Hereunder the patch for Tx->Rx loopback operation for 82599. Note that Rx->Tx is not implemented yet. The patch is tested with a Intel Corporation 82599EB 10-Gigabit KX4 Network Connection. If the patch could be accepted then Rx->Tx could be implemented on top of it. https://gist.github.com/jigsawecho/6671630 On Mon, Sep 23, 2013 at 11:42 AM, Thomas Monjalon wrote: > Hello, > > 22/09/2013 20:01, jigsaw : > > Is there any plan for adding support for 82599 features such as: > > > > 1.
