- * lpfc_sli_replace_hbqbuff: Replace the HBQ buffer with a new buffer.
- * @phba: Pointer to HBA context object.
- * @tag: Tag for the HBQ buffer.
- *
- * This function is called from unsolicited event handler code path to get the
- * HBQ buffer associated with an unsolicited iocb. This function is called with
- * no lock held. It returns the buffer associated with the given tag and posts
- * another buffer to the firmware. Note that the new buffer must be allocated
- * before taking the hbalock and that the hba lock must be held until it is
- * finished with the hbq entry swap.
