      The High-Performance Networking Stack (io-sock) was introduced for QNX SDP 7.1 as a replacement for the io-pkt networking stack and is updated for QNX SDP 8.0.
      - Modifying a BSP to support io-sock
        If QNX does not provide a BSP that supports io-sock for your target hardware, you need to create one. To simplify the process, QNX recommends that you start with the io-sock-compatible BSP provided by QNX that most closely matches your target's specifications.
      - Migrating from QNX SDP 7.1 io-pkt to QNX SDP 8.0 io-sock
        Applications that use io-pkt can be modified to use io-sock. QNX recommends the following initial modifications to make them compatible.
      - Migrating from QNX SDP 7.1 io-sock to QNX SDP 8.0 io-sock
      - Migrating io-sock networking drivers with PTP to QNX SDP 8.0.1 io-sock
