*
* Note(s) : (1) When NET_NIC_CFG_RD_WR_SEL configured to NET_NIC_RD_WR_SEL_MACRO, implement NIC read/write
*               functionality with macro's.
*
*               (a) The developer MUST implement the NIC read/write macro functions with the correct number
*                   & type of arguments necessary to implement the NIC's read/write functionality.
*
*               (b) The developer SHOULD appropriately name the NIC read/write macro functions by appending
*                   the number of bits that the macro functions read/write to the end of the macro function
*                   name :
*
*                           NetNIC_Rd_xx()
*                           NetNIC_Wr_xx()
*
*                   For example, 16-bit read/write macro functions should be named :
*
*                           NetNIC_Rd_16()
*                           NetNIC_Wr_16()
*
*
*               See also 'net_bsp.c  NetNIC_Rd_xx()  Note #1'
*                      & 'net_bsp.c  NetNIC_Wr_xx()  Note #1'.
