parentRDMA/core: Add interface to read device namespace sharing mode (diff)
RDMA/core: Add command to set ib_core device net namspace sharing mode
Add netlink command that enables/disables sharing rdma device among multiple net namespaces. Using rdma tool, $rdma sys set netns shared (default mode) When rdma subsystem netns mode is set to shared mode, rdma devices will be accessible in all net namespaces. Using rdma tool, $rdma sys set netns exclusive When rdma subsystem netns mode is set to exclusive mode, devices will be accessible in only one net namespace at any given point of time. If there are any net namespaces other than default init_net exists, while executing this command, it will fail and mode cannot be changed. To change this mode, netlink command is used instead of sysctl, because netlink command allows to auto load a module.
