In enhanced DMA ring 0 is used for RX ring, hence TX ring 0 is an unused element in ring_tx and ring2cid_tid arrays. Initialize ring2cid_tid CID to WIL6210_MAX_CID to prevent a false match of CID 0. Go over the ring_tx and ring2cid_tid from wil_get_min_tx_ring_id and on to prevent access to index 0 in eDMA.

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 Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
