Large ping packets crash the FRDM-k64F

On the frdm-K64F sending a large ping packet crashes the board. The stack sends a response once, but does not seem to return to the executing program.

After I issue:

ping -s 4096 192.168.1.20

the led will stop blinking and no further responses are returned.

Thanks for reporting this Marius. We'll have a look at it.

Hi Sam,

There may be a clue here.

See my note regarding lwip-eth on that thread. 4K pings work for me. Pings work up to 8193 bytes before I no longer get a Ping response. Also, the K64F doesn't crash, it just fails to respond to very large Pings.
