Re: 82599 feature request: loopback and TSO

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.

Is there any plan for adding support for 82599 features such as:

1. Loopback operation for diagnostic purpose
The Tx->Rx loopback operation is handy when debugging with a standalone

port.

2. TCP/UDP segmentation in Tx (TSE bit in DCMD)
TSO implementation is already in kernel. Is it in the roadmap of DPDK?

I'll reword your question to "Is there anybody who is willing to
send patches for these features ?"

Note that a patch from Ivan Boule (6WIND) has already been integrated to
provide capabilities of the devices:
        "ethdev: add support for device offload capabilities"
