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.
