From b3589dfe02123a0d0ea82076a9f8ef84a46852c0 Mon Sep 17 00:00:00 2001 From: Hante Meuleman Date: Mon, 19 Sep 2016 12:09:51 +0100 Subject: [PATCH] brcmfmac: ignore 11d configuration errors 802.11d is not always supported by firmware anymore. Currently the AP configuration of 11d will cause an abort if the ioctl set is failing. This behavior is not correct and the error should be ignored.
