That's more than I'm aware of. AFAIK, the only legal text keys an
initiator may send during FFP are InitiatorAlias, MaxRxDSL, SendTargets
and vendor (extension) keys - what are the remaining ones?

See above. IIRC (need to have a look at the spec again, though), most
operational params may not be (re-)negotiated during FFP, with the
exception of MaxRxDSL, which may be re-declared.
