Info re i350-T4 (Fake vs Real)
FYI Those cheap Chinese i350-T4/AM4 nics on ebay work!

Info about Quanta LB4M (Far from cheap rubbish):

Cheap (known good) 10gbit cards:
Cheap 10Gb SFP+ $19 Mellanox ConnectX-2 EN Cards
Chelsio dual port 10g NIC $19.72 with free shipping
The chances of getting a "fake" vs a real i350 are high, which is why I recommend NOT going for one, vs a 10 gig nic (which will have SR-IOV) which is unlikely to be a fake.
Further, 10gigabit Nics have a purpose in mixed networks, where you need >1gigabit and don't want to break the bank. Much cheaper to manage a single cable run also vs multiple for trunking. I personally have 10gigabit (chelsio t420) feeding 6x1 gigabit links, it is never overloaded. It also runs sriov, multiple vlans and other stuff quite happily. For reference I run a Mikrotik CRS226 (which is a 24x1 gigabit and 2x10gig switch- my desktop and server are on 10gigabit, all the other clients are on 1gigabit)
There are very very few things you would that favour a 4 port 1gig card over a single 10gigabit card if both are options
This is my final reply to you gig-e-nator - If you don't like my answer, please don't reply specifically to me, I really don't appreciate your tone.
