void EnableSrcMatch (bool aEnable)

Enables/disables source address match feature.

The source address match feature controls how the radio layer decides the "frame pending" bit for acks sent in

response to data request commands from children.

If disabled, the radio layer must set the "frame pending" on all acks to data request commands.

If enabled, the radio layer uses the source address match table to determine whether to set or clear the "frame

pending" bit in an ack to a data request command.

The source address match table provides the list of children for which there is a pending frame. Either a short

address or an extended/long address can be added to the source address match table.

Parameters

aEnable [in] Enable/disable source address match feature.
