 *  \brief  Allocate packet buffer using a user provided pointer, the memory
 *   is expected to have already been allocated.
 *
 *   For ideal performance memory should be 4k aligned. If it is not 4K aligned
 *   then a temporary 4k aligned memory will be used to copy data to and from
 *   when writing and reading. This will negatively impact performance.
 *
 *   This API will overwrite p_packet->buffer_size, p_packet->p_buffer and
 *   p_packet->p_data fields in p_packet.
 *
 *   This API will not free any memory associated with p_packet->p_buffer and
 *   p_packet->p_data fields in p_packet.
 *   Common use case could be,
 *       1. Allocate memory to pointer
 *       2. Call ni_custom_packet_buffer_alloc() with allocated pointer.
 *       3. Use p_packet as required.
