[2.6 beta1 w/ dco]Remove link-mtu warning.

[Originalimoc]

Identical --cipher/--data-cipher AES-128-GCM/--auth SHA256/--data-cipher-fallback/compression no setting among server and clients, no link-mtu config.

Client still log:
WARNING: 'link-mtu' is used inconsistently, local='link-mtu 1516', remote='link-mtu 1513'

Lack of documentation on how it's computed, and no real effect, DEPRECATED anyway, just remove it.

[Originalimoc]

Looks like it's internally auto-generated [src/openvpn/options.c]. I think the solution is removing this option as soon as possible as 2.6 is still in early beta?

[Originalimoc]

It's directly affecting 7 src files... Wonder what's the point of this at the beginning

[schwabe]

We need more information of your configuration. Normally if all is identical we should have not have these warnings.

Btw: Just because you do not see point or where the warning come from, does not mean that they are/were pointless. Your wording feels extremely agressive/insulting to me.

[Originalimoc]

yes weird indeed, wait.

I didn't say they are/were pointless, where the impression comes from
extremely agressive/insulting?
????????
better?

where's that 3 bytes discrepancy coming from...

[schwabe]

Please don't use the bug tracker like a chat. There is no need to split your one message into four individual ones. Also please provide a verb 4 log from both client and server as that will show the computation. This is probably triggered by persist-key or persist-tun but I would like to see complete logs from client and server to test my theory

[Originalimoc]

Probably, I'll test it later.
Yeah. You just reminded me Github bug tracker will send an email every time, maybe that's annoying to some people?
How about opening the discussion section on this repo?

[schwabe]

This repository is only for reporting bug. If you want to discuss, there is http://forum.openvpn.net

[schwabe]

@Originalimoc I am still waiting for your log files.

Next workday.
