freebsd kernel with SKQ
cf9be7c92a
This is a pretty good reference for teaching an almost-11n-capable driver about 11n. It enables HT20 operation, A-MPDU/A-MSDU RX, but no aggregate support for transmit. That'll come later. This means that receive throughput should be higher, but transmit throughput won't have changed much. * Disable bgscan - for now, bgscan will interfere with AMPDU TX/RX, so until we correctly handle it in software driven scans, disable. * Add null 11n methods for channel width / ampdu_enable. the firmware can apparently handle ampdu tx (and hopefully block-ack handling and retransmission) so I'll go review the linux code and figure it out. * Set the number of tx/rx streams. I /hope/ that nchains == nstreams here. * Add 11n channels in the call to ieee80211_init_channels(). * Don't enable HT40 for now - I'll have to verify the channel set command and tidy it up a bit first. * Teach the RX path about M_AMPDU for 11n nodes. Kinda wonder why we aren't just doing this in net80211 already, this is the fourth driver I've had to do this to. * Teach rate2ridx() about MCS rates and what hardware rates to use. * Teach the urtwn_tx_data() routine about MCS/11ng transmission. It doesn't know about short-gi and 40MHz modes yet; that'll come later. * For 8192CU firmware, teach the rate table code about MCS rates. * Ensure that the fixed rate transmit sets the right transmit flag so the firmware obeys the driver transmit path. * Set the default transmit rate to MCS4 if no rate control is available. * Add HT protection (RTS-CTS exchange) support. * Add appropriate XXX TODO entries. TODO: * 40MHz, short-gi, etc - channel tuning, TX, RX; * teach urtwn_tx_raw() about (more) 11n stuff; * A-MPDU TX would be nice! Thanks to Andriy (avos@) for reviewing the code and testing it on IRC. Tested: * RTL8188EU - STA (me) * RTL8192CU - STA (me) * RTL8188EU - hostap (avos) * RTL8192CU - STA (avos) Reviewed by: avos |

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. See build(7) and 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. See build(7), config(8), and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html for more information. 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 kernel configuration files reside in the sys/<arch>/conf sub-directory. GENERIC is the default configuration used in release builds. NOTES contains entries and documentation for all possible devices, not just those commonly used.
