Subject: [PATCH net-next 0/3] net/tcp-fastopen: Add new userspace API support

From: Wei Wang <weiwan@...gle.com>

The patch series is to add support for new userspace API for TCP fastopen
sockets. 
In the current code, user has to call sendto()/sendmsg() with special flag
MSG_FASTOPEN for TCP fastopen sockets. This API is quite different from the
normal TCP socket API and can be cumbersome for applications to make use
fastopen sockets.
So this new patch introduces a new way of using TCP fastopen sockets which
is similar to normal TCP sockets with a new sockopt TCP_FASTOPEN_CONNECT.
More details about it is described in the third patch.
(First 2 patches are preparations for the third patch.)

  net: Remove __sk_dst_reset() in tcp_v6_connect()
