Cover letter [PATCH net-next v3 0/2] ipv4: per-datagram IP_TOS and IP_TTL via sendmsg()

There is no way to set the IP_TOS field on a per-packet basis in IPv4, while IPv6 has such a mechanism. Therefore one has to fall back to the setsockopt() in case of IPv4.

Using the existing per-socket option is not convenient particularly in the situations where multiple threads have to use the same socket data requiring per-thread TOS values. In fact this would involve calling setsockopt() before sendmsg() every time.
