As per pcap following is the hex dump of 64 byte ethernet packet (Delay Req).
0000 00 a0 a5 d4 44 80 00 0a 35 00 22 01 88 f7 01 02
0010 00 2c 18 00 00 00 00 00 00 00 00 00 00 00 00 00
0020 00 00 00 0a 35 ff fe 00 22 01 00 01 01 b9 01 7f
0030 00 00 00 00 00 00 00 00 00 00 20 2d 35 36 32 33
Last four bytes are CRC. I am not clear about TLV in PTP Delay request packet.
Thanks,
Raveendra

Looks like garbage (not a valid TLV) suffixed to the frame.
