Subject: Add in6addr_loopback
X-Git-Tag: RELEASE-0.5~2
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=faa1ed75e9f85b6acdb5b96f88376f9dbcb98282;p=unikraft%2Flibs%2Flwip.git

Add in6addr_loopback

Bind9 uses the in6addr_loopback symbol. We add this
symbol in a separate c file, in6addr_loopback.c.
