mac80211: reprogram in interface order
During reprogramming, mac80211 currently first adds all the channel contexts, then binds them to the vifs and then goes to reconfigure all the interfaces. Drivers might, perhaps implicitly, rely on the operation order for certain things that typically happen within a single function elsewhere in mac80211. To avoid problems with that, reorder the code in mac80211's restart/reprogramming to work fully within the interface loop so that the order of operations is like in normal operation. For iwlwifi, this fixes a firmware crash when reprogramming with an AP/GO interface active. Reported-by:David Spinadel <david.spinadel@intel.com> Signed-off-by:
