The 10G network can send data but cannot receive data

muaxi8 — Tue, 12 Oct 2021 06:34:07 GMT

The network can send data but cannot receive data.

we used the marvell 88x3310 phy device. I have checked the PHY checklist and there is no problem. The PHY drivers have been loaded successfully.

Usxgmii is used for THE PHY and DPMAC14, and 10GBase-T mode is used for the outside of the PHY.Currently, ping the target device under the kernel, the target device can receive data, and also responded, but our LX2160 can not receive data

Can you give me some debugging advice?

Please run icmp ping for a while and then stop it.

Then share us the output of following commands -

restool dpmac info dpmac.14

restool dpni info dpni.1

Also give us the full boot logs, right from u-boot to linux shell

Re: The 10G network can send data but cannot receive data

yipingwang — Wed, 20 Oct 2021 05:25:27 GMT

Are you using generic PHY driver or specific PHY driver say - drivers/net/phy/marvell10g.c ?

In case you are using specific PHY driver, then Can you use generic driver once and see if your problem still persists.

generic PHY driver and specific PHY driver ---- drivers/net/phy/marvell10g.c

I've tested them all, are the same prolem.

the problem is resolved.it is a hardware problem

@yipingwang I am trapped with this bus for a long time,could you help me ?
dpmac increase with rx frags when host pinging 2160, but dpni could not get data from dpmac.17
