There is a bug in the rate limiting, for the type of int has a max limit 2147483648,(lt 2000000*1000)
if you can change type 'int' to 'uint' in the function context, as follow,
static int tc_add_policer(struct netdev *netdev, int kbits_rate, int kbits_burst)

qdiscs only control the rate of data transmission, not reception.  You
might want to use policing, please see ovs-vswitchd.conf.db(5) for
configuration details.
