Yotam, did you run the test i proposed? I am worried about the TLV one.
Note:
Encoder includes the length of the TLV header length in the L part.
If you are reaching a conclusion that you need this in the decoding:
+		tlvdata += alen + sizeof(struct meta_tlvhdr);

then very likely whoever is sending that packet is not encoding
correctly.

cheers,
