	Ping sockets don't appear to make any attempt to preserve flow labels created and set by userspace using IPV6_FLOWINFO_SEND. Instead they are clobbered by autolabels (if enabled) or zero. Grab the flowlabel out of the msghdr similar to how rawv6_sendmsg does it and move the memset up so it doesn't get zeroed after.

2019-05-28	selftests/net: ipv6 flowlabel	Willem de Bruijn	1	-0/+21
	Test the IPv6 flowlabel control and datapath interfaces: Acquire and release the right to use flowlabels with socket option IPV6_FLOWLABEL_MGR. Then configure flowlabels on send and read them on recv with cmsg IPV6_FLOWINFO. Also verify auto-flowlabel if not explicitly set. This helped identify the issue fixed in commit 95c169251bf73 ("ipv6: invert flowlabel sharing check in process and user mode") Signed-off-by: Willem de Bruijn <willemb@google.com> Signed-off-by: David S.
