net: allow macvlans to move to net namespace
I cannot move a macvlan interface created on top of a bonding interface to a different namespace: % ip netns add dummy0 % ip link add link bond0 mac0 type macvlan % ip link set mac0 netns dummy0 RTNETLINK answers: Invalid argument % The problem seems to be that commit f9399814927a ("bonding: Don't allow bond devices to change network namespaces.") sets NETIF_F_NETNS_LOCAL on bonding interfaces, and commit 797f87f83b60 ("macvlan: fix netdev feature propagation from lower device") causes macvlan interfaces to inherit its features from the lower device. NETIF_F_NETNS_LOCAL should not be inherited from the lower device by a macvlan. Patch tested on 3.16.
