[dpdk-users] Port binding issues : NIC intel 82599ES

[dpdk-users] Port binding issues : NIC intel 82599ES

[Shyam Shrivastav]

Hi
I just started on dpdk, was trying to run l2fw. I bind two 82599 ports
using dpdk-devbind to igb_uio (first tried uio_pci_generic with same
result), then run l2fw but EAL is unable to probe these drivers still
getting ixgbe. Here is the console output

[root@unassigned build]# dpdk-devbind --status

Thanks, Yes indeed we need to go through documentation, my case I was in
hurry passing through commands to get into real action so missed the dpdk
specific "--" separating EAL and app specific options. I realized my
mistake soon afterwards while looking at app code, updated the thread on
web list archive, probably another mistake !
I am moving well with my project using dpdk  for now ...

Hi Shyam,

In your case try the following:
./l2fwd -c f -n 2 -- -p 0x3 where -p 0x3  indicates that you want to use port 0  and  port 1 with the l2fwd app.

For future experiments you'll need read through the dpdk documentation so you can gain better understanding.

Regards,

Hristo
