Once Hardware evicts the EPVA TCP flows due to Idle timeout, tmm does not reinsert the flows back when it receives a packet belonging to that flow.
Performance can be impacted. Hardware acceleration will be disabled for the flows once the flow is removed from hardware due to Idle timeout.
This occurs when the TCP connection is kept idle for ~20 seconds.
None
Fix will re-offload the flows to HW once SW starts receiving packets due to HW eviction of flows by Idle timeout.
