If slave "sees" master via PLIP, it keeps itself in slave mode. May be I don't understand you right. Although the idea is not officially supported, it is interesting. Can you please draw your setup, since I don't understand it clearly? Bringing link state support for p2p interfaces is a TODO, although CARP is not going to be supported on p2p interfaces officially.
