In releng/13 there is also infiniband/byteswap.h that does:

#include <sys/types.h>
#include <sys/endian.h>

#define bswap_16=C2=A0 =C2=A0 =C2=A0 =C2=A0 bswap16
#define bswap_32=C2=A0 =C2=A0 =C2=A0 =C2=A0 bswap32
#define bswap_64=C2=A0 =C2=A0 =C2=A0 =C2=A0 bswap64
That works too. The reason I suggested what I did is that it a= lso lets you do #undef bswap16, etc if your software needs it.
