Is there any traffic (other than broadcast packets and TCP ACKs) going
back from the PC to the devices?  If not, it could be just that the
board receiving data is causing them problems (rather than it being
broadcast packets in particular).  You could try sending a UDP stream at
the board (which should just drop the packets if there is nothing
listening to receive them) and see what that does.
