Currently, ieee80211_ie_build_he_oper() lacks support for 320 MHz handling (already noted as a TODO). This is because 320 MHz is not included in IEEE 802.11-ax. However, IEEE 802.11-be introduces 320 MHz support and if the chandef indicates a 320 MHz bandwidth and is used directly as it is, it will result in an incorrect HE Operation Information Element. In order to support EHT 320 MHz, HE Operation Element should indicate bandwidth as 160 MHz only. In EHT Operation IE, the correct bandwidth will be present. Devices capable of EHT can parse EHT Information Element and connect in 320 MHz and other HE capable devices can parse HE and can connect in 160 MHz. Add support to downgrade the bandwidth in ieee80211_ie_build_he_oper() during 320 MHz operation and advertise it.

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.
