[Xenomai] Problem with rt_igb driver for I210 card

[Xenomai] Problem with rt_igb driver for I210 card

[GEORGE, Laurent]

Hi,

I have dowloaded and tested the stable version of Xenomaï 3 including a
support for the I210 (Intel) card, available at the following git:

https://git.xenomai.org/xenomai-3.git/commit/?h=next&id=8268c5e87cf0ac5223d98a86918b9420a0e94382

I have the following problem:

The Installation of Xenomai went well. When I load rt_igb.ko module, the
rteth0 interface for Intel i210 NIC goes up well but there are following 2
issues:

a) when I try the rtsolicit command to add devices in network, it doesn't
work
b) When I try to remove rt_igb module after taking down rteth0 interface it
hangs and the only way to get back is a hard restart by pressing the
restart button on PC.

I precise that I have other fully functionnal NIC interfaces based on
rt_e1000e driver on my PC.

Thank you for your help.

Best regards,
Laurent George.

"It does not work" is a bit vague. Do you wait for the link to be up
before sending the solicit? Does it return an error? Does it
send a packet but receive no answer? Some other case?

Maybe the kernel crashed and capturing the console ideally via
serial port, failing that via netconsole would help?

Some precisions on the problem:

1) I load all the required modules (like rtnet, rt_igb, etc)- No error
2) I make the rteth0 interface up - No error
3) rtifconfig -a shows rteth0 interface - No error
4) I then run ./rtroute solicit ip_address dev rteth0 - No Error
5) I then check whether the device is solicited using ./rtroute - Error (It
doesn't show that IP which I had just solicited - In normal Conditions, it
shows when there is no error)

Best regards,
Laurent.

Ok, but on the other side, do you see the ARP packet, or not? If
yes, does the other side answer or not? Do the TX and RX packet
counters increase?

Ok, but do you wait for the link to be up before sending the
ARP? Do you see RUNNING in rtifconfig ? Or do you check the link
with the SIOCGIFFLAGS ioctl?

It would be nice if you could answer all the questions you are asked
and not just a few well chosen ones.
