Yes I am referencing them, but still they are not interacting with the tap

Yes, they are not. But the tap driver code references them. I mean, you
might have done that wrongly. e.g., the build passes if I removed few
includes for linux header files:

    diff --git a/drivers/net/tap/rte_eth_tap.c b/drivers/net/tap/rte_eth_tap.c
    index 4621c55..2a6bcd0 100644

It would seem like you could delete all of the code in the tap driver
and still get these errors. Which you could try if you want, just ifdef the
code and see if it still happens. 

On my ubuntu 16.04 machine I do not get these errors. I need to know how to
reproduce the failure to fix it. 

Interesting! I really did no magic to reproduce it. As said, I can
reproduce it pretty easily with ubuntu 16.04 and fedora 20, just with
default build:

    $ make install T=$RTE_SDK

Anyway, the error is straightforward after all: both files (net/if.h and
linux/if.h) define same structures and macros. Including both of them
would result errors like I reported.
