mac80211: move netif_carrier_on to after ieee80211_bss_info_change_notify
Putting netif_carrier_on before configuring the driver/device with the new association state may cause a race (tx frames may be sent before configuration is done) Signed-off-by: Guy Cohen <guy.cohen@intel.com> Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: John W.
