Try to restart your tc config?

The statistics are stored in the driver but you can
write a kernel module calling get_stats for each netdevice
and set them to 0.

struct net_device *dev;

rtnl_lock();
read_lock(&dev_base_lock);
for (dev = dev_base; dev; dev = dev->next) {
   struct net_device_stats *s = dev->get_stats();
   memset(s, 0, sizeof(*s));
}
read_unlock(&dev_base_lock);
rtnl_unlock();

Both, dev_base and dev_base_lock are exported symbols.
Not tested but might work.
