RDMA/irdma: Add wait for suspend on SQD Currently, there is no wait for the QP suspend to complete on a modify to SQD state. Add a wait, after the modify to SQD state, for the Suspend Complete AE. While we are at it, update the suspend timeout value in irdma_prep_tc_change to use IRDMA_EVENT_TIMEOUT_MS too.

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.

RDMA/irdma: Add table based lookup for CQ pointer during an event Add a CQ table based loookup to allow quick search for CQ pointer having CQ ID in case of CQ related asynchrononous event. The table is implemented in a similar fashion to QP table. Also add a reference counters for CQ. This is to prevent destroying CQ while an asynchronous event is being processed. The memory resource table size is sized higher with this update, and this table doesn't need to be physically contiguous, so use a vzalloc vs kzalloc to allocate the table.

RDMA/irdma: Fix RQ completion opcode The opcode written by HW, in the RQ CQE, is the RoCEv2/iWARP protocol opcode from the received packet and not the SW opcode as currently assumed. Fix this by returning the raw operation type and queue type in the CQE to irdma_process_cqe and add 2 helpers set_ib_wc_op_sq set_ib_wc_op_rq to map IRDMA HW op types to IB op types. Note that for iWARP, only Write with Immediate is supported so the opcode can only be IB_WC_RECV_RDMA_WITH_IMM when there is immediate data present.

RDMA/irdma: Add SW mechanism to generate completions on error HW flushes after QP in error state is not reliable. This can lead to application hang waiting on a completion for outstanding WRs. Implement a SW mechanism to generate completions for any outstanding WR's after the QP is modified to error. This is accomplished by starting a delayed worker after the QP is modified to error and the HW flush is performed. The worker will generate completions that will be returned to the application when it polls the CQ. This mechanism only applies to Kernel applications.
