When we have an AP which supports HT and a single HT station is connected, we change the min_width from NL80211_CHAN_WIDTH_20_NOHT to NL80211_CHAN_WIDTH_20. This of course has no implication on the channel width but still sends a command to the firmware. Remember the last width that was sent and refrain from sending unnecessary commands to the firmware. Sending a PHY_CTXT_CMD to the firmware has a cost since it recalculates the presence on the medium and because of that it closes the transmit queues for a short while.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
