Re: [dpdk-dev] 82599 feature request: loopback and TSO

[jigsaw <jigsaw@gmail.com>]

Hi Thomas,

Thanks for reply. 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.
