Christian Lamparter f3ffac90bc ath79: gmac: add parsers for rxd(v)- and tx(d|en)-delay for AR9344
Some AR9344 boards do very poorly with the default settings and
need custom rxdv-delay, rxd-delay, txd-delay, txen-delay flags
to perform reasonably.

In this case the WD My Net Wi-Fi Range Extender can not even
manage 10Mbps on a 1Gbit link:

root@AR9344:~# iperf3 -s
-----------------------------------------------------------
Server listening on 5201
-----------------------------------------------------------
Accepted connection from client [...]
[  5] local [...] connected to client
[ ID] Interval           Transfer     Bitrate
[  5]   0.00-1.00   sec  1.09 MBytes  9.16 Mbits/sec
[  5]   1.00-2.00   sec   895 KBytes  7.33 Mbits/sec
[  5]   2.00-3.00   sec   762 KBytes  6.25 Mbits/sec
[...]
[  5]  10.00-10.03  sec  17.0 KBytes  4.74 Mbits/sec
- - - - - - - - - - - - - - - - - - - - - - - - -
[ ID] Interval           Transfer     Bitrate
[  5]   0.00-10.03  sec  9.00 MBytes  7.52 Mbits/sec

with but with the correct settings in place, it does much better:

root@AR9344:~# iperf3 -s
-----------------------------------------------------------
Server listening on 5201
-----------------------------------------------------------
Accepted connection from client [...]
[  5] local [...] connected to client
[ ID] Interval           Transfer     Bitrate
[  5]   0.00-1.00   sec  23.1 MBytes   193 Mbits/sec
[  5]   1.00-2.00   sec  23.1 MBytes   194 Mbits/sec
[  5]   2.00-3.00   sec  23.2 MBytes   195 Mbits/sec
[...]
[  5]  10.00-10.04  sec   710 KBytes   180 Mbits/sec
- - - - - - - - - - - - - - - - - - - - - - - - -
[ ID] Interval           Transfer     Bitrate
[  5]   0.00-10.04  sec   237 MBytes   198 Mbits/sec

The tx data and enable delay bits definitions are taken from Atheros'
AR9344 Data Sheet Section "8.6.1 Ethernet Configuration (ETH_CFG)" on
page 153.

 -----------------------------------------------------

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.
