  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.

The underline here is too short and generates a warning:

    doc/guides/rel_notes/known_issues.rst:626: WARNING: Title underline too short.

    I40e VF can't receive the promiscuous unicast/multicast/broadcast packet.

The text style and tense doesn't match the rest of the doc. I would suggest
something like:

   
I40e VF may not receive packets in 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 destination MAC address that matches the VF.

**Affected Environment/Platform**:
   All.

**Driver/Module**:
   Poll Mode Driver (PMD).
