This reverts commit 647862eb60c324015ea31293cc052558b5185ca4.
|
|
|
|
The second check of device_ap_sme looks like duplicated, but it isn't
|
|
actually. The trick is nl80211_create_monitor_interface may change that
|
|
variable value and the second evaluation may give a different result.
|
|
|
|
This definitely isn't a very clear code, but that change caused a
|
|
regression for drivers that:
|
|
1) Don't report NL80211_ATTR_DEVICE_AP_SME
|
|
2) Don't support monitor mode
|
|
3) Don't support subscribing for PROBE_REQ and/or ACTION frames
|
|
like brcmfmac. With such drivers hostapd doesn't start anymore.
