-Subject: [PATCH] fsl_qbman/usdpaa: Invalidate software portals before use
-
-Invalidate the cache for the software portals before using them
-since the portals are non coherent. This ensures that the core
-using the portal is seeing the most up to date information in
-case the cache contained older data. This is important during
-the cleanup phase if cleanup occurs on a differnt core than
-what the application was using.
