Subject: [PATCH 4.19 084/639] ipv6: add missing tx timestamping on IPPROTO_RAW

From: Willem de Bruijn <willemb@...gle.com>

[ Upstream commit fbfb2321e950918b430e7225546296b2dcadf725 ]

Raw sockets support tx timestamping, but one case is missing.

IPPROTO_RAW takes a separate packet construction path. raw_send_hdrinc
has an explicit call to sock_tx_timestamp, but rawv6_send_hdrinc does
not. Add it.

Fixes: 11878b40ed5c ("net-timestamp: SOCK_RAW and PING timestamping")
