wpa_supplicant 2.3 and AP band steering

Hi,

I am using a linux driver for the D-Link DWA-171 device
(https://github.com/gnab/rtl8812au) and I am experiencing problems with that
my client (a Raspberry PI) ignores part of my wpa_supplicant.conf file. In
particular, it is the scan_freq and freq_list parts which not are working as
expected. The problem is that the access points force my client to connect
on 5Ghz (band steering). The same problem was present on wpa_supplicant 2.2.
However, if I use a WiFi device which can utilize the nl80211 driver, it
works perfect.

Any advice ?
