RedPitaya authentication with 802.1x in wired networks via eth0

I searched Internet for a solution but I haven't found it, so I share it here. There is a simple way of configuring RedPitaya to connect it to a wired network which requires authentication by 802.1x. It is enough to add wired.conf file into: /etc/wpa_supplicant/ with the parameters provided by the network administrator and run a command as follows:

wpa_supplicant -i eth0 -D wired -c /etc/wpa_supplicant/wired.conf -B

An example of wired.conf file:

ctrl_interface=/run/wpa_supplicant

ap_scan=0

network={
        eapol_flags=0
        key_mgmt=IEEE8021X
        eap=TTLS
        phase2="auth=PAP"
        identity="MyUserId"
        anonymous_identity="MyUserId"
        password="MyPassword"
        priority=80
}  

Red Pitaya output noise

Recently I've found very interesting post Adding voltage regulators for the RedPitaya output stage. As I'm using Red Pitaya I decided to analyse the problem with my 14bit Red Pitaya. I performed measurements similar to the one published by lneuhaus. Result you can see below.

Pitaya was supplied by a lab power supply as the switching adapter introduces relevant noise components to the generated signal. Noise was measured during generation of a weak note (10mVpp) at 1MHz. Output noise in the low frequency region decreased substantially after removing resistors. Exact procedure of the mod and the problem analysis are in the original post.
