Hi Team members, We are trying to experiment the TC qdisc behaviour with hw-offload enabled(Kernel offload using TC). Need clarification on below queries.
1. As part of HW Offload being enabled on OVS (using ovs-vsctl set Open_vSwitch . other_config:hw-offload=true), we are observing that the TC INGRESS QDISC is always getting created by OVS on addition of tap to bridge. Please can you help us in understanding why this is being added to all the ports which are participating in the bridge ? Our understanding is that virtual port like tap won’t be participate in HW offload. 2. We also wanted to understand the reason behind keeping the TC INGRESS QDISC creation as Exclusive flag. We are trying to supplement this with another qdisc (tc qdisc add dev tap0 clsact) but the creation itself is failing since the current INGRESS qdisc is kept with Exclusivity flag turned on. Thanks in advance, Rama Chaitanya
