Add packet log support for QCA6390, otherwise the data connection will stall within a minute or so. Enable it via debugfs and use trace-cmd to capture the pktlogs. echo 0xffff 1 > /sys/kernel/debug/ath11k/qca6390\ hw2.0/mac0/pktlog_filter The mon status ring doesn't support interrupt so far, so host starts a timer to reap this ring. The timer handler also reaps the rxdma_err_dst_ring in case of monitor mode. As QCA6390 requires bss created ahead of starting vdev, so check vdev_start_delay for monitor mode. For QCA6390, it uses wbm_desc_rel_ring to return descriptors. It also uses rx_refill_buf_ring to fill mon buffer instead of rxdma_mon_buf_ring.

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.
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.
