This  is HW configuration property, it does not belong to  datagram. Also for TX
channels,  parity could  be  two  kinds:  odd and even, for RX it is only
on/off.

Parity  is  not  the  only property that needs to be configured in HW,
following could be needed as well,
- label bit flipping (on or off)
- rate change (low / high)
-  label  filters  and  label  priority matching (this could be HoltIC
specific)

I  suppose  all  these  properties  are  configured  only  once, at interface
initialization.
