+Subject: [PATCH] brcmfmac: support firmware reporting 160 MHz channels
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+So far 160 MHz channels were treated as 20 MHz ones which was breaking
+support for 40/80 MHz due to the brcmf_construct_chaninfo() logic and
+its assumptions.
