Subject: ndp: use IPv4 address list when comparing IPv4 addresses
X-Git-Url: http://git.openwrt.org/?p=project%2Fodhcpd.git;a=commitdiff_plain;h=94e65ee0aecf0749e64fb29b4532c614e7be86a8

ndp: use IPv4 address list when comparing IPv4 addresses

Use IPv4 address list in check_addr_updates which fixes possible segfault
as IPv6 address list was used by mistake.
