Hi,
I study hash optimization in network, and I know that rte_softrss()
function in DPDK lib(rte_thash.h) which implements RSS. And then, I guess
that its value is same with NIC RSS(hardware).
I get NIC RSS by call 'le32_to_cpu(rx_desc->wb.lower.hi_dword.rss)';
However, I printed NIC RSS's value and Soft RSS value, and two values is
different. I thought that because of little endian, they are different. So
I change the call with 'be32_to_cpu(rx_desc->wb.lower.hi_dword.rss)'. But,
the result is same
Is my guess wrong?
Please let me know if you have any insights.
