Lost IP head in sended net packet

Hello,we use DM8168 with RDK 4.0,
we encounted a problem in ethernet:

the sended net packet lost ip head,
we use wireshark cacth error net packet like this:
" 36 37 38 39 30 31 32 33 34 35 36 37 38 39 30 31
32 33 34 35 36 37 38 39 30 31 32 33 34 35 36 37
38 39 30 31 32 33 34 35 36 37 38 39 30 31 32 33
34 35 36 37 38 39 30 31 32 33 34 35 36 37 38 39
2e 30 2d 34 35 34 34 2e 30 20 73 65 63 20 20 34
2e 30 31 20 47 42 79 74 65 73 20 20 33 34 2e 35
20 47 62 69 74 73 2f 73 65 63 0d 0a "
but the right net packet link this,
" 00 06 f6 7b 9c c8 90 59 af 45 f4 8c 08 00 45 00
05 da 86 1c 40 00 40 11 c7 7a 0a 01 18 4c ac 10
19 1f 81 60 13 89 05 c6 3a 3b 00 00 00 5d 54 89
45 0e 00 08 98 6b 00 00 00 00 00 00 00 01 00 00
13 89 00 00 00 00 05 5d 4a 80 ff 67 69 80 36 37
38 39 30 31 32 33 34 35 36 37 38 39 30 31 32 33
34 35 36 37 38 39 30 31 32 33 34 35 36 37 38 39
30 31 32 33 34 35 36 37 38 39 30 31 32 33 34 35
36 37 38 39 30 31 32 33 34 35 36 37 38 39 30 31
32 33 34 35 36 37 38 39 30 31 32 33 34 35 36 37 "
clear,the error net packet lost 78 bytes ip head.
