So trying to fix the above crash I made two changes to the patches. In the vanilla backport I increased the TX timeout to 40 * HZ where it was 30 and probably OpenWrt uses 10. Next in the dma descriptors patch there was a comment that there were 192 descriptors per channel but the hex value was 0x80 which meant it was 128 and not 192 so I changed it to C0 and after compiling and flashing the TX side from the router seems to be stable for about 20 seconds at full speed and then it crashes. While before at least for me it wouldn't last 3 seconds.
On the other hand, something seems broken in the tx_housekeeping function because most of the time the crash happens in this but sometimes it also happens with napicomplete function. I am not sure if the last function name is correct but anyway I wanted to understand how it was working and how I could improve it.
One last thing that I want to know is there any way I can load these changes without flashing the firmware to the flash? I know there is a initramfs image available in the config and it's around same size as sysupgrade but how do I use it? I have serial access of course but I personally think that too much flashing may deteriorate the flash chip on my HH5A. Any thoughts?
FYI I re-flashed my HH5a ~100 times with snapshots and do not see any issues with nand yet.

I understand but I think it's better to use initramfs image for bricking issues. For instance while making changes above I wasn't able to use the lan ports for a little while and even static IP was not working. Then I connected it with my main wifi through WDS and transferred the image. After all I will have to flash it pnce the patch is stable enough.

Gonna go for these patches tomorrow. Just play with wifi for now.

OK a new set, including IRQ balancing. There are debug leftovers and dead code, but it should work. I did the whole wave300 wifi development with this ethernet driver version. The IRQ balancing is 2 days old, but it seems to work (better than my previous version). I didn't test the both patchsets separated (as it don't have reason to have slow ethernet on 2 VPEs), altought I did test the updated ethernet driver on a single VPE (nosmp kernel parameter). If you want to test it yourself, it should be possible just by splitting the patchsets into 901-903 and 904-906.
BTW All older patches from me are obsolete by this. The patchset is for (older) kernel 4.14.99. Apply them by copying into target/linux/lantiq/patches-4.14 and by recompiling the kernel.
If you got some kernel warnings/oopses, please send the debug log (IRQ has this thread , but I guess it doesn't matter that much).
I didn't test the compatibility of IRQ driver with those devices, which requires one VPE to be disabled (and later some proprietary driver runs on it). If you have these, PLEASE test. Same it seems (from device-tree) the IRQ driver is used by Danube, AR9, AmazonSE and Falcon devices. These won't work with patched device-tree for IRQ patchset (you can test them by changing the "reg" field accordingly) or contact me (I don't know about its hardware specs).
The benchmark is in the tarball. But it seems the ethernet is over 350 Mbps (host to xrx200) and over 260 Mbps (xrx200 to host) (iperf3, TCP traffic). The vanilla kernel has only 178/81 Mbps.
P.S. I didn't use the irqbalancer before (it would bring a nondeterminism into the debug setup), but it seems it may not even work o_O. So I've changed the IRQ driver to autobalance IRQ itself (the code is actually cleaner

Well I was gong to post some exceptions related to last patches because there were errors in the tx_housekeeping function related to napi_complete_done and also in rx_poll function. Well rx_poll function would randomly crash at boot sometimes although there were no errors in transferring data. But with these new patches, time for more tests. Will report back later.
Edit: I ran some tests using iperf3 and also ran your script. Although your log says otherwise I am getting some packet loss around 20% when transferring from Router -> Client. On the other side, Client -> Router seems okay with only 0.5% packet loss at times.

I am not sure if my Laptop port is faulty because I tried two different wires. As my laptop only has one 100M port, I am not able to test more but I used one 100M cabe (4 wires) and 1G cable (8 wires) with same results as above. If there are any more tests I am happy to help.

I also ran some tests on WiFi and I am actually really happy with the overall performance on 2.4GHz but I have some concerns because while downloading data the speed kind of gets dropped very low and then goes up and keeps repeating this behavior. Is it because of CPU limit?
This behavior is also observable from iperf but I also copied a file from HDD to my Laptop and I was able to get around 11mb/s but it would drop to around 1mb/s after a few seconds and then would go back up. Also the packet loss?

Edit: I would like to say that IRQ balance is actually really good and it balances everything just perfectly between the two cores. I think with above tests and file transfers that I made, there may be still room to optimize it further but of course I dont really know for sure since I am not a C programmer myself but just saying this because there seems to be bugs and if they get sorted out maybe the performance will improve further. Btw I have transferred 78 GBs of data from my Laptop to W8980 using Samba, it took around 5-6 hours because of 100M port but I think WiFi is faster than 100M port if you force 40mhz because I was able to get 12mb/s on Wifi but only 9mb/s on ethernet.

In my notebook the wifi is fluctuating too. You would have to make the perfect setup (no channel contention - almost impossible on 2.4GHz 11n), station next to AP, no power management on both devices (they will go into standby if no continual transmission - symptom: laggy ssh).
Well that doesn't have to mean balancing 1:1 will get you the best speed. You would need to account userspace SMP affinity and time how long it gets to handle one individual interrupt source.
You should try to restrict the interrupts in smp affinity to a single core and try to run the benchmarks again (wifi and ethernet).

Tested on 4.14.105 kernel. Weird, it seems there is about 10Mbps TCP drop in lantiq RX, 4.14.99 was better. And it is only in the kernel, I've tested on the same userspace and both without modules. But it is still faster than vanilla

I tested wifi on different affinity settings, 1,2,3 etc. It turns out download is completely fine from router -> client more than 99% in my guess. But there is problem in uploading from client -> router. It shows packet loss on every transmission. Although it's minimal but I think it's one of the reasons why the speed fluctuates while uploading, it's possible there are bugs?
Yes it's faster, that's for sure (Thanks to you). I get around 110mbps on download on wifi and around 60-70mbps on uploading. I did not test the ethernet yet but it wont be much different.

What is the latest OpenWrt build that your are running on your xrx200 device? I am running r9614-b61495409b on my TPLink-TDW8980 and r9630-a8cfef6c45 on my HH5A and the later is causing issues. It's possible something got changed in the kernel maybe.
Well the issue is that Client -> Router seems fine if I am using my laptop with LAN cable. As soon as I reverse it (Router -> Client) the router keeps sending data at 200mbps while the LAN on my laptop is 100mbps so the laptop doesnt receive anything at all and keeps showing errors. It seems HH5A (with r9630) doesnt seem to be checking the throughput link speed for some reason.
Now if possible I would like to either go back to the commit that you are using or maybe if you can update the patches so they work well with the kernel changes. Can these patches be submitted to OpenWrt for further development and integration within the build system? This way more people can contribute to it maybe and the fixes they provide can go a long way.
I am actually happy with the wifi performance with these patches. On a 5ghz I am connecting to at 433mbps and getting throughput rate of 166mbps/22mb/s UL/DL on my phone. On a 2.4ghz I'm connecting to at 150mbps (forcing 40mhz) and getting around 90-110mbps/10-12mb/s. I also did a test using your run.sh script between my W8980 and HH5A (both have gigabit ethernet and patches applied) with current situation as above and this is the log:

My patches were made on r9569-8f9155fe7a and git snapshots before that (r9228-a3ccac6b1d was 10Mbps on the average faster).
I don't know why it is slower, only thing I've noticed, the driver doesn't track the packet statistics anymore. The original API is marked as obsoleted so it maybe why it is not tracking. That may be partially responsible for some problems. Gonna update it, other than that I don't know what could be patched.

Hmm it seems the original statistics have a problem with overflowing (only 32bit variables). So I've changed the code for the "new" 64bit API. There was some problem with crashing, so I've disabled the locks in stat function.
Try to replace the 0904-backport-vanilla-eth-driver.patch with new version https://pastebin.com/raw/WYrJGw0e ... lots of unused code there
Another change is disabling the locks in xmit and tx housekeeping functions, it seems they are not required now (I've put them there during the buggy frags rewrite and on old SMP irq version code). It seems to increase the ethernet speed.

Thanks for the update. The driver seems more stable than before with less transmission errors than before. But the 50mbps limit on throughput between xrx200 is still there for some reason. As a matter of fact I blame it on iperf3 because it could be a bug within iperf3. I am not able to use -b 0 with iperf3 because it gives me Segmentation fault error.
Anyway, I was able to test it and have found no issues so far and right now I think the last driver was quite good enough and we didnt need to update it anyway but glad you did and fixed any leftover-errors. In the testing I am getting as usual speeds and the speeds between the routers seems as it is. If I run a udp iperf3 test then it's capped at 50mbps and if I run a tcp test then it's around 120mbps max. It's no where near 1gbps but as I said before it could be an issue with iperf3. But throughput to client is okay and working full at 100mbps as before.

Maybe the iperf3 is miscompiled, and if the iperf3 was compiled as part of the openwrt maybe even openwrt is miscompiled. Try to run gdb on iperf3 it should show where is the problem (on my git snapshot there was no problem with -b 0).
I'm not sure going into much detail would yield any more benefits. The switch is working at a decent speed and I'm sure from such a lower end device asking for more would be a overkill. But anyways thanks for your help.

As an interested member of public, but not a developer, can I ask a (possibly silly) question: do you intend to merge your commits into the mainline OpenWrt code, and when is it likely to happen?

Yes I would like to, I'm just bad at making clean patches :-D.
Problem with these upgrades are they are written only from observation of the hardware behaviour and some common sense how the hardware usually works. Without documentation there may be unexpected bugs. For example I don't know why there is not full 100M in @ahmar16 case, the first implementation of IRQ SMP is fundamentally buggy (the 3.10 kernel from @paldier 's repo ). I have already contacted developers of openwrt, but usually you must be really sure what does the patch do (and there must be some measurable improvement) before it can be commited into main tree.
BTW You guys can join openwrt mailing list too and post your reviews (benchmarks before and after patching). Testing reports always helps.

Another question xD:
Are there also other non-SMP-related fix in your driver? I'm asking this because my router is more stable on LEDE which does not have SMP, so I was thinking if you could add those fixes, if any, also to LEDE drivers.
). Even with this, you can still limit the VPEs by /proc/irq/X/smp_affinity.
).
