Linus Torvalds fc02cb2b37 Core: 
- Remove socket skb caches
 
  - Add a SO_RESERVE_MEM socket op to forward allocate buffer space
    and avoid memory accounting overhead on each message sent
 
  - Introduce managed neighbor entries - added by control plane and
    resolved by the kernel for use in acceleration paths (BPF / XDP
    right now, HW offload users will benefit as well)
 
  - Make neighbor eviction on link down controllable by userspace
    to work around WiFi networks with bad roaming implementations
 
  - vrf: Rework interaction with netfilter/conntrack
 
  - fq_codel: implement L4S style ce_threshold_ect1 marking
 
  - sch: Eliminate unnecessary RCU waits in mini_qdisc_pair_swap()
