The eui64.[ch] and ipv6cp.[ch] were taken from ppp-2.3.11. However, our stock pppd(8) doesn't provide option_t nor some utility functions. So, I made some hacks to adjust to our stock pppd(8). The sys_bsd.c part was taken from NetBSD with some modifications to adjust to our stock pppd(8). usr.sbin/pppd/Makefile: 1.31 usr.sbin/pppd/eui64.c: 1.2 usr.sbin/pppd/eui64.h: 1.1 usr.sbin/pppd/ipv6cp.c: 1.2 usr.sbin/pppd/ipv6cp.h: 1.2 usr.sbin/pppd/main.c: 1.22 usr.sbin/pppd/options.c: 1.25 usr.sbin/pppd/pathnames.h: 1.11 usr.sbin/pppd/pppd.8: 1.27 usr.sbin/pppd/pppd.h: 1.14 usr.sbin/pppd/sys-bsd.c: 1.21
