If an skb to be transmitted is shorter than the minimum Ethernet frame length, we currently set the DMA descriptor length to the minimum but do not add zero-padding. This could result in leaking sensitive data. We also pass different lengths to dma_map_single() and dma_unmap_single(). Use skb_padto() to pad properly, before calling dma_map_single().
