    net/mlx5e: kTLS, Add kTLS RX resync support · 0419d8c9
    Tariq Toukan authored
    Implement the RX resync procedure, using the TLS async resync API.
    
    The HW offload of TLS decryption in RX side might get out-of-sync
    due to out-of-order reception of packets.
    This requires SW intervention to update the HW context and get it
    back in-sync.
    
    Performance:
    CPU: Intel(R) Xeon(R) CPU E5-2687W v4 @ 3.00GHz, 24 cores, HT off
    NIC: ConnectX-6 Dx 100GbE dual port
    
    Goodput (app-layer throughput) comparison:
    +---------------+-------+-------+---------+
    | # connections |   1   |   4   |    8    |
    +---------------+-------+-------+---------+
    | SW (Gbps)     |  7.26 | 24.70 |   50.30 |
    +---------------+-------+-------+---------+
    | HW (Gbps)     | 18.50 | 64.30 |   92.90 |
    +---------------+-------+-------+---------+
    | Speedup       | 2.55x | 2.56x | 1.85x * |
    +---------------+-------+-------+---------+
    
    * After linerate is reached, diff is observed in CPU util.
