[PATCH 5.19 429/717] RDMA/irdma: Align AE id codes to correct flush code and event

From: Greg Kroah-Hartman
Date: Sat Oct 22 2022 - 06:28:33 EST


From: Sindhu-Devale <sindhu.devale@xxxxxxxxx>

[ Upstream commit 7f51a961f8c6b84752a48e950074a8c4a0808d91 ]

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.
