1. "Add sepolicy labeling of wifi.concurrent.interface" in property_contexts.
wlan1 interface is added first in Pie OS. And wlan1 interface has getIfaceName
by property_get in wifi_chip.cpp.
(/hardware/interface/wifi/1.2/default/wifi_chip.cpp)
But, there is no sepolicy about this interface. wlan0 and p2p0 is definitely specified.
So, if we try to use wlan1, native sepolicy violation occurs.
This is why this labeling is necessary.

2. wlan1: Property labeling same with wlan0 or p2p0.
wifi.interface u:object_r:exported_default_prop:s0 exact string

Test: Basic Sanity - Verified tethering by using wlan1
