we actually need to test this on a qca8327 switch... it looks like any ipq8064 is qca8337
My RB2011UiAS has an 8327 but connected to an AR9344 which is not DSA enabled as of yet. However, this is on my todo-list (;-p).
Yeah, looks like the QCA8327 is rather rare. Wikidevi only lists one single device the Compex WPJ428 but it's an IPQ4028 based one:
https://wikidevi.wi-cat.ru/Compex_WPJ428
OK, I guess it used to be called AR8327 but that one I can also not spot in any IPQ8064 design...
@Ansuel I am compiling a new image now for my C2600. However, looking at deviwiki, the C2600 also has a qca8337. Are you still interested in the data?
UPDATE: Regardless, here is the logread and the kernel log from an Archer C2600: https://1drv.ms/u/s!AlHg8pmWgJJ_gr53Rv8mWyEn4AL4Tg?e=A89xyn
I built against latest master branch, and I applied in order all 17 x of your patches.
Can someone use the router for some days and check for any problem?
That will be harder for me at the moment since wife and I both are currently working from home, stability more than anything is needed at the moment. I can leave it booted for a few days, no problem, but will be basically idle. I could run some iperf tests across the switch if that will help. Maybe others have the ability to use as primary for the time being?
At least according to wikidevi (which isn't necessarily accurate and including devices not supported by OpenWrt), I haven't found any ipq8064 devices with QCA8327 so far - only QCA8337/ QCA8337N or single/ dual-phy switches like QCA8075.
well that's good to know
And you checked for AR8327 as well as that's what that 10 year old device is mostly still referred to?
I checked all 25 ipq8064 devices known to wikidevi.wi-cat.ru and en.techinfodepot.shoutwiki.com individually, sometimes going back to the FCC images where there was no clear listing in the switch information.

anyway i notice some device doesn't use the switch config at all and are directly connected to eth0 and eth1 strange
I have just flashed my main router (another Tp-link VR2600) with your firmware, so far so good. I'll keep you updated

ok i've started experimenting to see if I can actually get dsa to work
while making changes to the config I got this one

[ 33.106325] Rebooting in 3 seconds..
maybe swconfig is trying to do something it shouldn't since only dsa should be getting used
looks like you still have the old binding in the dts
ok i'm trying a full merge of your branch and i've edited qcom-ipq8064-eax500.dtsi
to reflect the same as you did here:
make sure you commented the old mdio node
i should be good to build without the swconfig package yes ?
yes swconfig should not be compiled
ok it has booted up OK
i'll see if I can get anything working now
https://ghostbin.com/paste/G9ggd
basic config seems ok
i'm not sure exactly how to go about vlan configuration
