From 50f32e2d1044b1f1658a1e40c8831969a30ca6a1 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Thu, 20 Aug 2015 00:16:42 +0200 Subject: brcmfmac: check all combinations when setting wiphy's addresses MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Broadcom is working on better reflection of interface combinations. With upcoming patches we may have 1st combination supporting less interfaces than others. To don't run out of addresses check all combinations to find the one with the greatest max_interfaces value.
