Hi Team,
I am facing *ovs|00001|dpif_netlink(handler13)|ERR|failed to offload
flow: Protocol error: ens85npf0vf2 on *OVS 3.2.2. Ovs-vswitchd is
continuously throwing this error. Is this a known issue? Will there be any
traffic impact with respect to packet loss?
Please find the captured logs below.
Thanks in advance,
Srini
