    network.subr: Fix infinite loop
    
    When setting up carp tunnel, using a password consisting of only the
    characters used as hexadecimal characters, i.e. abc-def, there will be
    an infinite loop in the shell function ifalias_af_common_handler().
    To circumvent this we test for " pass ".
