How to retrieve PHY status, counter up/down to debug network issue
Hi all,
Currently, I have an issue of network controller eth0 that suddenly becomes non-responsive, cannot ping, no UDP/TCP. It
disappears from network.
Our product is running on QNX(6.4). At the power up, after proper configuring stage, our product is sending UDP
broadcasting packages to the network. Everything is fine. I saw UDP/TCP on the
wireshark trace and I can ping the system within the network. Suddenly, it disappears from network. I cannot
ping it, no more UDP/TCP showing on the wireshark. Instead remote machines sends ARP to the network. It can be fixed
just be pull out the Ethernet cable and plug back in. I don't know what is causing it. it seems the network driver goes
to some weird state.
I would like to debug deeper on the network stack. How should I get the PHY status, counter up/down, etc?
Hope I can get some help from this site.
Thanks in advance..
