Lawrence reported that git clone could make system crash on a Qualcomm ARM soc based device (DragonBoard, 1G memory without swap) running 64bit Debian. It's turned out the crash is related with rx skb allocation failure. git could consume more than 600MB anonymous memory. And system is in extremely memory shortage case. But driver didn't handle the rx allocation failure case. This patch doesn't submit skb to upper layer if rx skb allocation fails. Instead, it reuse the old skb for rx DMA again. It's more like drop the packets if system is in memory shortage case. With this change, git clone is OOMed instead of system crash.
