All these are permanent; none are temporary - that's (partially) why
we consider these to be devlink/device parameters rather than a
netdev/ethtool thing, since they take effect after the next reset and
before any drivers are loaded (i.e. the card uses these parameters for
its default/startup configuration).

I will take a closer look at splitting these between per-port and per-asic.
