Currently, dynack was only tested upstream using AP/STA mode. Testing it on IBSS, showed that late-ack detection was broken. This is caused due to dynack using Association Request/Response frames for late-ack detection, which IBSS does not use. Also allowing Authentication frames here solves this. A second issue also got fixed, which was also seen AP/STA mode: When a station was added, the estimated value would be exponentially averaged using 0 as a starting point. This means that on larger distances, the ack timeout was still not high enough before synchronizing would run out of late-ack's for estimation. Fix this by using the initial estimated value as a baseline and only start averaging in the following estimation rounds. Test setup: - 2x identical devices: RB912UAG-5HPnD + 19dB sector - IBSS - 2x2 802.11an (ar9340), HT20, long GI - RSSI's -70 / -71 - Real distance: 23910 meter Results (60s iperf runs): Fixed coverage class 54 (up to 24300m): * 21.5 Mbits/sec Dynack: * 28.9 Mbits/sec Signed-off-by: Koen Vandeputte <koen.vandeputte@ncentric.com> |

This is the buildsystem for the OpenWrt Linux distribution.
To build your own firmware you need a Linux, BSD or MacOSX system (case
sensitive filesystem required). Cygwin is unsupported because of the lack
of a case sensitive file system.
You need gcc, binutils, bzip2, flex, python, perl, make, find, grep, diff,
unzip, gawk, getopt, subversion, libz-dev and libc headers installed.
1. Run "./scripts/feeds update -a" to obtain all the latest package definitions
defined in feeds.conf / feeds.conf.default
2. Run "./scripts/feeds install -a" to install symlinks for all obtained
packages into package/feeds/
3. Run "make menuconfig" to select your preferred configuration for the
toolchain, target system & firmware packages.
4. Run "make" to build your firmware. This will download all sources, build
the cross-compile toolchain and then cross-compile the Linux kernel & all
chosen applications for your target system.
Sunshine!
