Linux ath9k doesn't have this issue as it doesn't try queuing multi- descriptor frames to the hardware. Before, I was only setting the first and last descriptor in the final frame correctly - and that was done by accident. The first descriptor in the last sub-frame was being correctly updated by ath_tx_setds_11n(); the last descriptor in the last sub-frame was being correctly updated by ath_buf_set_rate(). But both of those are "incorrect". The correct behaviour is: * AR_IsAggr is set for all descriptors for all subframes in an aggregate. * AR_MoreAggr is set for all descriptors for all non-final sub-frames in an aggregate. Ie, all descriptors in the last sub-frame of an aggregate must have this field set to 0. I still need to do a couple of extra passes to ensure the pad delimiter field is being correctly handled in all descriptors in the last sub-frame.
This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel, the kernel-modules and the contents of /etc. The ``world'' target should only be used in cases where the source tree has not changed from the currently running version. See: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables. The ``buildkernel'' and ``installkernel'' targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html And in the config(8) man page. Note: If you want to build and install the kernel with the ``buildkernel'' and ``installkernel'' targets, you might need to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/<arch>/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
