-Enabling Extended Tag
-~~~~~~~~~~~~~~~~~~~~~
-

-performance of 40G ports. Enabling ``extended_tag`` can help 40G port to
-achieve the best performance, especially for small packet size.
-
-* Disabling/enabling ``extended_tag`` can be done in some BIOS implementations.
-
-* If BIOS does not enable it, and does not support changing it, tools
-  (e.g. ``setpci`` on Linux) can be used to enable or disable ``extended_tag``.

-  initialization, users don't need to care about that anymore.
