If\nskb allocation fails, keep on pulling packets out of the Rx DMA queue: we\nshouldn't break the polling immediately and thus falsely indicate to the\noctep_napi_poll() that the Rx pressure is going down. As there is no\nassociated skb in this case, don't process the packets and don't push them\nup the network stack - they are skipped.\n\nHelper function is implemented to unmmap/flush all the fragment buffers\nused by the dropped packet. 'alloc_failures' counter is incremented to\nmark the skb allocation error in driver statistics.\n\nFound by Linux Verification Center (linuxtesting.org) with SVACE."
