Hi Sean, Do you happen to have any details on the bug? I note that the IPv6 header DOES NOT HAVE a checksum; it relies on the checksum in the layer-2 frame. I'm not clear how you "append" bytes to the ethernet frame "after" calculating the checksum, have the hardware checksum fail but have the software checksum succeed.
