Bit shifting and bit manipulating code like 

[...]
imp <<= 8; imp |= min(max(device[i]->Priority() + MAXPRIORITY, 0), 
0xFF);
imp <<= 8; imp |= min(max(device[i]->ProvidesCa(Channel), 0), 0xFF);
[...]

is hard to read and makes it difficult to understand the whole algorithm 
without documentation.
Personally I prefer to use bit manipulating operations only where it is 
unavoidable.
