This adds config option to specify static roles for master and slave in the Best Master Clock Algorithm. This is the case for Automotive Profile where networks are mostly static and role for each device is known in advance. masterOnly and slaveOnly will be used to determine the roles for the devices. Since masterOnly is a per-port config and slaveOnly is a global config option, role assignment will be slightly odd in case of bridges. If slaveOnly is set to 1, all the ports will be in slave roles except for the ones where masterOnly is set to 1. These ports will assume the master role. Two new FSMs which will be used for master and slave roles for this config option have also been added. Signed-off-by: Vedang Patel <vedang.patel@intel.com>
