Bryan Whitehead dd9d9f5907 lan743x: Fix RX Kernel Panic ... It has been noticed that running the speed test at www.speedtest.net occasionally causes a kernel panic. Investigation revealed that under this test RX buffer allocation sometimes fails and returns NULL. But the lan743x driver did not handle this case. This patch fixes this issue by attempting to allocate a buffer before sending the new rx packet to the OS. If the allocation fails then the new rx packet is dropped and the existing buffer is reused in the DMA ring. Updates for v2: Additional 2 locations where allocation was not checked, has been changed to reuse existing buffer.
