nice to see an article from my industry! st2110 is such a complex standard which a lot of the hardware mentioned has been molded to deal with.

Most 2110 kit relies on narrow timing. That means packets arriving and leaving in a window on the order of 10 microseconds. Doing that in software reliably for your typical 100gbit interface is challenging.
Challenging but certainly doable with kernel bypass technologies and dedicated CPU cores.
It generally also needs help from the NIC, to pace out the packets at the right timestamps. (Typically delivered as part of said bypass technologies.)
