HW address abnormal in packet

[shawnyangcis]

Hello,
I am trying to capture packet using NetfilterQueue, and then analyse with Scapy. But the result was in mess. The real mac is, e.g.,8C:70:5A:8D:B2:90 in my pc, and 08:00:27:8C:55:A0 in my virtual machine.Yet it becomes like this in scapy output:

40:00:40:06:D8:F0 > 45:10:00:58:DE:07 (0xc0a8)
40:00:40:06:6D:42 > 45:10:00:80:49:8E (0xc0a8)
40:00:40:06:D9:13 > 45:10:00:34:DE:08 (0xc0a8)
40:00:40:06:D8:EE > 45:10:00:58:DE:09 (0xc0a8)

Environment:
ubuntu server 16.04
python3.5
