Would this board be capable of switching AVB (IEEE 1722.1 specifically)? Existing switches are ridiculously priced, and this might be a great solution paired with some open source code for (home) music studios.
Remember for true AVB you're asking for network wide sync to the nanosecond with stream based traffic shaping and bandwidth reservations done in hardware accurate to those timings. It's all a real PITA to implement hence the price. That being said you can get a semi-reasonably priced switch like the MOTU AVB for <$500. If you need tons of ports the best way is going to be an older enterprise switch that supports AVB up for resale but beware you'll likely need the AVB license along with the hardware and it's an uncommon license.
