Hello,

I suggest enhancing our RHOCP and RHOSP Networking documentation to
include "if ALG support is required, tc offload must be disabled".
This should not be a deal breaker for the OVS-DPDK customers  moving
to TC Flower offload, as OVS-DPDK has no ALG support, but I wonder
about others. At least it cannot hurt to add this mention. WDYT?

Hi Greg

Is this something we can incorporate in our OSP documentation? Please let me know if you want me to create a bz for this.

Hi,

The RHOSP 16.1 and 16.2 "NFV Planning and Configuration Guides" have been
updated. Customers can see these changes here:

   https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/16.1/html/network_functions_virtualization_planning_and_configuration_guide/ch-software#deploying_ovn_with_ovs_tc_flower_offload

   https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/16.2/html/network_functions_virtualization_planning_and_configuration_guide/ch-software#proc_deploying-ovn-with-ovs-tc-flower-offload_nfv

Customers will see the changes in the 17.0 NFV guide when those
versions are released in the future.

FTR, we also need a note saying that in 17.1, such flows are expected to not offload.
New bz then: https://bugzilla.redhat.com/show_bug.cgi?id=2208568
