From 23ce0bb922cd59694c03b329df5be051d42f5a7b Mon Sep 17 00:00:00 2001 From: Enrico Mioso Date: Fri, 11 Feb 2022 10:46:00 +0100 Subject: [PATCH] ipq40xx: limit available radio channels for GL.iNet GL-B2200 The PCIe and built-in 5GHZ radios are meant to operate on different frequency bands. The hardware enforces this via RF filters. Add this information to allow software enforcing it as well. Credits to Piotr Dymacz for the invaluable help.
