netem: loss model API sizes
The new netem loss model is configured with nested netlink messages. This code is being overly strict about sizes, and is easily confused by padding (or possible future expansion). Also message for gemodel is incorrect. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
