[dpdk-dev] [PATCH v2] drivers/octeontx2: fix recursive qint interrupts

[Harman Kalra]

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.

Fixes: dc47ba15f645 ("net/octeontx2: handle queue specific error interrupts")
Fixes: 50b95c3ea7af ("mempool/octeontx2: add NPA IRQ handler")
