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"

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.

Hi,
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 10G
port.
2. TCP/UDP segmentation in Tx (TSE bit in DCMD)
TSO implementation is already in kernel. Is it in the roadmap of DPDK?
thx &
rgds,
-Qinglai Xiao
