Is there a way to reliably map radioA IDs from wireless UCI config to phyB IDs? I don't really want to assume that radio0 is phy0 and radio1 is phy1 unless this is guaranteed to be correct.

look at the /etc/config/wireless radioA config and see what /sys/* phy it's
configured to use.

I don't seam to see any things relating to sys or phy in the UCI config.

these are running various versions of LEDE and OpenWRT
on my Turris, I have:

My /etc/config/wireless starts with these lines:
config wifi-device radio0 option type mac80211 option phy phy0 option channel auto
If I type uci show wireless in the CLI, I see these lines listed:
wireless.radio0=wifi-device wireless.radio0.type='mac80211' wireless.radio0.phy='phy0' wireless.radio0.channel='auto'
This lets you manually tie devices to phys. The UCI entry only shows up if the /etc/config/wireless file explicitly sets the mapping.
The other option is to find the mapping from the ifname to the phy. E.g. If you want to know what wlan0 is connected to:
# cat /sys/class/net/wlan0/phy80211/name phy0
This might be what I need - I'll take a look into this. Thanks.
Will the final option allow you to match radios with phys?
Yes, but it's somewhat complicated and a bit fragile. From uci show wireless you should see these lines:
wireless.@wifi-iface[0].device='radio0' wireless.@wifi-iface[0].network='wlan'
So if you look up wlan in the network file, it should have something like this
config interface 'wlan' option proto 'dhcp' option ifname 'wlan0'
and then listing uci show network.wlan should show you:
network.wlan=interface network.wlan.proto='dhcp' network.wlan.ifname='wlan0'
So you have to follow the trail from radio0 to network wlan to ifname wlan0 and then use that to look up the phy. This is fragile in that it requires the config to be explicitly captured in the config files. The problem is that it appears that radio0 is not really a concept outside of the config scripts, so the rest of the system does not recognize it.
If you can do without radio, and only deal with ifname (like wlan0) and phy, life will be simpler.
