No need to define a dedicated field for padding, you can directly update the function Len() by adding the corresponding length to meet the minimum frame length requirement of 64 bytes..
| a.IPDst = make([]byte, a.ProtoLength) | ||
| copy(a.IPDst, data[n:n+int(a.ProtoLength)]) | ||
| n += int(a.ProtoLength) | ||
| if len(data[n:]) > 0 { |

ditto. No need to copy the "padding" bytes, since it is not a valid case that a component consumes the padding bytes.

Fix the ARP packet parsing code to adapt to the scenario where the switch adds extra padding bytes to ARP packets to meet the 64-byte minimum frame size.
