Yes, that would be O.K.
It cannot be too long a prefix. The maximum length of the name is
32. The header file is unclear if there must be a NULL at the end. It
looks like the longest switch statistic we have is
RxPkts1024toMaxPktsOctets, i.e. 25 characters. So we only have 6 or 7
characters for the prefix.
