I have seen similar problems on a different board with QCA9557+QCA8334 on RGMII interface but I was able to solve it with correct pll_1000 values on SoC side and {tx,rx}clk_delay{sel,en} on switch side (but that maybe just bypassed the real issue).

I suppose that the problem could be also related with the fact that QCA8334 has the same id as QCA8337 and that workaround should be applied only for QCA8337.

nbd:

I think this is probably not related to QCA8334 vs QCA8337. I believe the issue is the fact that the rx delay setting needs to be in sync between the switch core and the SoC ethernet MAC. Which means we need to update all boards that use QCA8337 or similar.

we can confirm this.
a bisect led us to the same commit.

older versions of the board (~ s/n 1041xxxxx) don't seem to be affected.

eripek:

Same observation here:
4x TP-LINK TL-WR1043v2
1x TP-LINK TL-WDR3600
They are all QCA 8327, not 8334.

The TP-Links are all running LEDE 17.01.4 in a VLAN only setup. They are all connected with their blue WAN-Port, which is configured as a trunk port, to a Gigabit Ethernet Switch (various manufacturers)

Running iperf -c against a machine running Linux - 125-200 Mbit/s.
Running iperf -s / iperf -c between machines running Linux over three of the VLAN-aware Switches results in > 950 Mbit/s.
Running iperf between to 1043NDv2 connected by one the VLAN-aware switches results in in 90-166 Mbit/s. The same happens in between any of the TP-Link TL-W*s.
It seems to be the bottleneck for WLAN (Multi-SSID/VAP only) as well. All WLANs are limited to around 20-30 Mbit/s.

func0der:

I am having a similiar issue with the Archer C2600 which also has the QCA8337 switch build in.

I have no problem getting high speeds over the LAN ports, but if the packages have to travel from the LAN to the WAN port, they come almost to a hold.

I had a wild flashing series just a couple of days ago and it seemed to work for a couple of days after I flashed from 17.10 to 18.06-rc1 and I enabled HW NAT.
I think that was just a coincidence though.

The problem first occurred with 17.10, I think. I had it running for a long time with no problems. Again, I think, that I was just lucky there, because the problems occurred at initial setup and then disappeared.
Then after upgrading to 18.06-rc1, because of the annoying rebooting bug in the C2600 firmware, it happened.

I thought that a memory is running full somewhere, because it takes some time for the problem to show up. Also I would suspect those memories to get wiped on upgrades.

Any ideas?

I can provided logs and stuff, if I know which one you need.

eugeneai:

Hi!

I have similar issue on NETGEAR WNDR3800.
I've tired 18.06.1, 17.01.6 and checked/unchecked option "Enable learning and aging", the issue existed.

Then returned to 15.05.1.
With "Enable learning and aging" turned off the data flow is stable at 97 Mbps (router<->workstation and workstation<->workstation).
With "Enable learning and aging" turned on the speed raises (800Mbps for workstation<->workstation and 120Mbps router<->workstation)

It seems 15.05.1 works well.
How to port setup from 15.05.1 to 18 branch?

My switch is "rtl8366s" (RTL8366S). 17 and 18 notify, that it is not fully supported.

Best regards,
Evgeny

I have this problem as well with 18.06.1 on a TP-Link TL-WR1043N V5. This is a popular router and is even advertised for use with OpenWRT; any chance this bug could get some love?
