Vasundhara Volam Jan. 18, 2019, 7:09 a.m. UTC
Add support for "driverinit" configuration mode value for devlink_port
configuration parameters. Add devlink_port_param_driverinit_value_set()
function to help the driver set the value to devlink_port.

Also, move the common code to __devlink_param_driverinit_value_set()
to be used by both device and port params.
