Only way to enable switchdev is to create VFs when the eswitch mode is set to switchdev. Check if correct mode is set and enable switchdev in function which creating VFs. Disable switchdev when user change number of VFs to 0. Changing eswitch mode back to legacy when VFs are created in switchdev mode isn't allowed. As switchdev takes care of managing filter rules, adding new rules on VF is blocked. In case of resetting VF driver has to update pointer in ice_repr struct, because after reset VSI related things can change.
