Constant BPF_F_NO_COMMON_LRU

pub const BPF_F_NO_COMMON_LRU: i32 = _; // 2i32

Available on crate feature dep_nc only.

Instead of having one common LRU list in the BPF_MAP_TYPE_LRU_[PERCPU_] HASH map, use a percpu LRU list which can scale and perform better.

Note, the LRU nodes (including free nodes) cannot be moved across different LRU lists.
