[dpdk-users] flow director ATR mode

[ZhangHaisen]

Hi,

I have some question about flow director ATR mode:

1.      Does DPDK support ATR mode which is described in
https://software.intel.com/en-us/articles/setting-up-intel-ethernet-flow-dir
ector as : In ATR mode, Intel Ethernet FD uses fields from the outgoing
packets in the Tx queues to populate the 8K-entry Perfect-Match filter
table.

2.      If yes , how to config the eth dev with the DPDK APIs, such as
rte_eth_dev_configure(),rte_eth_tx_queue_setup(),rte_eth_rx_queue_setup()?
Is there any example code?

 

Thanks a lot,

Zhanghaisen

The rte_flow API is what you want.
