When Rx of scattered packets is off, we have some possibility of using vector Rx process function or simple Rx functions in hns3 PMD driver. If the input MTU is increased and the maximum length of received packets is greater than the length of a buffer for Rx packets, the hardware network engine needs to use multiple BDs and buffers to store these packets. This will cause problems when still using vector Rx process function or simple Rx function to receiving packets. So, when Rx of scattered packets is off and device is started, it is not permitted to increase MTU so that the maximum length of Rx packets is greater than Rx buffer length.
