I wasn't planning on sumbitting v4 until I had some reasonable test
coverage. I haven't got much time to spend on adding test right now. I will
try to spend some on it over the next few weekends.

DHCP and SLAAC would be decent follow on features from the initial support
for static addressing. I think both of these were requested when I
initially proposed IPv6 support for u-boot.

If you're keen to contribute tests or DHCP/SLAAC I'd be happy to add them
to my series.

Hi Chris,

Thank you for refreshing the topic and rebasing. Are you planning to post a v4?
Besides tests, you had identified some gaps in previous series (DHCP, SLAAC, 
etc).
We are looking for having IPv6 in upstream, happy to fill in what will help it.

I've rebased my series against v2022.07 you can get the code from the
ipv6 branch of https://github.com/cpackham/u-boot.git

I've only lightly compile tested it so I've no idea if it's still functional

IPv6 support is definitely something I want to get landed in upstream
U-Boot.

It seemed to be fairly well received last time I posted the series. The
main thing lacking was tests. That's pretty much where things were at last
time I touched it. As usual life and work commitments have stopped me from
progressing it further.

In the meantime U-Boot's testing infrastructure has improved a lot which
should make adding the tests easier. I know there have been some more
changes in net that will conflict but not badly.

At $dayjob we have merged a newer u-boot version into our fork so I do have
something that is effectively a post state for the merge conflict to refer
to but it's not the broken out series that I'd like to submit.

I think I should be able to get the series rebased against master (or the
just released 2022.07 might be more useful as a base). I can probably get
that up on github in the next couple of days.

Dear Sergey Lapin,

In message 20110610114303.ga7...@build.ihdev.net you wrote:
 
 Is it possible to use u-boot's tftp client
 in v6-only setup?

No, this is not possible yet.

 If not, is there some known working tftp/ipv6 implementation?

No, there isn't.  At least none I know about.

We once submitted such a proposal to CELF, see
http://elinux.org/CELF_Project_Proposal/Add_IPV6_support_to_U-Boot

But it was not selected.

Best regards,

Wolfgang Denk
