From d7205a90219ae93bb6ac87360a27ec3c6e242cd1 Mon Sep 17 00:00:00 2001 From: Jo-Philipp Wich Date: Sun, 6 Nov 2011 18:49:17 +0000 Subject: [PATCH] mac80211: change wireless ifname numbering schema Instead of simply counting up until we hit a free iface, group ifnames by wiphy so that the first wlanX on a phy gets the phy number and following ifaces an index-suffix, e.g. wlan0 for network 1 on phy 1 and wlan0-1 for network 2 on phy 1. This fixes state var confusion when operating multiple radios and allows to reliably take down and restart one radio only, even if the number of networks changes in between. This should, along with other changes in LuCI, fix #10335.
