[coreboot] Quality network interfaces?

This is kind of off topic but I don't know of any other ML with such a 
level of hardware knowledge.

I am looking for dual port gigabit and 10 gigabit PCI-e NIC's that 
aren't made by intel but don't require silly binary drivers or what not 
(ie: the closest thing to free) What would be my best option?

I know raptor/tim uses broadcom netxtreme's on the TALOS 2, has anyone 
gotten a pci-e card version of these? and if so do they work well? (ie: 
high performance, low interrupts, at least 100MB/s)

I don't want to support futher intel anti-feature development and I am 
tired of ending up stuck with counterfeit intel NIC's which have even 
made it in to the non-grey market supply chain.
