If the whole packet is\nshorter than ETH_HLEN, eth_type_trans() reads the header past the end\nof the data instead.\n\nPull at least ETH_HLEN, and drop the packet if that fails, which also\ndrops packets too short to hold an Ethernet header.  This also checks\nthe return value of the pull, which was ignored."
