有给FreeRTOS TCPIP协议栈增加PPP支持的(PPPOS)打算吗?

I am trying to add pppos function to freertos-tcpip.
I set ipconfiguse_ DHCP = 0, when the program starts to run, I give FreeRTOS_ Ipinit() function invalid IP, mask, gateway, DNS, etc.
When I get the IP address through the 4G module, I directly call FreeRTOS_ Setipaddress() function and xnetworkaddressing.ulDNSServerAddress = ppp->ipcp_ Is dns1 OK.
Do I need to stop FreeRTOS TCPIP and reinitialize it?
