RFC 8335 defines the network utility PROBE, which builds off of the
capabilities of Ping to query more detailed interface information from
networking nodes.
The definitions included in this patchset have been accepted into the
linux net-next branch and will be included in Linux 5.12. This
patchset adds the same definitions to the glibc for use in the
iputils package.
The relevant commits for the Linux definitions can be found here:
https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git/commit/?id=2b246b2569cd2ac6ff700d0dce56b8bae29b1842

These changes have been tested by running the glibc tests on x86_64

I'm a bit surprised how the EXT_* macros step outside of the general
ICMP namespace here.
And the ICMP_EXT_* macros seem to be for different PDU fields even
though they share a common prefix (ICMP_EXT_).
Thanks,
Florian
