Sindhu Devale 72d422c246 RDMA/irdma: Use HW specific minimum WQ size
HW GEN1 and GEN2 have different min WQ sizes but they are
currently set to the same value.

Use a gen specific attribute min_hw_wq_size and extend ABI to
pass it to user-space.

Sindhu Devale 3a84987204 RDMA/irdma: Allow accurate reporting on QP max send/recv WR
Currently the attribute cap.max_send_wr and cap.max_recv_wr
sent from user-space during create QP are the provider computed
SQ/RQ depth as opposed to raw values passed from application.
This inhibits computation of an accurate value for max_send_wr
and max_recv_wr for this QP in the kernel which matches the value
returned in user create QP. Also these capabilities needs to be
reported from the driver in query QP.

Add support by extending the ABI to allow the raw cap.max_send_wr and
cap.max_recv_wr to be passed from user-space, while keeping compatibility
for the older scheme.

The internal HW depth and shift needed for the WQs needs to be computed
now for both kernel and user-mode QPs. Add new helpers to assist with this:
irdma_uk_calc_depth_shift_sq, irdma_uk_calc_depth_shift_rq and
irdma_uk_calc_depth_shift_wq.

Consolidate all the user mode QP setup into a new function
irdma_setup_umode_qp which keeps it with its counterpart
irdma_setup_kmode_qp.

Lukas Bulwahn 514305ee0a RDMA/irdma: Make spdxcheck.py happy
Commit 48d6b3336a ("RDMA/irdma: Add ABI definitions") adds
./include/uapi/rdma/irdma-abi.h with an additional unneeded closing
bracket at the end of the SPDX-License-Identifier line.

Hence, ./scripts/spdxcheck.py complains:

  include/uapi/rdma/irdma-abi.h: 1:77 Syntax error: )

Remove that closing bracket to make spdxcheck.py happy.
