I'd like to start playing around with 40G, but doesn't seem to be too
many such NICs available. Does anyone have any suggestions for 40G NICs
that work well with Linux?
Thanks,
Ben

I have the situation for test 40G for Linux, which consist of 4 82599 NICs,
and I use bonding LACP mode to test the performance, when turn on the iommu for
kernel, the performance is up to 30G, when close it, the performance is up to 38G,
what do you think about it?
Thanks.
Ding

Nice performance!
But, for my purposes, I need a real 40g port to test some other 40g
equipment.
Thanks,
