 * The SLI interface allows only one mailbox pending at a time. If the

 * in NO_WAIT mode and there is a mailbox pending already, the function
 * will return MBX_BUSY after queuing the mailbox into mailbox queue.

 *
 * __lpfc_sli_issue_iocb_s3 is used by other functions in the driver to issue
 * an iocb command to an HBA with SLI-3 interface spec. If the PCI slot is
 * recovering from error state, if HBA is resetting or if LPFC_STOP_IOCB_EVENT
 * flag is turned on, the function returns IOCB_ERROR. When the link is down,
 * this function allows only iocbs for posting buffers. This function finds
 * next available slot in the command ring and posts the command to the
 * available slot and writes the port attention register to request HBA start
 * processing new iocb. If there is no slot available in the ring and
 * flag & SLI_IOCB_RET_IOCB is set, the new iocb is added to the txq, otherwise
 * the function returns IOCB_BUSY.
 *
 * This function is called with hbalock held. The function will return success
 * after it successfully submit the iocb to firmware or after adding to the
 * txq.

 * This function is directly called from the PCI layer as an interrupt
 * service routine when device with SLI-3 interface spec is enabled with
 * MSI-X multi-message interrupt mode and there are slow-path events in
 * the HBA. However, when the device is enabled with either MSI or Pin-IRQ
 * interrupt mode, this function is called as part of the device-level
 * interrupt handler. When the PCI slot is in error recovery or the HBA
 * is undergoing initialization, the interrupt handler will not process
 * the interrupt. The link attention and ELS ring attention events are
 * handled by the worker thread. The interrupt handler signals the worker
 * thread and returns for these events. This function is called without
 * any lock held. It gets the hbalock to access and update SLI data
 * structures.
 *
 * This function returns IRQ_HANDLED when interrupt is handled else it
 * returns IRQ_NONE.
