So, what made you thinking that the enp0s3f0, enp0s3f1 and enp0s3f2
interfaces weren't working? I failed to find any immediate problem in
the log.

I'm sorry. I made a mistake. It works fine.

The driver registered eight Rx-queues (and likely eight Tx-queues).
enp0s3f0 and enp0s3f2 links got up. Even the log reported that two
interfaces have some network access (whatever it meant in your
boot-script):

The device(7a03 and 7a13) can access the network.

Yes, there is only one IRQ registered for each interface. But that's
what was expected seeing you have a single MAC IRQ detected. The
main question is: do the network traffic still get to flow in this
case? Are you able to send/receive data over all the DMA-channels?

Yes, I can. in this case, enp0s3f0/1/2 can access www.sing.com.


Because I did another test. I turn on the checksum.

In this case, enp0s3f0/1/2 cannot access the www.sing.com.

therefore, the network traffic still get to flow, and I can

send/receive data over all the DMA-channels.

If there are any other tests you would like me to do, please let

me know and I will be happy to do them.

Thanks,
