Iremonger, Bernard Dec. 13, 2016, 11:40 a.m. UTC
Move the following functions from eth_dev_ops to the ixgbe PMD and rename:

ixgbe_set_pool_rx_mode
ixgbe_set_pool_rx
ixgbe_set_pool_tx
ixgbe_set_pool_vlan_filter
ixgbe_set_vf_rate_limit

Rename the functions to the following:

rte_pmd_ixgbe_set_vf_rxmode
rte_pmd_ixgbe_set_vf_rx
rte_pmd_ixgbe_set_vf_tx
rte_pmd_ixgbe_set_vf_vlan_filter
rte_pmd_ixgbe_set_vf_rate_limit

Use public function internally
