filter and names should be const, i.e won't get modified by call.
.
The "filter" can be a pointer to a const string. It's OK to add const.
The "names" could be modified. The APPs are free to assign space for
regisger names and "names" point to the first element.
And the ethdev and drivers are free to modifiy each element.
