Thanks for your information. I can include "linux/types.h"
where are defined these typedefs (i think its what you mean):

typedef __u16 __bitwise __le16;
typedef __u16 __bitwise __be16;
typedef __u32 __bitwise __le32;
typedef __u32 __bitwise __be32;

but where are these ????
typedef __u8 __bitwise __le8;
typedef __u8 __bitwise __be8;

are they missing or am _I_ missing something ???
