[PATCH 5.18 061/158] net: prestera: acl: use proper mask for port selector

From: Greg Kroah-Hartman
Date: Wed Jul 27 2022 - 13:35:49 EST


From: Maksym Glubokiy <maksym.glubokiy@xxxxxxxxxxx>

[ Upstream commit 1e20904e417738066b26490de2daf7ef3ed34483 ]

Adjusted as per packet processor documentation.
This allows to properly match 'indev' for clsact rules.

Fixes: 47327e198d42 ("net: prestera: acl: migrate to new vTCAM api")
