yes i noticed that part was missing, but the card i have is an I350-T2 and 
according to:
https://www.intel.com/content/www/us/en/support/network-and-i-o/ethernet-products/000005722.html

the I350-T2 is supposed to have sr-iov support.
i guess it is possible they sent me the wrong type of card or something, i'll 
double check what is listed on the card itself.
