| This patch addresses changes made by usage of new symbols |
| like unregister_netdevice_queue() which are not possible to backport |
| due to their reliance on internal symbols on net/core/dev.c |
| |
| The patch that introduced this on mac80211 was: |
| |
| mac80211: Speedup ieee80211_remove_interfaces() |
