Prior to initiating communication on a DFS channel, channel availability
check needs to be performed. During this period, the AP does not beacon.
Hence, no channel switch was allowed during this period. However, if a
user wishes to switch to a non-DFS channel during the potentially long
CAC period and start transmission immediately, there is no provision to
do that currently.
Extend the existing CHAN_SWITCH control interface command to allow
channel switch even when the AP is in CAC state. To do this, first
disable the interface to abort the CAC in progress and then configure
the interface with the new parameters and finally re-enable the
interface.

Currently, hapd->link is added to the MLD links list during driver
initialization and setup BSS operation. However, a call trace has been
observed where a BSS link item is not present in the list and an attempt
is made to delete it from the list. This scenario occurs during the
deinitialization operation, which calls hostapd_bss_link_deinit() and
tries to remove the hapd->link which is not present in the list.
Ensures that the link item is added to the list only after the
successful operation of link addition. Also ensure that mld->num_links
increments only when the addition is successful. Therefore, return from
hostapd_bss_link_deinit(), if mld->num_links is zero. Since the mld
object is shared among all the links, num_links has to be incremented
only when the addition is successful.
Call trace:

hostapd_interface_deinit ()

When we are configuring automatic channel selection, we are not able to
switch to a given DFS channel because when we are trying to move to a
DFS channel, the interface is disabled and enabled again. When the
interface is disabled and enabled we are setting iface's freq and
channel to 0 in setup_interface2() in case ACS is enabled, and now we
don't know to which channel we were trying to move. Now ACS will run and
the interface will be up in the channel that is suitable.
To fix this issue add a flag named is_ch_switch_dfs to check if the
channel switch request is for a DFS channel and we can use this in
setup_interface2() to decide whther we have to set iface's freq and
channel to 0 or not. This way iface's freq and channel will retain the
values while channel switching to a DFS channel when ACS is enabled.

whole MLD was brought down. All other links were stopped beaconing and

stopped which is wrong.

Link ID was assigned when BSS is going through setup and the driver
interface init. Later if interface is disabled and enabled again, setup
BSS is called which will give a new link ID to it. However, Link ID
should be same for a BSS affliated to an AP MLD for the full lifetime of
the BSS.
Hence, assign the link ID during BSS creation itself. And it will remain
until BSS entry is completely freed. Hence, link ID will not change as
part of disable/enable.
Also, since link ID would be decided now, it will help in creating link
level control sockets in a subsequent patch.

MLD level information like MLD MAC address, next link ID, etc. was
stored in each BSS. However, only the first link BSS assigns values to
these members and the other link BSSs store references to the first BSS.
However, if the first BSS is disabled, the first BSS reference in all
BSS should be updated which is an overhead. Also, this does not seem to
scale.
Instead, a separate MLD level structure can be maintained which can
store all this ML related information. All affiliated link BSSs can keep
reference to this MLD structure.
This commit adds that MLD level structure. However, assigning values to
it and using that instead of BSS level members will be done in
subsequent commits.

mld_id was provided as a user configuration to identify partner BSS
belonging to the same AP MLD. The same id is used at the protocol level
also to indicate the AP MLD ID of the MLD.
But, in general mld_id is a relative reference of the MLD where 0 is
used as the mld_id to represent the self MLD and in case of MLO MBSSID
mld_id of a non transmitted BSS affiliated to an AP MLD is based on the
relative BSS index of the non transmitted BSS from the transmitted BSS.
Hence mld_id need not be fetched from users, rather it can be identified
wherever required.
To verify if the partners belong to the same AP MLD the interface name
can be checked, since all link BSS partners of the same AP MLD belong to
the same interface.
Hence, remove use of mld_id user config and instead introduce two
functions hostapd_is_ml_partner() and hostapd_get_mld_id(). The former
is used to verify whether partners belong to the same AP MLD and the
latter is used to get the MLD ID of the BSS.

The CHAN_SWITCH command handler iterates over all configured BSSs and

hostapd reads the list of Rx Key Holders from hostapd.conf file.
However, for systems where topology changes dynamically, the update
of RxKHs list is required without reloading the whole configuration.
Introduce a new source of RxKH definition with original syntax:
- rxkh_file - Path to a file containing a list of RxKHs.
In addition, add a control interface command RELOAD_RXKHS to
reload RxKHs definition from the file specified in `rxkh_file`.
This allows hostapd to properly distribute Rx keys even after topology
change (assuming rxkh_file is updated and reload_rxkhs command issued).
Syntax of rxkh_file is the same as extraction of r0kh and r1kh options
from original hostapd.conf file.
