The Attribute is defined in the dictionary as:
ATTRIBUTE	3GPP-GPRS-Negotiated-QoS-profile	5	string
The Value of a String might be: 99-0B811F7396878774010000
To get the encapsulated "Traffic Class", I will need the most left 3 bits of
the first '7' of the string.
It would be 7 --> 0111  -->  011  -->  3
Ugh.  Why do people design such complicated protocols?

Is there a function available, to do this?
No.

  FreeRADIUS doesn't support bit-packed structures.  There isn't a lot
of reason to do that, because Perl does it much better.
