"Servo not initialized !!!!" after executing "ifconfig wriX down; ifconfig wriX up"

Configuration: slave on auto mode (not external port config) Problem: when on slave "ifconfig wriX down; ifconfig wriX up"is executed

• syslog prints: ERROR: __wrh_servo_update : Servo not initialized !!!!
• PTP state SLAVE is entered, but EXT state IDLE remains and PDETECT state is EXT_OFF

This does not occur when external port configuration is used
