+Subject: tplink-safeloader: expand support list for TP-Link CPE210 v3
+
+This adds new strings to the support list for the TP-Link CPE210 v3
+that are supposed to work with the existing setup.
+
+Without it, the factory image won't be accepted by the vendor UI on
+these newer revisions.
+
+Tested on a CPE210 v3.20 (EU).
