Subject: [PATCH net-next 4/4] ice: update representor when VSI is ready

From: Michal Swiatkowski <michal.swiatkowski@...ux.intel.com>

In case of reset of VF VSI can be reallocated. To handle this case it
should be properly updated.

Reload representor as vsi->vsi_num can be different than the one stored
when representor was created.

Instead of only changing antispoof do whole VSI configuration for
eswitch.
