Hi,

DPDK is a C code and do not support C++ compilation.
Only the exposed headers have some C++ support requirements.

Patching this file for C++ will be probably rejected, sorry.

I'm interested to understand what is your need?

Actually, dozens of h files contain this code:
#ifdef __cplusplus
extern "C" {
#endif
Less common in drivers, but also exists.


In Trex, we do include ixgbe_type.h from c++ code because we do some register writes ourselves to support some functionality not exposed in the DPDK API.
We can continue making this change in our copy of the code only. Just trying to align our code with the official version as much as possible, and thought it might benefit others as well to make this c++ compatible. 
Apart from this small change, c++ compilation is supported.

I agree we should find a way to expose some driver-specific headers for
very specific features which will never be implemented elsewhere.
But ideally, we should try to fix the DPDK API.

OK. Other comment from the maintainers (cc) of this driver?


PS: please avoid top-post.

Patch reconstructed (format was not applicable),
and applied, thanks
