    BUG/MINOR: stick-table: Use MAX_SESS_STKCTR as the max track ID during parsing
    
    During the parsing of the sc-inc-gpc0, sc-inc-gpc1 and sc-inc-gpt1 actions, the
    maximum stick table track ID allowed is tested against ACT_ACTION_TRK_SCMAX. It
    is the action number and not the maximum number of stick counters. Instead,
    MAX_SESS_STKCTR must be used.
    
    This patch must be backported to all stable versions.
