Currently for single radio devices (ah->num_radio == 1) ath12k_mac_op_add_interface() creates vdev and later hw scan and assign_vif_chanctx uses the same. For MLO, vdev create request should carry ML address which will not be known during ath12k_mac_op_add_interface() as vif will be marked as ML only after links are added to it. If hw scan is requested, the vdev will be deleted post hw scan and subsequent assign_vif_chanctx call will create new vdev with ML address. But in certain cases assign_vif_chanctx could be called without any prior hw scan request and reusing the previously created vdev causes a non-ML vdev to be used for an ML vif and firmware operates the vdev in non-ML mode. Fix this by deferring vdev creation for interface until hw scan or assign_vif_chanctx request is received from mac80211.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
