    * We are comparing the path quality up to the node, and ignoring the link

-   *   1. because of the white bit, we assume that the 1-hop to the candidate
-   *      link is good (say, etx=1)
+   *   1. we expect this call only for links with white bit set

    *      1-hop quality to them (which means we are assuming it's 1 as well)
    *      This actually sets the bar a little higher for replacement
    *   3. this is faster
-   *   4. it doesn't require the link estimator to have stabilized on a link
