Hi,

I'd like to use TRex with some 25G interfaces, and preferably use an Intel E810 card.

Is this supported / are there any restrictions or other considerations?

I see an earlier thread hitting some issues with VFs, but I'm not planning on using SR-IOV.

The documentation only acknowledges Intel XXV710 as a supported Intel 25 G card, but am guessing this could just be a little out of date ...

Thanks,
Jon

Hoi Jon,

I did not manage to get TRex to run on the 2x100G variant of Intel 810. Your mileage may vary. The VPP community has been using Mellanox ConnectX, and at least for the X5-EN card (2x100G PCIe 4.0) they run fine with TRex. 

Maybe others on the list have had more luck than I.

Is E810 software-mode only?

Hi Andrew, 
I've pushed to master this support, but regression fails
