pktgen: Fix unsigned function that is returning negative vals
Every call to num_args() immediately checks the return value for less than zero, as it will return -EFAULT for a failed get_user() call. So it makes no sense for the function to be declared as an unsigned long. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com> Signed-off-by: David S. Miller <davem@davemloft.net>
