Subject: [PATCH v2 net-next 00/10] tcp: receive path optimizations

From: Eric Dumazet <edumazet@...gle.com>

This series aims to reduce cache line misses in RX path.

I am still working on better cache locality in tcp_sock but
this will wait few more weeks.

v2: Resent because v1 seems to have been lost.
    Added Soheil Acked-by, and added "net: annotate accesses to sk->sk_rx_queue_mapping"

Eric Dumazet (10):
  tcp: move inet->rx_dst_ifindex to sk->sk_rx_dst_ifindex
  ipv6: move inet6_sk(sk)->rx_dst_cookie to sk->sk_rx_dst_cookie
  net: avoid dirtying sk->sk_napi_id
  net: avoid dirtying sk->sk_rx_queue_mapping
  net: annotate accesses to sk->sk_rx_queue_mapping
  ipv6: annotate data races around np->min_hopcount
  ipv6: guard IPV6_MINHOPCOUNT with a static key
  ipv4: annotate data races arount inet->min_ttl
  ipv4: guard IP_MINTTL with a static key
  ipv6/tcp: small drop monitor changes
