> Previously, the ice driver had support for using a hanldler for bonding
> netdev events to ensure that conflicting features were not allowed to be
> activated at the same time.  While this was still in place, additional
> support was added to specifically support SRIOV and LAG together.  These
> both utilized the netdev event handler, but the SRIOV and LAG feature was
> behind a capabilities feature check to make sure the current NVM has
> support.
>
> The exclusion part of the event handler should be removed since there are
> users who have custom made solutions that depend on the non-exclusion of
> features.
>
> Wrap the creation/registration and cleanup of the event handler and
> associated structs in the probe flow with a feature check so that the
> only systems that support the full implementation of LAG features will
> initialize support.  This will leave other systems unhindered with
> functionality as it existed before any LAG code was added.
