802.21 for IP handovers

Hello IPWAVErs,

José Santa Lozano commented that their implementation can rely on 802.21
(instead of WSA-with-WRA-field or RA) to realize IP handovers in 802.11-OCB.

The old text is this:
> One such message may be the 802.11p’s Time Advertisement, or higher
> layer messages such as the "Basic Safety Message" (in the US) or the
> "Cooperative Awareness Message " (in the EU), that are usually sent
> several times per second. Another alternative replacement for the
> IPv6 Router Advertisement may be the message ’WAVE Routing
> Advertisement’ (WRA), which is part of the WAVE Service
> Advertisement and which may contain optionally the transmitter
> location; this message is described in section 8.2.5 of
> [ieeep1609.3-D9-2010].

New, if at all:
> One such message may be the 802.11p’s Time Advertisement, or higher
> layer messages such as the "Basic Safety Message" (in the US) or the
> "Cooperative Awareness Message " (in the EU), that are usually sent
> several times per second. Another alternative replacement for the
> IPv6 Router Advertisement may be the message ’WAVE Routing
> Advertisement’ (WRA), which is part of the WAVE Service Advertisement
> and which may contain optionally the transmitter location; this
> message is described in section 8.2.5 of [ieeep1609.3-D9-2010].  Yet
> another alternative replacement for IPv6 RA is the involvement of
> 802.21 signal levels, or additional 802.21 entities,
