- * lpfc_sli4_hba_down - PCI function resource cleanup for the SLI4 HBA
- * @phba: Pointer to HBA context object.
- *
- * This function cleans up all queues, iocb, buffers, mailbox commands while
- * shutting down the SLI4 HBA FCoE function. This function is called with no
- * lock held and always returns 1.
- *
- * This function does the following to cleanup driver FCoE function resources:
- * - Free discovery resources for each virtual port
- * - Cleanup any pending fabric iocbs
- * - Iterate through the iocb txq and free each entry in the list.
- * - Free up any buffer posted to the HBA.
- * - Clean up all the queue entries: WQ, RQ, MQ, EQ, CQ, etc.
- * - Free mailbox commands in the mailbox queue.
