yes very strange.
thing is, i bought it from a well known web shop I've been using forever.
i have opened a support ticket with them about this, hopefully i can return it.

but then question is, how do i find a network card with sr-iov that works?
clearly specs on web shops can't always be trusted.

also strange is that this page:
http://ark.intel.com/products/84804/Intel-Ethernet-Server-Adapter-I350-T2V2
clearly lists sr-iov and this is the model i got.
