If radar was detected single BSS is notified about it. This caused only
that single BSS to be stopped and restarted. However, due to nl80211
interface combinations the BSS was not started on a new channel and
other BSSes remained operating on the old channel.
The downside is that hostapd_disable_iface() causes deauth frames to be
sent. This is undesired but on the other hand it doesn't make sense to
create workarounds that imitate CSA's 'block tx'. For proper Tx
quiescing CSA should be properly implemented.

The GTK rekey offload information was sent to the driver immediately
after the 4-way handshake which ended up being before the initial group
key exchange in the case of WPA (v1). This could result in even that
initial GTK handshake being offloaded and wpa_supplicant being left in
WPA_GROUP_HANDSHAKE state. Fix this by postponing the operation to
happen only after the full set of initial EAPOL-Key exchanges have been
completed (i.e., in the existing location for WPA2 and a after the group
key handshake for WPA).

This provides a new option for configuring multiple virtual interfaces
(BSS) that share a single radio. The new command line parameter
-b<phyname>:<config file name> is used to define one or more virtual
interfaces for each PHY. The first such entry for a new PHY is used to
initialize the interface structure and all consecutive parameters that
have the same PHY name will be added as virtual BSS entries to that
interface. The radio parameters in the configuration files have to be
identical.
This can be used as an alternative for the bss=<ifname> separator and
multiple BSSes in a single configuration file design while still
allowing hostapd to control the PHY (struct hostapd_iface) as a group of
virtual interfaces (struct hostapd_data) so that common radio operations
like OLBC detection and HT40 co-ex scans can be done only once per real
radio.
