    lldpd: bump to 1.0.20
    
    Also implemented the med fast-start -> lldp fast-start change.
    lldpd includes a backwards compat handler for the older med command,
    but it's better to make these changes so they align with documentation.
    
    Changes:
    https://github.com/lldpd/lldpd/releases/tag/1.0.20
    
    Changes:
        Enable fast start unconditionally (and move its configuration in "configure lldp")
        Make VLAN advertisements configurable
    Fix:
        Do not break zero-copy traffic on Linux
        Fix crash on rapid addition/removal of interfaces
        Fix management address selection when pattern is a negative IP address
