Stop returning `CONNACK` or `DISCONNECT` to clients that sent malformed CONNECT packets.
|
|
|
|
- Only send `CONNACK` with reason code `frame_too_large` for MQTT-v5.0 when connecting if the protocol version field in CONNECT can be detected.
|
|
- Otherwise **DONOT** send any CONNACK or DISCONNECT packet.
