i'a using scapy and i have a problem with sending Eth packet :

>>>send(Ether(src="00:1e:8c:33:5c:d3", dst="00:22:5f:13:b0:53")/ARP())
WARNING: Mac address to reach destination not found. Using broadcast.

After that wireshark shows that some packet was send with src MAC set to 0 and dst set to broadcast. i've no idea why it's happening , some ideas ?
