Subject: Hook netlink interface notification up to fwk.
X-Git-Tag: android-x86-7.1-r1~578
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=67c5753274ee828b56f96b5e9cdae64c8562ad52;p=android-x86%2Fsystem-netd.git

Hook netlink interface notification up to fwk.

The java api was there to get callbacks but the middle piece was missing.
Also has one const defined for USB control that is part of a seperate change, but no harm.
