Hi Johannes,

We are using iwlwifi driver in Tizen IVI. We were using kernel v3.4 and
wifi tethering worked fine. But after upgrading to v3.5 it stopped
working.

I am trying to bisect this already many hours - very difficult, because
tethering did not work in kernels around v3.4-rcX for some different
reasons, so just 'git bisect' does not work.

OK, my latest finding is:
        
        bad:               3edaf3e Johannes Berg  mac80211: manage AP netdev carrier state
        good:              fe40cb6 Ashok Nagarajan  mac80211: Check basic rates when peering
        
However, just reverting in 3.5 does not solve the issue. I am out of
ideas how to proceed.

OK, finally I got it. After 3 days of hardcore intelligent bisecting
        I've found out that tethering in 3.5 works for me if I revert
these 2
        patches:
        
            56138f5 iwlwifi: dont pull too much payload in skb head
            3edaf3e mac80211: manage AP netdev carrier state
        
        Johannes, Eric?
