selftests/net: ipv6 flowlabel
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")
