[c-nsp] 10/25 interface behavior

[Gehring Kai]

At least on the Catalyst 9000 series it looks like they switched to always using the highest bandwidth that would potentially be available on that interface... just checked on a 9200L and a 9500-16X: The interface name is always TenGigabitEthernet, even if you use 1Gbit SFPs in them.

Much better imho, different interface names with different transceivers is just such a pain..
