OpenWrt 21.02 status

[Rich Brown]

>> 1) I created a new "Upgrading to OpenWrt 21.02.0" page at:	https://openwrt.org/playground/richb/to2102 I distilled the announcement page (https://openwrt.org/releases/21.02/notes-21.02.0) to make this checklist for people that won't read that entire page.
>> Did I get the new page right? Please feel free to edit and make it correct.
> 
> Yes looks good, we should probably integrate this somehow in the release notes, so that people do not have to read everything.

Thanks. I hasten to point out that I was just guessing / making stuff up in places. Please check every word, VERY CAREFULLY. (Remember, some readers will study it line by line. If it's not totally correct, they're going to do the wrong thing...)

>> 2) I was pretty fuzzy about what people should do if their target did migrate to DSA. Do we have a guide to help those people through the transition?

Then I think this is a big deal for people with interesting network configurations (maybe for everyone except those with a vanilla bridged LAN?) If they just install, I suspect they're going to be off the air, and we'll receive continuing "21.02 broke my router" complaints. Is this something we can detect automatically? 

In any event, we need to have good documentation about:
	- Whether or not you need to worry - either by examining LuCi or by examining /etc/config/network
	- How you make the transition from swconfig to DSA
	- How you recover if you made the switch and now want to get back to the same configuration

>> 3) Is there any OpenWrt document that describes how DSA affects the files in /etc/config and how it affects LuCI? Do we need to worry that a bunch of people will glibly upgrade, then be knocked off the air?

Maybe something like this? https://openwrt.org/playground/richb/dsa-mini-tutorial

It would be really great if Rafał (and others) could review the words on this page ASAP to make sure that a) I copy/pasted it correctly, and b) that the text is still correct.

Thanks.
