From 3e99df87722874c669f6c24a79bd1b4ba5fec819 Mon Sep 17 00:00:00 2001 From: Shahar Klein Date: Sun, 18 Mar 2018 09:02:06 +0200 Subject: [PATCH] net/mlx5: Add source e-switch owner The source e-switch owner allows a vport on one e-switch port be associated with a rule defined on the second port e-switch. The role of the source eswitch owner valid bit in the flow group is to allow the firmware fail driver attempts to wild card the source eswitch match field. If this bit is not set, the firmware ignores the source eswitch owner field totally.
