From edac6f6332d96aab59af5f27a195f55cd080f034 Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Mon, 26 Jul 2021 19:55:36 +0300 Subject: Revert "net: dsa: Allow drivers to filter packets they can decode source port from" This reverts commit cc1939e4b3aaf534fb2f3706820012036825731c. Currently 2 classes of DSA drivers are able to send/receive packets directly through the DSA master: - drivers with DSA_TAG_PROTO_NONE - sja1105 Now that sja1105 has gained the ability to perform traffic termination even under the tricky case (VLAN-aware bridge), and that is much more functional (we can perform VLAN-aware bridging with foreign interfaces), there is no reason to keep this code in the receive path of the network core. So delete it. Signed-off-by: Vladimir Oltean Signed-off-by: David S.
