#define MAX_SEQ_MOD   G_GINT64_CONSTANT(4294967296)
 

Module number used to rotate sequence number for a channel if it overcomes MAX_SEQ_NO.

While Vortex Library is operating with a channel, it may happen a channel overcome MAX_SEQ_NO so channel sequence number is rotated using a modulo operation with MAX_SEQ_MOD which is just MAX_SEQ_NO plus 1 unit.
