From 01ef75a257fa82cd0f8577fb9cda847415d2f748 Mon Sep 17 00:00:00 2001 From: Steen Hegelund Date: Sat, 14 Jan 2023 14:42:37 +0100 Subject: [PATCH] net: microchip: vcap api: Always enable VCAP lookups This changes the VCAP lookups state to always be enabled so that it is possible to add "internal" VCAP rules that must be available even though the user has not yet enabled the VCAP chains via a TC matchall filter. The API callback to enable and disable VCAP lookups is therefore removed. Signed-off-by: Horatiu Vultur Signed-off-by: Steen Hegelund Signed-off-by: David S.
