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

Set egress (Rx) pruning enable flag for vf vsi in vsi ctxt to
enable prune action.

To avoid seeing broadcast packet in different vlan, pruning enable
flag in vsi ctxt should be set.

Write new functions (fill vsi ctx) to not repeat send ctxt code.
