[BPI-R4] bad switch performance in upload

my problem that i reported is fixed:

dangowrt mentioned that some link partners might have problems, but i assume its something different then what i reported because i had problems on client side. guillo seems to have problems on all lan ports after using that 100mbit device?

Yes when a 100Mbits device is connected all the ports are limit to 100Mbits in upload (device to router)

@frank-w i’m on the latest snapshot

That would be bad and should probably be considered a bug. If you have one 100 Mbit device plugged into the switch, you’d normally expect other devices to still run a 1Gbit if they are capable.

who all have this issue can you please show ethtool like @oli did for the port having a 1G client while having 100M client on another port? just to nail this a bit down (advertisement issue should be fixed, but maybe it is another one)

@oli can you do 1G bidirectional traffic to the rpi5?

i dont know how, the rpi5 is running libreelec and i have no idea if they have an iper3 package. any idea how to verify that?

You can use also another device,just to make sure you can have ~940mbit/s bidirectional while havin the 100m device connected

i will see if i can plug in the laptop tomorrow. i have no other device - all are connected by wifi, only the rpi5 is connected with a cable.

Hello,

This is the data when 100M device is connected (on lan2):

If you need something else you can ask me.

Looks like it is a tx issue from client pov (dsa receive,tx to mac)

So it is not the same bug as before ?

i have indeed the same problem:
