[openwrt/luci] Changing disassoc_low_ack wireless settings breaks 5g wireless [X5000R]

Steps to reproduce:

1. Network -> Wireless -> Edit a 5g SSID
2. Interface Configuration -> Advanced
3. Uncheck ‘Disassociate On Low Acknowledgement’
4. Save & apply

Actual behavior:

Changes show the following:

# /etc/config/wireless
uci del wireless.radio1.band
uci del wireless.radio1.channel
uci add wireless.wifinet4.disassoc_low_ack='0'

Applying the changes disables wireless. Trying to edit the network again gives an error

TypeError
Cannot read properties of undefined (reading 'value')

This may be related to #5468

Expected behavior:

Example: Replace the following lines and remove this wireless.radio1.band and wireless.radio1.channel should not be deleted.

This is caused by a too old libiwinfo in OpenWrt base which does not understand the new option path ...+1 syntax used to identify the 5GHz radio phy. This has all sorts of weird side effects, like not being to identify the available operation modes, frequencies and so on.

I backported libiwinfo updates into the openwrt-21.02 branch now, the autobuilders will pick those up eventually and push new package versions to the binary repos. To fix the issue, you can then upgrade libiwinfo20210430 via opkg.

OpenWrt 21.02.4 will contain the updated package directly then.

21.02.3 with upgraded packages is working.
