net: mana: Increase the DEF_RX_BUFFERS_PER_QUEUE to 1024
Through some experiments, we found out that increasing the default
RX buffers count from 512 to 1024, gives slightly better throughput
and significantly reduces the no_wqe_rx errs on the receiver side.
Along with these, other parameters like cpu usage, retrans seg etc
also show some improvement with 1024 value.
Following are some snippets from the experiments
ntttcp tests with 512 Rx buffers
---------------------------------------
connections| throughput| no_wqe errs|
---------------------------------------
1 | 40.93Gbps | 123,211 |
16 | 180.15Gbps | 190,120 |
128 | 180.20Gbps | 173,508 |
256 | 180.27Gbps | 189,884 |
ntttcp tests with 1024 Rx buffers
---------------------------------------
connections| throughput| no_wqe errs|
---------------------------------------
1 | 44.22Gbps | 19,864 |
16 | 180.19Gbps | 4,430 |
128 | 180.21Gbps | 2,560 |
256 | 180.29Gbps | 1,529 |
So, increasing the default RX buffers per queue count to 1024
