address\ninspite PF has set a forced MAC for that VF from HV.\n\nEarlier similar functionality is provided by module parameter\n\"allow_vf_mac_change_mode\" of qed.\n\nThis change makes few changes in behavior of VF shadow config -\n - Let driver track the VF mac in shadow config as long as trust\n mode is OFF.\n - Once trust mode is ON, we should not care about MACs in shadow\n config (because we never intend to fall back because of lack of restore\n implementation).\n - Delete existing shadow MAC (this helps when trust mode is turned OFF,\n and VF tries to add new MAC – it won’t fail that time since we have\n a clean slate).\n - Skip addition and deletion of MACs in shadow configs.\n\nSigned-off-by: Shahed Shaikh <shahed.shaikh@cavium.com>\n---\n drivers/net/qede/base/ecore_iov_api.h |
