NLIP CRC is placed differently depending if receiving or sending?

[5frank]

If I understand it correctly, the 16-bit NLIP CRC is placed differently depending if receiving or sending. Just wanted to check if this is intentional? i.e. is it a feature or a bug? :) Changing it would probably break things but current state also complicates how NLIP can be used.
