- 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 -
