iw_cxgbe: Remove unused return value from destroy_cq
Part of the original Linux commit was already applied during a prior
OFED update in commit b633e08c705fe43180567eae26923d6f6f98c8d9, but
this portion of the changes to the Linux iw_cxgb4 driver were not
included.
Obtained from: Linux commit a52c8e2469c30cf7ac453d624aed9c168b23d1af
iw_cxgbe: Fix qpid leak
Add await in destroy_qp() so that all references to qp are dereferenced
and qp is freed in destroy_qp() itself. This ensures freeing of all QPs
before invocation of dealloc_ucontext(), which prevents loss of in use
qpids stored in the ucontext.
Obtained from: Linux commit f70baa7ee3d1b5a9e66ac7549e31641a656f23c1

iw_cxgbe: Miscellaneous changes from the iw_cxgb4 driver
These include changes to use newer APIs, cosmetic changes to reduce
diffs between the two drivers, and other minor fixes.

iw_cxgbe/libcxgb4: Pass ftid_base to libcxgb4 through status page
While here, fix incorrect frees in error paths in c4iw_alloc_context().

cxgbe: Enable RDMA WRITE_CMPL work requests if the firmware supports them
This work request permits combining RDMA WRITE and SEND_INV commands
into a single work request.

libcxgb4: remove update_qp_state()
Remove it because it is not needed. If we're flushing the qp, it is
because we've had a fatal error, so just set the user qp state to ERR
and continue on.

iw_cxgbe/libcxgb4: Support for RDMA WRITE_COMPL work requests
To optimize NVME-oF READ IOPs, use a specialized work request that
combines a RDMA WRITE and SEND_INV chain into a single request.

iw_cxgbe: use __raw_write*() to allow write-combining
pio_copy() is suppose to be used for write-combining work requests.
However, for some architectures like powerpc and arm64, write[ql]()
include an explicit memory barrier which will flush the WC buffer and
render this path useless. To prevent that use the relaxed variant.

iw_cxgbe: Various fixes around waiting for replies to work requests
Allocate wait objects dynamically and add a refcount instead of
allocating them on the current thread's stack. This permits
c4iw_wait_for_reply() to safely fail with an error and mark the device
as dead if a reply is not received after C4IW_WR_TO seconds. Once a
device is marked dead, future requests fail immediately.

libcxgb4: Support send/recv drain work requests
This change allows libcxgb4 to post send/recv drain work requests
after a QP is flushed and schedules a CQE on the software CQ for the
application to note the drain's completion.

iw_cxgbe: Fixes around work queue flushing and draining
- Only insert drain CQEs if a work queue is flushed
- Preserve the request opcode of the original request when flushing a
request. Use bit 10 of the CQE header word to indicate the CQE is a
special drain completion, and save the original WR opcode in the cqe
header opcode field.
- If a work request chain was posted and needed to be flushed, only
the first request in the chain was completed with FLUSHED status.
The rest were never completed.
- When a CQ is shared by multiple QPs, c4iw_flush_hw_cq() needs to
acquire the corresponding QP lock before moving the CQEs into its
corresponding SW queue and accessing the SQ contents for completing
a WR.
- Once a user QP has been flushed, it cannot be flushed again.

iw_cxgbe/libcxgb4: Support 64B CQEs
The larger CQE exports the RSS header to userspace. Note that this
changes the ABI between the driver and library, so the ABI version is
bumped. A new user->kernel create_cq request message is defined to
disallow a CQE size mismatch between iw_cxgbe and libcxgb4.
