From b28f872dc48a4d55cba9d51cf3bac03ca32b2747 Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Thu, 26 Apr 2018 21:56:44 -0400 Subject: [PATCH] net: dsa: mv88e6xxx: move trunk setup Move the trunking setup out of Global 2 specific setup into the top level mv88e6xxx_setup function. Note that the 88E6390 family calls this LAG instead of Trunk and supports 32 possible ID routing vectors, with LAG ID bit 4 being placed in Global 2 register 0x1D... We don't need Trunk (or LAG) IDs for the moment, thus keep it simple. Signed-off-by: Vivien Didelot Signed-off-by: David S.
