        happen to HW. If DMA is in suspend state, no interrupt will
        occur for channel which leads to not calling of
	osd_receive_packet().

Fix:    Whenever there is rx buffer kernel memory allocation failure,
	desc will be updated with reserve buffer. This reserved RX buffer
	is already allocated at the time of eqos_open. Aim of same to
	make sure rx DMA always have buffer and not go in suspend state.

- Use binary operation to fetch required bit
  for necessity of checksum.
