[dpdk-dev] [PATCH v1 1/5] net/ixgbe: move set VF functions from the ethdev

Bernard Iremonger bernard.iremonger at intel.com
Fri Dec 9 12:17:45 CET 2016


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
