Here are a few cleanups, preparation work for the new PM ops, and sysctl knobs. - Patch 1: reorg: move generic NL code used by all PMs to pm_netlink.c. - Patch 2: use kmemdup() instead of kmalloc + copy. - Patch 3: small cleanup to use pm var instead of msk->pm. - Patch 4: reorg: id_avail_bitmap is only used by the in-kernel PM. - Patch 5: use struct_group to easily reset a subset of PM data vars. - Patch 6: introduce the minimal skeleton for the new PM ops. - Patch 7: register in-kernel and userspace PM ops. - Patch 8: new net.mptcp.path_manager sysctl knob, deprecating pm_type. - Patch 9: map the new path_manager sysctl knob with pm_type. - Patch 10: map the old pm_type sysctl knob with path_manager. - Patch 11: new net.mptcp.available_path_managers sysctl knob. - Patch 12: new test to validate path_manager and pm_type mapping.
