example:lwip_s32K148
I'll look at the code for this example,I have ported LWIP protocol on 5748 before，In contrast, there are some questions。
When self-porting, the interface corresponding to the low driver is:low_level_output 、low_level_input、low_level_input. in function low_level_input,Initializing a network adapter.but int the lwip_S32k148,i just found function: 'enetif_low_level_output'、'enetif_low_level_init',don't found about filed ' low_level_input'? where do i found this function.
i check help doc 'lwip_s32k148_group.html',but hasn't any introduce.
in this example, enet recevie data ,dose trigger interrupt?
I want use MQTT protocal,dose has any example?
