In order to allow users to develop their own BPF-based path manager, this patch defines a struct ops "mptcp_pm_ops" for an MPTCP path manager, which contains a set of interfaces. Currently only init() and release() interfaces are included, subsequent patches will add others step by step.
Add a set of functions to register, unregister, find and validate a given path manager struct ops.
"list" is used to add this path manager to mptcp_pm_list list when it is registered. "name" is used to identify this path manager. mptcp_pm_find() uses "name" to find a path manager on the list.
mptcp_pm_unregister is not used in this set, but will be invoked in .unreg of struct bpf_struct_ops. mptcp_pm_validate() will be invoked in .validate of struct bpf_struct_ops. That's why they are exported.
