We can avoid the costly division for the common case where we pad the frame to tx_max size as long as we ensure that tx_max is either the device specified dwNtbOutMaxSize or not a multiplum of wMaxPacketSize. Using the preconverted 'maxpacket' field avoids converting wMaxPacketSize to CPU endianness for every transmitted frame And since we only will hit the one byte padding rule for short frames, we can drop testing the skb for tailroom. The change means that tx_max now represents the real maximum skb size, enabling us to allocate the correct size instead of always making room for one extra byte.
