Probably some copy-paste error from "int_msix" that caused "int_" prefix to
appear in the comments for all "eq_" APIs.

Currently, the mlxsw spectrum driver only supports offloading the matchall
classifier together with the mirred action. To allow more matchall tc
offloads, make the code symmetric so that it can be easily extended later
on for other actions.
