> Hi everybody,
> I tried to run the packet transmittng code (Chap 9) from 
> IXP1200 programming 
> book. In function "bridging.c", hashIO_t has structure like:

> typedef struct {
> 	unsigned int	hash_lo32;
> 	unsigned int	hash_hi16 : 16;
> 	unsigned int 	pad : 16;
> } hashIO_t;
> If I compile the code, it gives an error regarding 
> "hash_hi16: 16" field:
> "error :  intrinsic data buffer "hashInput_103$1$0" cannot be read"
> 
> But if I remove specifying the number of bits I mean only 
> "unsigned int 
> hash_hi16" it compiles fine, though logically it's not correct.
