These indicate that userspace is sending a broken command stream (e.g., a bad
count for a packet most likely).  The kernel will reject the command stream if
a bad one is encountered.  There still could be a bug in the command stream
setup in userspace that is just masked in other cases due to the layout of the
commands.
