When a scan request is received, driver selects a link id for which the arvif can be mapped. Same link is also used for getting the link conf address. Currently, we return 0 as link id for a non ML vif, which is correct since that is the default link id. Also when any of the link vif is active and the scan request is for a channel in the active link we return its link id. But, when we don't hit both of the above cases (i.e not a ML vif or no active link vif for the channel is present) we currently return 0 as the link id. Bu the problemis that this might not work out always, eg., when only one link (eg. linkid = 1) is added to vif, then we won't find any link conf for link id 0 in the vif resulting in scan failure. During AP bringup, such scan failure causes bringup issues. Hence avoid sending link id 0 as default. Rather use a default link for scan and default link address for the same. This scan vdev will either be deleted if another scan is requested on same vif or when AP is broughtup on same link or during interface cleanup.

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.
