For small Ethernet frames with size less than minimum size 66 for HSR vs 60 for regular Ethernet frames, hsr driver currently doesn't pad the frame to make it minimum size. This results in incorrect LSDU size being populated in the HSR tag for these frames. Fix this by padding the frame to the minimum size applicable for HSR.
