   @davids5 I tested your changes on my board and have had no issues for the last 20 minutes using the default packet size of 590. Previous, all it took was plugging the board into my network, which would lead to a hard fault in less than 15 seconds. Network debug output shows it is receiving large packets that are being broken up into segments. I have TCP, UDP, and ICMP all enabled. Looks like your fix did the trick!
