System for rescheduling cascaded callback functions to complete an asynchronous physical layer initialization process

An apparatus for establishing a computer network connection utilizing asynchronous physical layer initialization, the apparatus comprising:

• a computer connection member for connecting the apparatus to a computer system;
• a network connection member for connecting the apparatus to a network;
• a processor;
• and
• a software driver adapted to be executed by the processor at direction of an operating system of the computer system for operation of the apparatus, the software driver including,
• instructions for scheduling a callback function, the callback function performing a function of the physical layer initialization that requires a waiting period,
• instructions for executing the callback function,
• instructions for determining whether the-callback function was completed after at least one other system software code is executed while the physical layer initialization is still being conducted,
• instructions for rescheduling the callback function if the callback function was incomplete, and
• instructions for scheduling another callback function if required to complete the physical layer initialization.

A computer system comprising:

• a network adapter connected to the computer system;
• an operating system executing on the computer system;
• and
• a software driver adapted to be executed by a processor at direction of the operating system for operation of the network adapter, the software driver including,
• instructions for scheduling a callback function, the callback function performing a function of physical layer initialization that requires a waiting period,
• instructions for executing the callback function,
• instructions for determining whether the callback function was completed after at least one other system software code is executed while the physical layer initialization is still being conducted,
• instructions for rescheduling the callback function if the callback function was incomplete, and
• instructions for scheduling another callback function if required to complete the physical layer initialization.

A computer program system for asynchronous physical layer initialization, the computer program system comprising:

• a computer-readable medium;
• and
• computer-readable program code, stored on the computer-readable medium, adapted to be loaded and executed on an operating system of a computer system for operation of a network adapter, the computer-readable program code performing,
• scheduling a callback function, the callback function performing a function of the physical layer initialization that requires a waiting period,
• executing the callback function,
• determining whether the callback function was completed after at least one other system software code is executed while the physical layer initialization is still being conducted,
• rescheduling the callback function if the callback function was incomplete, and
• scheduling another callback function if required to complete the physical layer initialization.
