Subject: pppol2tp.c add '#ifdef INET6' for optional ipv6
X-Git-Tag: ppp-2.5.0~52^2
X-Git-Url: https://git.ozlabs.org/?a=commitdiff_plain;h=44a70d6f9eb6d1843868da1d45de382134a03630;p=ppp.git

pppol2tp.c add '#ifdef INET6' for optional ipv6

Without it, l2tp daemon can't launch ppp, cuz undefined symbol ipv6_up_notifier.
