[PATCH AUTOSEL 4.14 38/60] RDMA/i40iw: Set queue pair state when being queried

[PATCH AUTOSEL 4.14 38/60] RDMA/i40iw: Set queue pair state when being queried

[Sasha Levin]

From: "Liu, Changcheng" <changcheng.liu@intel.com>

[ Upstream commit 2e67e775845373905d2c2aecb9062c2c4352a535 ]

The API for ib_query_qp requires the driver to set qp_state and
cur_qp_state on return, add the missing sets.

[PATCH AUTOSEL 4.14 46/60] RDMA/rxe: Fill in wc byte_len with IB_WC_RECV_RDMA_WITH_IMM

[Sasha Levin]

From: Konstantin Taranov <konstantin.taranov@inf.ethz.ch>

[ Upstream commit bdce1290493caa3f8119f24b5dacc3fb7ca27389 ]

Calculate the correct byte_len on the receiving side when a work
completion is generated with IB_WC_RECV_RDMA_WITH_IMM opcode.

According to the IBA byte_len must indicate the number of written bytes,
whereas it was always equal to zero for the IB_WC_RECV_RDMA_WITH_IMM
opcode, even though data was transferred.
