still to be sent.

  As it turned out, I also missed a reasonably large set of fixes from
  one person across the stack that are all important fixes. All in all,
  the bnxt_re, i40iw, and Dan Carpenter are 3/4 to 2/3rds of this pull
  request.

  There were some other random fixes that I didn't send in the last pull
  request that I added to this one. This catches the rdma stack up to
  the fixes from up to about the beginning of this week. Any more fixes
  I'll wait and batch up later in the -rc cycle. This will give us a
  good base to start with for basing a for-next branch on -rc2.

  Summary:

   - i40iw fixes

   - bnxt_re fixes

   - Dan Carpenter bugfixes across stack

   - ten more random fixes, no more than two from any one person"
