Disable TCP in lwIP with 0 connections

When I disable TCP of the lwIP in CubeMX and set the MEMP_NUM_TCP_PCB to 0, I can't compile without error 

MEMP_NUM_TCP_PCB has to be > 0.

Seems like a bug?

Hi Stefan, ,

Yes I confirm, ' ♯ define ,LWIP_TCP 0' is no generated in lwipopts.h when the TC is disabled. ,

Please add it manually and it will be fixed for the 4.26.1
