Hash rss value with mprq_en=1 device parameter

[Дмитрий Степанов]

Hi folks!

I'm using Mellanox ConnectX-6 Dx EN adapter card (100GbE; Dual-port QSFP56;
PCIe 4.0/3.0 x16) with DPDK 21.11.
I'm setting mprq_en=1 device parameter to increase rx performance. But in
that case, rte_mbuf's field `hash.rss` of the received frame is zero and
`RTE_MBUF_F_RX_RSS_HASH` flag of field `ol_flags` is not set.
Without mprq_en=1 i get valid `hash.rss` value and flag
`RTE_MBUF_F_RX_RSS_HASH` is set.
Is there any way to get valid `hash.rss` value with mprq_en=1?

Thanks,
Dmitriy Stepanov
