Subject: [PATCH net] ice: block LAN in case of VF to VF offload
From: Michal Swiatkowski <michal.swiatkowski@...ux.intel.com>
VF to VF traffic shouldn't go outside. To enforce it, set only the loopback
enable bit in case of all ingress type rules added via the tc tool.
Fixes: 0d08a441fb1a ("ice: ndo_setup_tc implementation for PF")
