Same question as in the previous patch, surf[6] ?

The way I read the spec, I would have written this as:

            aux_str = msrt ? "AUX_CCS_E [MCS]" : "AUX_CCS_E [CCS]";

Ande the one below:

            aux_str = msrt ? "AUX_CCS_D [MCS]" : "AUX_CCS_D [CCS]";

But maybe I'm misreading.

Missing break?
