Re: 25/100 G performance on freebsd

Hi,

Yes indeed these 2x25G nics are QLogic . I would like possibly to remove 10G cards though i can try the new driver. The thing is that without sr-iov I doubt i am able to have the full capcity of the card in a vm :/ .

I didn't test valve yet. I thought it wasn't fully stable. But maybe it is?
