^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29)     Valid flags:

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31)     -  0 - normal tune mode
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33)     -  ``FE_TUNE_MODE_ONESHOT`` - When set, this flag will disable any
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34)        zigzagging or other "normal" tuning behaviour. Additionally,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35)        there will be no automatic monitoring of the lock status, and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 36)        hence no frontend events will be generated. If a frontend device
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37)        is closed, this flag will be automatically turned off when the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 38)        device is reopened read-write.
