net-next commit 971a351ccbbd2b6eef136a2221da0b80aca50906 Author: Jiri Pirko jiri@resnulli.us Date: Tue Dec 10 13:56:29 2013 +0100

ipv6 addrconf: revert /proc/net/if_inet6 ifa_flag format

Turned out that applications like ifconfig do not handle the change. So revert ifa_flag format back to 2-letter hex value.

Introduced by: commit 479840ffdbe4242e8a25349218c8e0859223aa35 "ipv6 addrconf: extend ifa_flags to u32"
