From dba8fbc67ecd193590a72e960e9f5a6578b8bae6 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Wed, 29 Jun 2016 21:54:27 +0200 Subject: [PATCH] brcmfmac: support removing AP interfaces with "interface_remove" MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit New firmwares (e.g. 10.10.69.36 for BCM4366) support "interface_remove" for removing interfaces. Try to use this method on cfg80211 request. In case of older firmwares (e.g. 7.35.177.56 for BCM43602 as I tested) this will just result in firmware rejecting command and this won't change any behavior.
