Instead of moving from "known_issues.rst" to "i40e.rst",
does it make sense to create a sub-section in "known_issues.rst" for
I40E and move these items under that sub-section,
and give a link in "i40e.rst" to that section?
Hi, Ferruh
It's a good way, I'll send a new patch. Thank you.

+Promiscuous mode is not supported by the DPDK i40e VF driver when using

+packets when the destination MAC address is unknown. Use a explicit
