Hello dear maintainers of the Sockets API in Ruby,

I am currently writing a traceroute-like program. I would like to write
it in Ruby. Among other things, this should generate ICMP error
messages via "UDP pings" with a low TTL. I would like to view these in
Ruby. For IPv4 there is the `Socket::IP_RECVERR` flag and for IPv6 the
`IPV6_RECVERR` flag. Unfortunately, this is not included in Ruby for
IPv6. The same applies to MTU discovery: `Socket::IP_MTU_DISCOVER`
exists, but `Socket::IPV6_MTU_DISCOVER` does not. I then reported the
error [1]. After I had dealt with the topic a bit, I also put a PR [2]
on GitHub.

I now wanted to ask whether my PR [2] can receive a review and then be
merged?

Regards
Marek K=C3=BCthe
