The following modules have been disabled for either being broken,

* mscs
* nssinfo (netlink + libnl-nss)
`is_mlo_device` is a check for whether a device is multi-link operation
capable, it is also geared towards WiFi 7 which is only supported on
IPQ95xx/53xx platforms with SFE. Since these patches are only focused on NSS,
rather than unecessarily patching the kernel, don't check if device is MLO capable.
There are significant changes between NSS version 11.4.0.5 and 12.1 (12.0.5),
that it doesn't really make sense to use it with older firmware (i.e. using mesh releated
features).
This change will explicitly link building the proper driver and client
packages when FW 12.1 or 11.4 is selected, while also backporting
patches from 12.4.

There is an issue with NSS firmware version 12.0/12.1 where NSS WIFI
mesh feature fails to bring up meshmgr.

The only version currently working is version 11.4. It is not
confirmed if this feature was removed in firmware > 11.4, or if the
issue if with the NSS driver package, or client package wifimgr. Looking
at the code changes between NHSS.QSDK.11.4 and 12.0.5 little was changed in
nss-drv/nss-clients related to the way mesh interfaces are brought up
(dynamic interfaces), much of the changes are related to stats.
To work around the issue, allow user selectable option to choose a
specific NSS firmware. The dependency is currently not enforced when
selecting NSS mesh offloading in ath11k. Users will need to switch
manually or disable the option altogether.
