[IPv6]: Can not set the IPV6_PKTINFO option
The Linux manpage of ipv6(7) mentions the IPV6_PKTINFO option (and it is
defined in header
files), but there is no setsockopt support for it. Aliasing to IPV6_RECVPKTINFO
fixes this,
and checking datagram_recv_ctl() in net/ipv6/datagram.c confirms that this
works as
expected from the API.
