Commit d3432bf10f17 ("net: Support filtering interfaces on no master") in the kernel added support for filtering interfaces/neighbours that have no master interface. This patch completes it and adds this support to iproute2: 1. ip link show nomaster 2. ip address show nomaster 3. ip neighbour {show | flush} nomaster Signed-off-by: Lahav Schlesinger <lschlesinger@drivenets.com> --- v1 -> v2 Break long lines --- ip/ipaddress.c | 3 +++ ip/iplink.c | 1 + ip/ipneigh.c | 4 +++- man/man8/ip-address.8.in | 7 ++++++- man/man8/ip-link.8.in | 7 ++++++- man/man8/ip-neighbour.8 | 7 ++++++- 6 files changed, 25 insertions(+), 4 deletions(-) -- 2.17.1
