I think the issue, unlike with Dante and AES67, is that 2110-20 uncompressed video has pretty onerous requirements for timing and throughput - such that normal SFP+ NICs on PCI-E cards require more than just software at the user level to work with 2110-20/-30 etc. (For the same reason you can't use regular switches either)
The BBC has done some work with Mellanox and Netmap on bypassing the kernel to improve throughput - but the reason most 2110 capture/generation solutions for COTS hardware have integrated NICs (and aren't just virtual devices with software drivers) is that generic NICs and OS level support for them isn't good enough for 2110 on its own - or so I understand?
