Hey,

Has anyone experimented with filtering out packets from a specific ip addresses with the LPC1768 and LAN8720? (I'm using lwip and freeRTOS)

I'm having an issue when one of my high bandwidth streaming devices is running on the network at the same time that I'm trying to receive a different stream, seems like the PHY is just constantly receiving stuff, and the processor can't keep up with it.

If I use a multicast switch, I don't have the problem because then my device only receives packets from the specific multicast group that it joins.
