In the i350 ethernet datasheet, the RXDCTL and TXDCTL registers define the fields of the pthreshold, hthreshold and wthreshold. And i can find that the igb dpdk driver manipulates this registers. But i can't find the similar functions in the XL710's dpdk driver. Can i change the rxpt/rxht/rxwt values? Which function achieves it in XL710 dpdk driver? Can you help me?
