[Error when using example code ] argument for 's' must be a bytes object

[Mark4551124015]

when doing 'pak.serialize()' in dhcp.py _send_packet()
argument for 's' must be a bytes object

[EricLee543]

The message in this exception says that you did not make your packet in bytes format. Probably, you used string instead of bytes when you wrote the information when building the packet

fixed，options in dhcp need to be encode in bytes
