  Modified files:
    sys/netgraph         ng_pppoe.c 
  Log:
  The default value of net.graph.nonstandard_pppoe is changed to -1,
  which means "always stay in the standard mode of PPPoE operation
  regardless of any junk floating around."
  
  As the referenced PR stated clearly, the old default setting of 0
  was extremely dangerous because it opened a possibility for a
  spurious frame not only to put down a single PPPoE node running
  FreeBSD, but to plague *every* FreeBSD node in a PPPoE network in
  such a way that those nodes would keep poisoning each other until
  rebooted simultaneously.
