Arduino IDE Ethernet2.h W5500 Chipset -

i've got bad problem new ethernet shield 2 arduino. has got chipset w5500 instead of w5100 therefore ethernet2.h has used instead of ethernet.h.
here little code snippet.

// if the ethernet shield 2 (chip w5500)  used have use ethernet2.h #include <ethernet2.h>  // if ethernet shield 1 (chip w5100)is used have use ethernet.h //#include <ethernet.h>   #include <comstack.h> #include <requiredmessagecallbacks.h> 

unfortunately header files comstack , others need ethernet.h header compile. create header file inside project folder because project rebased other branches. tried different things lot of workarounds not solution. has got hint problem.

thank in advance.
