no bodies onboard works right massively limited bandwidth and resource allocation. (too many interupts)
For example, if sending midi via ethernet from master is better than 5-pin, yet getting low latencies returning the audio from slave(s) via ASIO sound cards.
thats the old school way worked 15 yrs ago and still works just a cluster of a mess
moving into todays way
VE Pro and only 1 audio interface
but again minimum is seperate 1GB nics and a good switch.
ideal is as i said 10GBe cards (you can run direct without a switch and if you buy 1 card with dual ports then you could use 2 slaves) a swtich is around 3K+
