Keywords: RP-PPPOE, RGMII, 1 Gbps |
-------------------------------------+------------------------
Hi,
I have a router with ramips MT7620A
Buffalo WHR-1166D specifically (On current trunk)
After ruling out some of the possibilities,
I found out that
RP-PPPOE have an issue on WAN working at 1 Gbps
Here are my tests
1. 100Mbps with DHCP on wan OK
2. 100Mbps with PPPOE on wan OK
3. 1 Gbps with DHCP on wan seems OK!!!
4. 1 Gbps with PPPOE on wan NOT OK!!!
I have tried full duplex and half duplex with ethtool but in vain
I searched some posts and also tried the following
1. override setting wan mac address with
option macaddr '00:00:00:00:00:00'
NOPE!!
2. Turn PPPD warning level to debug
option pppd_options 'debug'
(Pasted Below)
3. ethtool eth0 shows the following message
Current message level: 0x000000ff (255)
drv probe link timer ifdown ifup rx_err tx_err
When WAN is on 1 Gbps with DHCP
Luci shows WAN's MAC address and TX RX packets
When WAN is on 1 Gbps with PPPOE
Luci shows NO MAC address and TX RX both 0 packets!!
(Screenshot pasted below)
The interesting fact is that it only failed with
WAN on 1 Gbps using RP-PPPOE
AND According to another post
[url]https://forum.openwrt.org/viewtopic.php?id=50648[/url]
This issue seems to be reproduced on TP-Link TL-WR1043ND v2.1
which its SoC is Qualcomm Atheros QCA9558
So, could someone verify that is it a Software Issue (RP-PPPOE)
or a Hardware Issue?
Thanks!!
MT7620A Specs:
My Buffalo WHR-1166D has ramips MT7620A
with 4 FE & 2 RGMII
1 for CPU (switch)
&
1 for WAN (on port 5)
Which its DTS file
[url]https://git.openwrt.org/?p=openwrt.git;a=blob;f=target/linux/ramips/dts/WSR-1166.dts;hb=HEAD[/url]
seems to be correct
