Subject: Update Probe Response template on BSS color change
X-Git-Tag: hostap_2_11~121
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=51b5b9512ffbf74aff99232425237da5229a0261;p=thirdparty%2Fhostap.git

Update Probe Response template on BSS color change

When AP is beaconing only on the 6 GHz band and unsol_bcast_presp
interval is set, AP sends unsolicited broadcast Probe Response frames
for in-band discovery. hostapd sent the Probe Response template for this
frame only when setting a new Beacon frame template.

Extend this to update the Probe Response template during BSS color
change.
