>
> When users configure rxds and txds by used port config cmd based on
> testpmd application, it will not be able to configure rxd and txd according to
> the max capability range supported by the actual NIC hardware. Due testpmd
> defects, it can only configure a fixed range to 0 to 2048.
> The final result is that an incorrect printing prompt appears and cannot be
> applied using rxd && txd according to the actual capabilities supported by the
> device.
> In order to solve the above problems, we modify the testpmd. First by calling
> the rte_eth_dev_info_get api to obtain the max and min rx/tx capability
> supported by the hns3, and then use this range to compare with the actual
> value by users configured and make reasonable limitation.
