Some SoCs require a single scatterlist entry for smaller than page size,
i.e. 4KB. When dispatching commands with more than one scatterlist entry
under 4KB in size the following behavior is observed:
A command to read a block range is dispatched with two scatterlist entries
that are named AAA and BBB. After dispatching, the host builds two PRDT
entries and during transmission, device sends just one DATA IN because
device doesn't care about host DMA. The host then transfers the combined
amount of data from start address of the area named AAA. As a consequence,
the area that follows AAA in memory would be corrupted.
|<------------->|
+-------+------------ +-------+
+ AAA + (corrupted) ... + BBB +
+-------+------------ +-------+
To avoid this we need to enforce page size alignment for sg entries.

then must wait for those cancel completions prior to submitting a LUN RESET

proceed with channel enquiry to determine the maximum number of channels
the VIOS is capable of providing, and registering SubCRQs via channel setup
with the VIOS immediately following NPIV Login. This handshaking should not
be performed for subsequent NPIV Logins unless the CRQ connection has been
reset.
Implement these two new MADs and issue them following a successful NPIV
login where the VIOS has set the SUPPORT_CHANNELS capability bit in the
NPIV Login response.

adapters. This feature is a prerequisite for supporting multiple hardware
backed submission queues in the vfc adapter.
The Sub CRQ command element differs from the standard CRQ in that it is
32bytes long as opposed to 16bytes for the latter. Despite this extra
16bytes the ibmvfc protocol will use the original CRQ command element
mapped to the first 16bytes of the Sub CRQ element initially.
Add definitions for the Sub CRQ command element and queue.

other. Recent work as defined a generic queue structure with an event pool
specific to each queue. As such the event pool for each queue shouldn't be
allocated/freed independently, but instead performed as part of the queue
allocation/free routines.
Move the calls to ibmvfc_event_pool_{init|free} into

that the CRQ cannot be released in ibmvfc_remove until after the event pool
has been successfully purged since releasing the queue will also free the
