Wireshark-dev: Re: [Wireshark-dev] RRC Messages does not decode correctely

Hi,
The problem is how to handle bitstrings of 17-65k bits length
I don't really fancy doing
for(i=0;i<min_len;i++){
	offset=dissect_per_boolean(tvb, offset, actx, tree, -1, &bit);
	bytes[0]=(bytes[0]<<1)|bit;
}
Etc for 65k long ones...

I don't know how usual really long bitstrings are perhaps we could only
display the value for the ones up to 32 bits?

Would a display like
...0 0000 (etc) 00.. Be better?
Regards
Anders

Hej Anders

As referense how the value should be decoded (the bitstring are in hex 
in wireshark).
