xilinx_ethlite: fix eth_can_rx() for ping-pong
The eth_can_rx() function only checks the first buffers status ("ping"). The controller should be able to receive into "pong" when ping-pong is enabled. Checks the active buffer (either "ping" or "pong") when determining can_rx() rather than just testing "ping". Signed-off-by: Peter Crosthwaite <peter.crosthwaite@xilinx.com> Signed-off-by: Edgar E.
