From 244faedfd4d8e8c8e9f3c628d29bb74196b49743 Mon Sep 17 00:00:00 2001 From: Raed Salem Date: Fri, 24 Apr 2020 12:45:05 -0700 Subject: net/mlx5: Refactor imm_inval_pkey field in cqe struct The imm_inval_pkey field can hold four different types of data, depends on the usage, the data could be one of the below: - Immediate field of the received message - Invalidate rkey - Pkey of the packet - Flow table metadata Current implementation doesn't reflect the intended usage of the field at usage time. Reflect the different types by replace this field with a union, modify code where this field is used to reflect its intended usage.
