Define and implement a nas-identifier-use-bssid config option
to include the BSSID in the NAS-Identifier attribute value of RADIUS packets.
This value defaults to 0, maintaining backwards compatibility, and is set to
the value 1 in the supplied hostapd.conf
This new configuration option works in combination with the
nas-identifier option.
Where the nas-identifier is unset, the default in hostapd.conf, the
BSSID will be used to populate this value in the form
“00-10-A4-23-19-C0” in all cases, irrespective of the value of
nas-identifier-use-bssid.
Omitting the NAS-Identifier in RADIUS packets causes significant
problems in the RADIUS protocol so this is not allowed to ever occur.
(Accounting-On and Accounting-Off forms of RADIUS accounting packets
are allowed to be sent in this case.)
Where the nas-identifier is set and the nas-identifier-use-bssid is
set to 1, the BSSID will be included in the value used for the
NAS-Identifier in the form “00-10-A4-23-19-C0:ap.example.com”.
(Accounting-On and Accounting-Off forms of RADIUS accounting packets
are allowed to be sent in this case.)
Where the nas-identifier is set and the nas-identifier-use-bssid is
set to 0, the BSSID will not be included in the value used for the
NAS-Identifier.
(Accounting-On and Accounting-Off forms of RADIUS accounting packets
will not be sent in this case.)
Range checks for nas-identifier now require this string value to be,
inclusive, between 3 and 104 characters in length.

From 0b728365eab4202755a1357de4aa7b118c7b0ff3 Mon Sep 17 00:00:00 2001
From: Nick Lowe <nick.lowe@xxxxxxxxxxxx>
Date: Sun, 28 Feb 2016 16:36:23 +0000
Subject: [PATCH] Define and implement a nas-identifier-use-bssid config option
to include the BSSID in the NAS-Identifier attribute value of RADIUS packets.
This value defaults to 0, maintaining backwards compatibility, and is set to
the value 1 in the supplied hostapd.conf
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This new configuration option works in combination with the nas-identifier option.
Where the nas-identifier is unset, the default in hostapd.conf, the BSSID will be used to populate this value in the form “00-10-A4-23-19-C0” in all cases, irrespective of the value of nas-identifier-use-bssid.
Omitting the NAS-Identifier in RADIUS packets causes significant problems in the RADIUS protocol so this is not allowed to ever occur.
(Accounting-On and Accounting-Off forms of RADIUS accounting packets are allowed to be sent in this case.)
Where the nas-identifier is set and the nas-identifier-use-bssid is set to 1, the BSSID will be included in the value used for the NAS-Identifier in the form “00-10-A4-23-19-C0:ap.example.com”.
(Accounting-On and Accounting-Off forms of RADIUS accounting packets are allowed to be sent in this case.)
Where the nas-identifier is set and the nas-identifier-use-bssid is set to 0, the BSSID will not be included in the value used for the NAS-Identifier.
(Accounting-On and Accounting-Off forms of RADIUS accounting packets will not be sent in this case.)
Range checks for nas-identifier now require this string value to be, inclusive, between 3 and 104 characters in length.
