[dpdk-dev] [PATCH v3 12/15] net/i40e/base: fix Rx only mode for unicast promisc on VLAN

[Guinan Sun]

Set promiscuous mode to rx traffic only if VSI has VLANs configured.
Rename misleading PROMISC_TX bit to proper name.
Added I40E_AQC_SET_VSI_PROMISC_RX_ONLY during VSI unicast promiscuous
mode configuration with port VLAN.
Aligned unicast promiscuous with VLAN to the one without VLAN.
Previously other VFs could listen to unicast tx traffic of other VFs.
