Configuration reload not working

[Léo Serre]

Hello world,

I'm trying to change the configuration dynamically (without reboot).
I'm running hostapd v2.6 built using Buildroot on my device.

Hostapd is started from the `/etc/network/interfaces` using that rule: 
`post-up /usr/sbin/hostapd -B /etc/hostapd.conf -P /var/run/hostapd.pid`

Once started, I just change the ssid in the configuration file, and 
launched `kill -s SIGHUP 270` where 270 is my PID number.
I waited more than 5 minutes without viewing any changes on the SSID.

Also, I tried with `hostapd_cli reconfigure` which returns `Unknown 
command 'reconfigure'`

Here is my config file for information:

     # Net interface
     interface=mlan0

     # Driver selection (works with mwifiex
     driver=nl80211

     # SSID used
     ssid=WifiDINO

     # Use of 802.11g base frequency (2.4GHz)
     hw_mode=g

     # Channel used
     channel=8

     # Enable 802.11n
     ieee80211n=1

     # Use WPA2
     wpa=2

     # Set WPA2 password
     wpa_passphrase=MichelMichel!

     # Use CCMP
     rsn_pairwise=CCMP

     ctrl_interface=/var/run/hostapd

Thank you for your help,
