Included changes:
- substitute FSF address with URL - deselect current bat-GW when GW-client mode gets deactivated - send every DHCP packet using bat-unicast messages when GW-client mode is enabled - implement the Extended Isolation mechanism (it is an enhancement of the already existing batman-AP-isolation). This mechanism allows the user to drop packets exchanged by selected clients by using netfilter marks. - fix typ0 in header guard - minor code cleanups -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQIcBAABCAAGBQJSzk9EAAoJEEKTMo6mOh1VT9UP/0Mdcg7VM7oKSUEkUszAAQsW HwYVxFo89bwxMVauv4qAnmC6J4mV1IeciXFnpTeon8Bqr7isRDz8gCpDV/6m9AZp Rh3PFEWkJEE7xZy2sSOyn2cZrgP/Wd/zYTxac+XAf0I+cjSYo40vGGc1/9/EN7to lo1A4ru+BQJvQkt500a859Z5PAAsVXolYtLqJcxD0eGDbzR1kHTQmUDJEEkNwzUP 55vLu1KsSbYxw/T4A8ABKwCvkGRTJhgKmKKvwymeH9PHc5ODAZeInw1HTupKwIOQ W+WJxksJ0oBEuZB7y2NVXBRyPC2bF3D10C/7yZlul0PEntmT8vWV/eeO+Lw59YS3 rzFi+wpvdHwkjuBKpr+mc8lMPE0nWU31HqpFJP3y5IzsjL31kWT6sioWHxhY1zo9 hvZpb2/F8BniSgT5o3vpMcfInBQefViXP6ELjyB5i6+z2Pf8TqPukNGxCEWpOF6O r8HUHlPjbwERohK8/x4LRA8F7VpNagvMJ8kSHRUeR1j5QfcpbqFj3xi5LEBciakT WHok0AJdNrFUBVuj2n9z0hHFTTGF4Yxqf61A/vHJkROEthqwvoqtTOX5L1c1ZC/f DV6q4m2mLWuUxuRLGVWlXoN2XK8min+Of4RABzicX47EUIjTiPHOh38oymQUXG7D FS7/kYo5ZMIJmJgNKp+4 =6EjB -----END PGP SIGNATURE----- Merge tag 'batman-adv-for-davem' of git://git.open-mesh.org/linux-merge Included changes: - substitute FSF address with URL - deselect current bat-GW when GW-client mode gets deactivated - send every DHCP packet using bat-unicast messages when GW-client mode is enabled - implement the Extended Isolation mechanism (it is an enhancement of the already existing batman-AP-isolation).
