Hi Tengfei,

Thank you for the updates. The new version addresses my comments. Here
are a couple of trivial comments:

> (Section 5.1)
>    The node MUST maintain the following counters for the selected parent
>    on both negotiated Tx and Rx cells:

To my understanding, we have separate pairs of NumCellsElapsed and
NumCellsUsed for the negotiated TX cell and the negotiated RX cell. It
would be better to modify the sentence a little bit like:

--> "The node MUST maintain the following counters for each of the
negotiated Tx cells, and the negotiated RX cells, that are scheduled
with the selected parent."

> (Section 5.3)
>    2.  For example, when MAX_NUMTX is set to 256, from NumTx=255 and

--> "..., when MAX_NUMTX is set to 255, ..."
