[ovs-dev] [PATCH] flow: Verify that tot_len >= ip_len in miniflow_extract().

miniflow_extract() uses the following quantities when it examines an IPv4 header: size, the number of bytes from the start of the IPv4 header onward ip_len, the number of bytes in the IPv4 header (from the IHL field) tot_len, same as size but taken from IPv4 header Total Length field
