tcp: move inet->rx_dst_ifindex to sk->sk_rx_dst_ifindex
[ Upstream commit 0c0a5ef809f9150e9229e7b13e43183b681b7a39 ]
Increase cache locality by moving rx_dst_ifindex next to sk->sk_rx_dst
This is part of an effort to reduce cache line misses in TCP fast path.
This removes one cache line miss in early demux.
