      LPDC link stability fix - EP MDIO read race condition · f8febec6
      Grzegorz Daniluk authored
      Since driver reads periodically MDIO registers (timer function to check
      link state) and HAL reads periodically LPDC MDIO registers (through
      ioctl call) it happened once in a while that ioctl read operation would be
      interleaved with timer function. As a result HAL would get the value
      read from a different MDIO register than the one requested. This had
      caused occasional link restarts on LPDC ports.
