     Possible layers are phy, mac, rlc, pdcp, rrc, nas, s1ap, x2ap, gtpu and
     all. The 'all' layer is used to address all the layers at the
     same time.

     field values:

     - 'level': the log level of each layer can be set to 'none',
     'error', 'info' or 'debug'. Use 'debug' to log all the messages.
     
     - 'max_size': set the maximum size of the hex dump. 0 means no
       hex dump. -1 means no limit.
