Here is the code

dest_mac = "\xbb\xbb\xbb\xbb\xbb\xbb" # target mac address

# Ethernet Header
protocol = 0x0806 # 0x0806 for ARP
eth_hdr = struct.pack("!6s6sH", dest_mac, source_mac, protocol)
# ARP header
htype = 1 # Hardware_type ethernet
ptype = 0x0800 # Protocol type TCP
hlen = 6 # Hardware address Len
