In kernel 4.4 cpu-port is also set to trgmii
Maybe something like this is missing: http://lkml.iu.edu/hypermail/linux/kernel/1609.2/04008.html or https://patchwork.kernel.org/patch/9341133/
Or only 1port support trgmii…this schould be lan-port…so i guess we have to swap cpu-ports
@garywang @linkerosa can you bring light in the dark?
Yeah, the kernel is LEDE kernel with several small patches on top to fix BPI-R2 in several places (see https://github.com/abbradar/openwrt/tree/bpi-upstream/target/linux/mediatek/patches-4.14 , 0228 and onward).
On LEDE 4.9, Banana Pi’s fork, both ports are set to trgmii so this shouldn’t be the problem…
does your patch really fix the damaged packets-issue on cpu-port0 (lan)? then it seems that trgmii is handled wrong by code (headerbytes stripped again or similar)
The packets seemed to be trimmed in Wireshark (also checksums were reported as invalid but this is because of trimmed content I believe).
I have the board now working with both lan*@eth0 and wan@eth1 used. Packets are not corrupted.
ok, i will try it…but trgmii-driver should also be ok because actual dts (here from my 4.14-main) without 2nd gmac is working with trgmii
gmac0: mac@0 {
compatible = "mediatek,eth-mac";
reg = <0>;
phy-mode = "trgmii";
fixed-link {
speed = <1000>;
full-duplex;
pause;
};
};
…
port@6 {
reg = <6>;
label = "cpu";
ethernet = <&gmac0>;
phy-mode = "trgmii";
fixed-link {
speed = <1000>;
full-duplex;
};
};
btw. have you seen my tests:
17:13:42.430047 IP truncated-ip - 6 bytes missing! 192.168.0.10 > 192.168.0.5: ICMP echo request, id 815, seq 9, length 64
tcpdump from my other router…means outgoing packets are damaged not (only) incoming
Interesting… This seems something complex – my patch definitely helped me and I can’t run more tests now but I’ll maybe try switching trgmii on and off on both ports later and see what happens.
FWIW I also have some funkiness regarding speed negotiation (with a host which works with other router) but it doesn’t seem to be related at the first glance.
Yes, you are right – I meant incoming to the other host which I tested this on. Packets incoming on R2 seemed well.
I have some news – I’ve tried to enable TRGMII on both ports instead and voila, it still works! I’ll take some time to verify that current kernel image has the modified DTB – just in case.
i can confirm, that cpu-port0 works with this patch (changing trgmii to rgmii)
you mean the problem may be that the other port was not in trgmii-mode?
Yeah, seems so. I’ve pushed an updated patch to my branch.
can confirm it works with wan and lan0, but currently not with lan1,2,3
i get dhcp-reply (ip set by my router), but i cannot ping it…strange
ignore it…dhcp sets same address to all tested interfaces, so i have to manually shut down the prior ports not only move cable
in my gmac-branch there is a file mt7623a-rfb-emmc.dts created by any of the patches…is that really necessary? can’t compile without it, but found nowhere it is referenced (not in mt7623.dtsi and not in bananapi-r2.dts). do you have this in your tree?

I will try to comment-out in makefile when i’m at home…
works also without reference-board
see last commit in gmac-branch: https://github.com/frank-w/BPI-R2-4.14/commits/gmac
@abbradar can you push the changes to official lede and mainline?
@pkalemba now you can try hnat on top of this
created a single patch for 4.14: gmac.diff (23,6 KB) (based on 4.14.19)
created a new branch from actual 4.14 (4.14.52) and applied patch to it.
works well in my short test

note that you have to set eth1 to up before you get wan-port up
in /etc/network/interfaces:
auto eth0
iface eth0 inet manual
pre-up ip link set $IFACE up
post-down ip link set $IFACE down
auto eth1
iface eth1 inet manual
pre-up ip link set $IFACE up
post-down ip link set $IFACE down
i can ping my router over all ports (only 1 have to be in that subnet! the others I have set to down)
anyone else tested it?

I’ve already merged 2nd gmac to 4.14 main because it looks stable now
That’s already from 4.14-main and debian stretch
