This patch is still stuck in OpenWrt's patchwork. It is required to make the Archer C7 v5 flashable from the factory firmware's webinterface and I would consider it important for the Gluon v2018.2 release.
Currently flash from WebIF is broken for Archer C7 v5 EU models as their
SupportList entries are missing.
The added entries originate from TP-Links latest Archer C7 v5 EU
firmware.
