> In case of QINT interrupt occurrence, SW fails to clear the QINT line resulting
> in recursive interrupts because currently interrupt handler gets the cause of
> the interrupt by reading NIX_LF_RQ[SQ/CQ/AURA/POOL]_OP_INT but does
> not write 1 to clear RQ[SQ/CQ/ERR]_INT field in respective
> NIX_LF_RQ[SQ/CQ/AURA/POOL]_OP_INT registers.
