tcp: add tcp_rx_skb_cache sysctl Instead of relying on rps_needed, it is safer to use a separate static key, since we do not want to enable TCP rx_skb_cache by default. This feature can cause huge increase of memory usage on hosts with millions of sockets. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
