Technically Seville is not part of the Ocelot family but part of
Serval, but then again, it's just a marketing name, so it doesn't
really mean anything..
I am a bit reluctant to rename the DSA driver ops to "ocelot", since
it would be even more confusing for everyone to have a function
ocelot_dsa_set_ageing_time that calls ocelot_set_ageing_time. At least
this way, there's going to be some learning curve figuring out that
felix is an umbrella term for DSA ops, but there will be more naming
predictability. (at least that's how I see it)

How would you see the merged MAINTAINERS entry? Something like this?

Any takers from Microchip, or is the internal mailing list enough?
