Race condition prevention

An apparatus comprising:

• circuitry capable of:
• in response, at least in part, to one or more received frames, generate an interrupt and prevent transmission of one or more other frames, the one or more received frames indicating, at least in part, an error condition or a commencement of a data transfer;
• and
• in response, at least in part, to the interrupt, execute one or more instructions, the one or more instructions, when executed, resulting in:
• if the one or more received frames indicate, at least in part, the error condition, commencing recovery from the error condition;
• and
• if the one or more received frames indicate, at least in part, the commencement of the data transfer, storing data associated with the data transfer.

One or more storage media storing instructions that when executed by a machine result in performance of operations comprising:

• in response, at least in part, to one or more received frames, generating an interrupt and preventing transmission of one or more other frames, the one or more received frames indicating, at least in part, an error condition or a commencement of a data transfer;
• and
• in response, at least in part, to the interrupt, executing one or more other instructions, the one or more other instructions, when executed, resulting in:
• if the one or more received frames indicate, at least in part, the error condition, commencing recovery from the error condition;
• and
• if the one or more received frames indicate, at least in part, the commencement of the data transfer, storing data associated with the data transfer.

A system comprising:

• a circuit card capable of being inserted in a circuit card slot that is comprised in a circuit board, the circuit card comprising:
• circuitry capable of:
• in response, at least in part, to one or more received frames, generate an interrupt and prevent transmission of one or more other frames, the one or more received frames indicating, at least in part, an error condition or a commencement of a data transfer;
• and
• in response, at least in part, to the interrupt, execute one or more instructions, the one or more instructions, when executed, resulting in:
• if the one or more received frames indicate, at least in part, the error condition, commencing recovery from the error condition;
• and
• if the one or more received frames indicate, at least in part, the commencement of the data transfer, storing data associated with the data transfer.
