Static relay with fixed host address

This is a method of static relaying with a fixed upper address in a LayerTree network.

Set the members of the tsNwkLayerTreeConfig structure as follows.

sNwkLayerTreeConfig.u8StartOpt = 
    TOCONET_MOD_LAYERTREE_STARTOPT_FIXED_PARENT;
            // Do not scan at the start

sNwkLayerTreeConfig.u8ResumeOpt = 
    TOCONET_MOD_LAYERTREE_RESUMEOPT_NO_RELOCATE_ON_RESUME;			
            // Operate a fixed parent unit even when resuming

sNwkLayerTreeConfig.u32AddrHigherLayer = 0x80012345;
            // The node at 0x80012345 is the superior node.

If NB BEACON (TOCONET_MOD_LAYERTREE_STARTOPT_NB_BEACON) is specified, the fixed configuration address is enabled only when the NB beacon cannot determine the upper level.
