From bdf2fae8376bbf1bdb0baa4c3616e81731214dfb Mon Sep 17 00:00:00 2001 From: Arik Nemtsov Date: Thu, 30 Oct 2014 15:12:39 +0200 Subject: [PATCH] iwlwifi: ignore IBSS flag as regulatory NO-IR indication According to updated regulatory guidelines, the ACTIVE bit in the NVM also allows ibss activity on the channel. The IBSS NVM bit is not updated when LAR is active and is deprecated. Using this bit for NO-IR incorrectly causes all 5Ghz channels to be marked as passive.
