yes i noticed that part was missing, but the card i have is an I350-T2 andaccording 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'lldouble check what is listed on the card itself.
Some OEM's (ex: dell) shut off the SR-IOV ability on their NIC's because 
reasons.
Please provide an lspci -n and lspci -v -v for that device so we can see whatOEM it is.
I would return it and have them send you a real one that isn't nerfed, also FYImost NIC's on ebay are counterfeit so be careful what you buy.https://www.servethehome.com/investigating-fake-intel-i350-network-adapters/(real intel NIC ASIC and SR-IOV but crappy secondary components)


if i look at the back of the card there is a sticker with: I350T2V2

here is the output:
# lspci -s 03:00 -n
03:00.0 0200: 8086:1521 (rev 01)
03:00.1 0200: 8086:1521 (rev 01)

and the long one:
# lspci -s 03:00 -v -v
