Hello,
I have a computer I’m using for testing DPDK that has an Intel 82579LM.
Currently this NIC isn’t supported in DPDK, but I believe it is similar to others that are (such as the 82574L, which I am using successfully on another computer).
How much work would be required in getting this up and running—what functionality is missing?
I’m currently using it with AF_PACKET (and will try pcap soon), but would be interested in seeing its performance under DPDK ‘native’.
Thank you,
Omri Mor

Hi,
I wrote a little patch for you. You can apply it to the current
dpdk-master branch and test it.
My Thinkpad T430 has such a NIC and shows some rx packets and the link
status change with the patch,
when using testpmd. Maybe 82579LM was not supported for a reason, so
simply try out if it works for your purpose :)

Hi Markus,
Thanks for the patch!
I thought that it might only need the support ‘switch’ flipped on, but wasn’t sure.
It seems to work, though I get the following message when testing using `testpmd`:
EAL: Error enabling MSI-X interrupts for fd 26
I’ve also seen a couple of lost packets, which I wonder if are due to the above.
So I guess it’s missing /something/ to be entirely supported, but with this it does work (at least partially).
Thanks!
