From 98cdb480712320880d9d5d9db052990a9609427e Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Fri, 7 Sep 2018 11:09:02 -0700 Subject: net: dsa: Expose tagging protocol to user-space There is no way for user-space to know what a given DSA network device's tagging protocol is. Expose this information through a dsa/tagging attribute which reflects the tagging protocol currently in use. This is helpful for configuration (e.g: none behaves dramatically different wrt. bridges) as well as for packet capture tools when there is not a proper Ethernet type available.
