I have the following capture from a network of two nodes using MIH 802.21
Protocol. I am using Wireshark Version 1.12.7 on Ubuntu 14.04 x64. The MIH
message seems to be OK in the binary format, however Wireshark considers it as
a malformed packet. Wireshark is not able to interpret after the TLV length
field of the Source MIHF ID TLV. So is it a problem in the protocol
serialization or Wireshark dissector itself?
>From the binary format: We have MIH header length of 8 Bytes which is
interpreted correctly by Wireshark. Then Source MIHF ID TLV is 1 + 1 + 12 = 14
Bytes. The same thing for the destination MIHF ID TLV = 14 Bytes. Then Link
Identifier List TLV comes which has TLV Type of (25 in Decimal or 0x19) and
length of zero. Finally Registration Code TLV which has TLV Type of (11 in
Decimal or 0xb) and length of one byte. The total size of this MIH frame is 41
Bytes.
