RSS don't work when bond_ethdev_configure called before
rte_eth_bond_slave_add.
e.g.:
dont't work(examples/bond/main.c):
rte_eth_bond_create()
rte_eth_dev_configure()
rte_eth_bond_slave_add()
rte_eth_dev_start()
work(testpmd):
rte_eth_bond_create()
rte_eth_bond_slave_add()
rte_eth_dev_configure()
rte_eth_dev_start()
