In the driver currently, we are reporting max number of TCs
to the DCBNL callback as a kernel define set to 8.  This is
preventing userspace applications performing DCBx to correctly
down map the TCs from requested to actual values.

Report the actual max TC value to userspace from the capability
struct.
