ramips-mt7621: sysupgrade rejects images with newer SUPPORT_VERSION

[azrdev]

Bug report

What is the problem?

I'm running a D-Link DIR-860L with the "testing" branch of freifunk darmstadt firmware.

Currently, the device runs about daily into an offline state, requiring a power cycle. serial log (below) shows two problems:

1. Config cannot be migrated from swconfig to DSA -- according to @blocktrron this is just not implemented yet
2. after the failed autoupdate, the device remains in a networking-down state, instead of coming back into normal operation with the old firmware.

Gluon Version:

ssh login prints

 OpenWrt 19.07-SNAPSHOT, r11354+22-ffd4452f8b

Site Configuration:

https://git.darmstadt.ccc.de/ffda/firmware/site apparently

Device dir-860l-b1 not supported by this image
Supported devices: dlink,dir-860l-b1 dir-860l-b1 - Image version mismatch: image 1.1, device 1.0. Please wipe config during upgrade (force required) or reinstall. Reason: Config cannot be migrated from swconfig to DSA
Image check failed.

Custom patches:

no patches / "stock" ffda firmware.
only modification apart from normal config mode usage is this snippet to use all ethernet ports as WAN:

$ cat /etc/rc.local
# Put your custom commands here that should be executed once
# the system init finished. By default this file does nothing.

if uci get network.client.ifname | grep -q 'eth0.1' ; then
        logger "LAN-ports on ff network, reconfiguring"
        uci set network.wan.ifname='eth0.2 eth0.1'
        uci set network.client.ifname='local-port bat0'
        uci commit network
        /etc/init.d/network restart
fi
exit 0

1. is still an ongoing issue
2. See autoupdater: execute sysupgrade test before network shutdown packages#248 for a potential fix / behavior improvement.
