HSR devices can\nlive in network namespaces other than init_net.\n\nTwo async notifiers broadcast events with genlmsg_multicast(). They\nare hsr_nl_ringerror() and hsr_nl_nodedown(). That helper delivers\nonly on the default genl socket in init_net. So the events always land\nin init_net. The network namespace of the device does not matter.\n\nThis has two effects. A listener in the device's own namespace never\nsees its own ring error and node down events. A privileged listener in\ninit_net receives events from HSR devices in other namespaces. The\npayload carries the peer node MAC (HSR_A_NODE_ADDR) and the slave port\nifindex (HSR_A_IFINDEX).\n\nSwitch both callers to genlmsg_multicast_netns(). Other families with\n.netnsok = true already do this. Examples are gtp, ovpn, team,\nbatman-adv, netdev-genl, ethtool and handshake.\n\nhsr_nl_ringerror() already has the slave port. It uses\ndev_net(port->dev). hsr_nl_nodedown() takes the namespace from the\nmaster port via hsr_port_get_hsr()."
