Subject: interface: when interface properties change, reinitialise
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=632953a1582dceb3472ed459c03df1fbb5e0717b;p=project%2Fmdnsd.git

interface: when interface properties change, reinitialise

Without this, when the ip addresses on an interface changed it
would no longer interact correctly with the interface.

Addresses #20
