In the current minimum chandef code there's an issue in that the recalculation can happen after rate control is initialized for a station that has a wider bandwidth than the current chanctx, and then rate control can immediately start using those higher rates which could cause problems. Observe that first of all that this problem is because we don't take non-associated and non-uploaded stations into account. The restriction to non-associated is quite pointless and is one of the causes for the problem described above, since the rate init will happen before the station is set to associated; no frames could actually be sent until associated, but the rate table can already contain higher rates and that might cause problems. Also, rejecting non-uploaded stations is wrong, since the rate control can select higher rates for those as well. Secondly, it's then necessary to recalculate the minimal config before initializing rate control, so that when rate control is initialized, the higher rates are already available. This can be done easily by adding the necessary function call in rate init. Change-Id: Ib9bc02d34797078db55459d196993f39dcd43070 Signed-off-by: Johannes Berg <johannes.berg@intel.com> |

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.
