From 65fa40276ac1318e75264e5a204547b57c2cf397 Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Thu, 14 Apr 2016 14:42:07 -0400 Subject: [PATCH] net: dsa: mv88e6xxx: unlock DSA and CPU ports Locking a port generates an hardware interrupt when a new SA address is received. This enables CPU directed learning, which is needed for 802.1X MAC authentication. To disable automatic learning on a port, the only configuration needed is to set its Port Association Vector to all zero. Clear PAV when SA learning should be disabled instead of locking a port.
