Description

NDNLPv2 revision 8 defines:

If an incoming LpPacket contains an unknown LpHeaderField, the following rules apply:
if the unknown field is in range [800:959], and the two least significant bits are 00, the receive SHOULD ignore the field, and continue processing the packet;
otherwise, the receiver MUST drop the packet, but SHOULD NOT consider the link has an error.

However, ndn::lp::detail::FieldInfo::canIgnore is set to true if the two least significant bits are 01.
Also, the error message in this situation is unhelpful: it should indicate the TLV-TYPE code of the bad element.
