Are you really sure the flag is IEEE80211_TX_INJECTED?
For the current (today, 22 May) wireless-testing, it seems it's been
 renamed to IEEE80211_TX_CTL_INJECTED. Also, not tx->flags anymore, but
 info->flags instead.
Can you confirm that?


I was going to say something else, but I saw another post by Johannes... Strange
that hostapd uses injection in monitor mode interfaces, I thought it would be
only  AP mode interfaces.
And it is also strange that iwlwifi developers wanted to disallow injection in
monitor mode, with hostapd apparently needing it!
