Hi Thomas

It has already been mentioned in getting started guide for a long time.
Are you suggesting to move into i40e specifically? Thanks!

Regards,
Helin

2015-12-21 10:38, Helin Zhang:

PCIe feature of 'Extended Tag' is important for 40G performance.
It adds its enabling during each port initialization, to ensure the 
high performance.

If it's so important, why the values are not documented?
Please start to fill a file doc/guides/nics/i40e.rst to explain how the device works.
Thanks
