When we remove the station, we call iwl_mvm_sta_del() which returns true if we cannot remove it from the firmware yet, which happens if this is the station ID for the AP station that's still used because the MAC is still associated. However, we still must free the link data as the station is only kept alive in the firmware, in mac80211 and driver the data structures are destroyed. To fix that, we need to make iwl_mvm_mld_free_sta_link() track whether or not the station is still alive in FW, as otherwise we might reuse the station ID in the meantime and iwl_mvm_mld_rm_sta_from_fw() would reject the later delete from the firmware. Add an argument to it for that. Then we can use the return value of iwl_mvm_sta_del() for that to fix the issue, and call iwl_mvm_mld_rm_sta_from_fw() only if we need to not keep the station in FW.

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.
