New Revision: 357891
URL: https://svnweb.freebsd.org/changeset/base/357891

Log:
  Don't check the auth algorithm for GCM.
  
  The upstream OpenSSL changes only set the cipher for GCM since the
  authentication is redundant, and changes to OCF will soon remove the
  GCM authentication algorithm constants entirely for the same reason.
  In addition, ktls_create_session() already validates these fields and
  wouldn't pass down an invalid auth_algorithm value to any drivers or
  ktls backends.
