Hostap-Patch causes strange behavior in scan results

[Vincent]

Hi,
I wrote a patch to give me feedback about ht and vht capabilities in
probe requests. (LEDE)

https://github.com/berlin-open-wireless-lab/patches-pending/blob/master/patches/hostap_patches/601-probe-mgmt.patch

I'm just adding

+			struct ieee80211_ht_capabilities ht_capab;
+			struct ieee80211_vht_capabilities vht_capab;

to struct ieee80211_mgmt in the beacon struct:

u.beacon.ht_capab

Now I made a scan and the result looks like this:

ESSID:""
ESSID:""
ESSID:""
ESSID:""
ESSID:""
ESSID:""
ESSID:""
ESSID:""
ESSID:"LEDE_50"

I have no idea what happens...
Can you give me some hints?
