DESCRIPTION: This function builds an ARP Response template to set to
the HAL when joining an infrastructure network.
The function's steps:
- It builds the template & set the template len.
- If QoS is inactive, it discards the QoS Control Field.
** The template type is set in the site mgr.
INPUT: pSiteMgr - Handle to site manager.
pTemplate - Pointer to the template structure.
OUTPUT:
RETURN: TI_OK
