The tooltip shows "prp.enable", so you'd need to use "-o prp.enable:true".
Or you could enable it via Analyze -> Enabled Protocols -> PRP, which is normally how protocols are enabled/disabled. I find it a little strange that this dissector would have a separate preference to enable/disable it, but the comment in the source code indicates the following, so I guess this is the reason why:
/* Post dissectors (such as the trailer dissector for this protocol)
* get called for every single frame anyone loads into Wireshark.
* Since this protocol is not of general interest we disable this
* protocol by default.
*
* This is done separately from the disabled protocols list mainly so
* we can disable it by default. XXX Maybe there's a better way.

Subject: [Wireshark-users] Enable PRP dissector in tshark
Hello,
the switch to enable the PRP [0] dissector in wireshark can be found via "Edit -> Preferences -> PRP -> Enable dissector".
Does anyone know how to enable the PRP dissector with tshark?
Is it something like "-o prp:True" (which does not work, of course)?
