    cxgbetool(8): Add support for setting the hashfilter mode (filter mask).
    
    Tighten up the validation of filter modes while here.  Unrecognized
    keywords will be now be flagged as errors instead of being ignored.
    
    (cherry picked from commit 038148c108c4e7251c52364616273eec72b0c061)
