I believe the only useful documentation you'll get for that is the
RFC...

>From https://tools.ietf.org/html/rfc4861#section-4.2 :

<quote>
      Source link-layer address
                     The link-layer address of the interface from which
                     the Router Advertisement is sent.  Only used on
                     link layers that have addresses.  A router MAY omit
                     this option in order to enable inbound load sharing
                     across multiple link-layer addresses.

So you'd normally leave that on for ethernet interfaces.
