This works around a bootloader issue where every device
has the same lan/wan-mac 00:04:9f:ef:01:01 - with this patch
we read the macs from config-partition during initial network
setup. We have 9 valid macs stored in the partition, the
1st two are used for the radios, 3 and 4 are now used for WAN/LAN.
on an already setup / running device we can get the real macs with
. /lib/functions.sh
. /lib/functions/system.sh
echo "LAN = $(mtd_get_mac_binary config 338)"
echo "WAN = $(mtd_get_mac_binary config 344)"

from the ticket / user klondike:
U-Boot passed this commit ecd1a09b81http://u-boot.10912.n7.nabble.com/U-Boot-PATCH-mpc83xx-remove-hardcoded-network-addresses-from-config-files-td44372.html
I suppose to prevent this particular issue, but the WDR4900 may be using an old bootloader still affected.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
I have been checking the contents of the dtb on the flash, this particular bit is quite revealing:
ethernet@b0000 {
#address-cells = <0x1>;
#size-cells = <0x1>;
device_type = "network";
model = "eTSEC";
compatible = "fsl,etsec2";
fsl,num_rx_queues = <0x8>;
fsl,num_tx_queues = <0x8>;
local-mac-address = [00 00 00 00 00 00];
^^^^^^^^^^^^^^^^^
interrupt-parent = <0x2>;
phy-handle = <0x3>;
phy-connection-type = "rgmii-id";
ptimer-handle = <0x4>;
queue-group@0 {
#address-cells = <0x1>;
#size-cells = <0x1>;
reg = <0xb0000 0x1000>;
rx-bit-map = <0xff>;
tx-bit-map = <0xff>;
interrupts = <0x1d 0x2 0x1e 0x2 0x22 0x2>;
};
};
I also have been checking the live device map to find this:
root@GHS-AP3:~# hexdump -C /proc/device-tree/soc@ffe00000/ethernet@b0000/local-mac-address
00000000 00 04 9f ef 01 01 |......|
00000006
root@GHS-AP3:~# hexdump -C /proc/device-tree/soc@ffe00000/ethernet@b1000/local-mac-address
*
root@GHS-AP3:~# hexdump -C /proc/device-tree/soc@ffe00000/ethernet@b2000/local-mac-address
*
My conclussion is that U-Boot most likely finds the device and (as no valid MAC-address is provided)
falls back to the default MAC provided by the old code, the kernel then receives thee modified
device map from U-Boot and assumes this is the correct MAC for the device despite it obviously isn't.
This can be seen at
target/linux/mpc85xx/patches-3.10/140-powerpc-85xx-tl-wdr4900-v1-support.patch
The enetaddr is filled up by using the device tree data by the process_boot_dtb
function and used by the platform_fixups function to set the eth0 address
(by calling dt_fixup_mac_address_by_alias("ethernet0", enetaddr); ).
But instead we should be used the device address which to my understanding is
provided in the mtd.

replace all occurences of LINUX_VERSION with the cleaner
approach. future kernel upgrades must mostly touch only
one file. the only platform left is netlogic, because it
uses a intermediate kernel 3.14.16

ARGC is a 'C-ism', but not known/valid in shell-syntax - insert the correct
var $# (=number of args) here. under normal conditions this had no impact,
but we should at least correct it. the error was observable like this:

This is a backported patch for the gianfar ethernet driver
used in TPLink 4900 v1. It is supposed to fix the error which
show up in dmesg with:
NETDEV WATCHDOG: eth0 (fsl-gianfar): transmit queue xy timed out

The default inittab uses "askconsole" which is implemented by procd
and uses the console provided by the kernel command line.
Hence, this platform specific workaround is not necessary anymore.

This patch fixes the NAPI poll mechanism in the GIANFAR ethernet driver, which
was not properly working since Linus Kernel Version 3,8.
Therefore the workaround patch to downgrade the GIANFAR ethernet driver to
Kernelversion v3.8 is obsoete.
This patch was extensivly testes with different network loads and types of
traffic. There is quite a substantial user base that reports proper Ethernet
function with TPlink-4900. This patch is based on the fixes from GINAFAR
maintainer Claudiu Manoli.
