bnx2x: Memory allocation
Memory allocation - The CQE ring was allocated to the max size even for a chip that does not support it. Fixed to allocate according to the chip type to save memory - The rx_page_ring was not freed on driver unload Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
