[PATCH v2 0/4] Assorted fixes, address a static checker warning

[Stefano Brivio <sbrivio@redhat.com>]

These are small assorted fixes and a change to address a static checker
warning I had on my list for a while but never found the time to polish
up for sending.

So here they are. There's no particular relationship between patches,
they are actually independent changes.

v2: Changes suggested by David in 2/4 and 4/4, while 1/4 and 3/4 are
    unchanged

Stefano Brivio (4):
  CONTRIBUTING.md: The tag is "Link:", regardless of how many we have
  dhcp: Make option parsing more robust, explicitly handle options 0 and
    255
  passt.1, pesto.1: ::1 is an address, not a port
  ndp: Use high quality entropy in NDP timer even if not needed
