  1. Transmitter path
    1. MAC latency: 48 ns
    2. PCS latency: 64 ns
    3. GT Latency: 84 ns

      Total TX latency: 1.a + 1.b + 1.c = 48 + 64 + 84 = 196 ns

      Value in hex for TX latency: 0xC4

  2. Receiver path
    1. MAC latency: 8 ns
    2. PCS latency: 56 ns
    3. GT latency: 113 ns

    Total RX latency: 2.a + 2.b + 2.c = 8 + 56 +113 = 177 ns.

    Value in hex for RX latency: 0xB1.
