I've asked me the same question, but as it stands FC-LS only allows for
two frame types (LS_ACC or LS_RJT).
And it's (more-or-less) consistent usage throughout libfc.
But yeah, for safety one really should check for LS_ACC and LS_RJT and
throw an error for any other type.
However, that should be done throughout libfc, and would warrant a
different patch.
