Some resources are incorrectly organized and at odds with HW capabilities. Specifically, ILQ, IEQ, QPs, MSS, QOS and statistics belong in a VSI. Signed-off-by:

Currently we are changing the MSS regardless of whether there is a change or not in MTU. Fix to make the assignment of MSS dependent on an MTU change. Signed-off-by:

Add a QP reference when terminate timer is started to ensure the destroy QP doesn't race ahead to free the QP while it is being referenced in the terminate timer's handler. Signed-off-by:

On a device close, the control QP (CQP) is destroyed by calling cqp_destroy which destroys the CQP and frees its SD buffer memory. However, if the reset flag is true, cqp_destroy is never called and leads to a memory leak on SD buffer memory. Fix this by always calling cqp_destroy, on device close, regardless of reset. The exception to this when CQP create fails. In this case, the SD buffer memory is already freed on an error check and there is no need to call cqp_destroy. Signed-off-by:

When flush QP and there are no pending work requests, signal completion to unblock i40iw_drain_sq and i40iw_drain_rq which are waiting on completion for iwqp->sq_drained and iwqp->sq_drained respectively. Also, signal completion if flush QP fails to prevent the drain SQ or RQ from being blocked indefintely. Signed-off-by:

A QP can be double freed if i40iw_cm_disconn() is called while it is currently being freed by i40iw_rem_ref(). The fix in i40iw_cm_disconn() will first check if the QP is already freed before making another request for the QP to be freed. Signed-off-by:

hw_stats is a pointer to i40_iw_dev_stats struct in i40iw_get_hw_stats(). Use hw_stats and not &hw_stats in the memcpy to copy the i40iw device stats data into rdma_hw_stats counters.

The macros I40IW_STAG_KEY_FROM_STAG and I40IW_STAG_INDEX_FROM_STAG are apparently bad - they are using the logical "&&" operation which does not make sense here. It should have been a bitwise "&" instead. Since the macros seem to be completely unused, let's simply remove them so that nobody accidentially uses them in the future. And while we're at it, also remove the unused macro I40IW_CREATE_STAG. Signed-off-by:

The SQ head is incorrectly incremented when the number of WQEs required is greater than the number available. The fix is to use the I40IW_RING_MOV_HEAD_BY_COUNT macro. This checks for the SQ full condition first and only if SQ has room for the request, then we move the head appropriately. Signed-off-by:
