I’m following NVIDIA DOCS ASAP port mirroring to capture packets with CX5. (OVS Offload Using ASAP² Direct - NVIDIA Docs)
However, it is not allowed to truncate the packets via
snaplen options once the flow is offloaded. In my opinion, it is because the ASAP datapath actions do not have
trunc. Further, the
output(port, max_len) action is not available due to not implemented
trunc actions in H/W dp.
Then, is there any good approach to do
ASAP2 H/W offloading and
packet truncation simultaneously?
