 * @pcie_callbk_data: Callback data to be passed to the PCIe callback functions.
 * @pcie_prb_callbk: The callback function to be called when a PCIe device

 * @pcie_rem_callbk: The callback function to be called when a PCIe device

 * This structure maintains the context information necessary for the operation
 * of the Linux shim. Some of the elements of the structure need to be
 * initialized during the initialization of the Linux shim while others need to
 * be kept updated over the duration of the Linux shim operation.
