* RDMA/irdma: Fix RQ completion opcodeMustafa Ismail2022-11-171-0/+1
| | | | | | | | | | | | | | | | | | | | 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: Fix inline for multiple SGE'sMustafa Ismail2022-11-171-17/+2
| | | | | | | | | | | | Currently, inline send and inline write assume a single SGE and only copy data from the first one. Add support for multiple SGE's.

* RDMA/irdma: Align AE id codes to correct flush code and eventSindhu-Devale2022-09-201-0/+1
| | | | | | | | | | | | | | | A number of asynchronous event (AE) ids were not aligned to the correct flush_code and event_type. Fix these up so that the correct IBV error and event codes are returned to application. Also, add handling for new AE ids like IRDMA_AE_INVALID_REQUEST to return the correct WC error code.

* RDMA/irdma: optimize rx path by removing unnecessary copyZhu Yanjun2021-11-011-15/+8
| | | | | | | | | | | | | | In the function irdma_post_recv, the function irdma_copy_sg_list is not needed since the struct irdma_sge and ib_sge have the similar member variables. The struct irdma_sge can be replaced with the struct ib_sge totally. This can increase the rx performance of irdma.
