  When use i40e linux kernel driver as host driver and DPDK handler the i40e
VF, the promiscuous mode doesn't work in i40e VF. It is not supported by
DPDK i40e VF driver right now.

+I40e VF may not receive packets in the promiscuous mode
+-------------------------------------------------------
+
+**Description**:
+   Promiscuous mode is not supported by the DPDK i40e VF driver when using the
+   i40e Linux kernel driver as host driver.
+
+**Implication**:
+   The i40e VF does not receive packets when the destination MAC address is unknown.
+
+**Resolution/Workaround**:
+   Use a explicit destination MAC address that matches the VF.
+
+**Affected Environment/Platform**:
+   All.
+
+**Driver/Module**:
+   Poll Mode Driver (PMD).
