Next hardware will direct packets to core based on the TCP/UDP streams. This logic can create holes in reorder buffer since packets that belong to other stream were directed to a different core. However, those are valid holes and the packets can be indicated in L3 order. The hardware will utilize a mechanism of informing the driver of the normalized ssn and the driver shall release all packets that SN is lower than the nssn. This enables managing the reorder across the queues without sharing any data between them. The reorder buffer is allocated and released directly in the RX path in order to avoid various races between control path and rx path. The code utilizes the internal messaging to notify rx queues of when to delete the reorder buffer.
