mlxsw: core: Trace EMAD events
Currently, mlxsw triggers the 'devlink:devlink_hwmsg' tracepoint whenever a request is sent to the device and whenever a response is received from it. However, the tracepoint is not triggered when an event (e.g., port up / down) is received from the device. Also trace EMAD events in order to log a more complete picture of all the exchanged hardware messages. Signed-off-by: Ido Schimmel <idosch@nvidia.com> Signed-off-by: David S.
