| Doc Text: |
In RHOSP 17.1.4, a technology preview is available to avoid link flapping on OVS-DPDK bonds when the links are over subscribed. This enhancement is achieved by setting the `rx-steering=lacp+rss` option on every member of the DPDK bond.

.Example:

[source,bash]
----
$ ovs-vsctl add-bond br-dpdk0 dpdkbond0 dpdk0 dpdk1 -- \
set interface dpdk0 type=dpdk options:dpdk-devargs=0000:ca:00.0 \
options:rx-steering=rss+lacp -- \
set interface dpdk1 type=dpdk options:dpdk-devargs=0000:ca:00.1 \
options:rx-steering=rss+lacp
