  pf tests: Test ':0' ignoring link-local addresses
  
  Fix test: sys.netpfil.pf.pass_block.noalias
  
  Replace hard-coded epair0b with the variable holds the real epair interface
  used for testing.
  
  pf tests: Make pass_block:noalias more robust
  
  Send several ICMPv6 echo requests. We've seen occasional failures with a
  single request.
