From f5426250a6ecfd1e9b2d5e0daf07565f664aa67d Mon Sep 17 00:00:00 2001 From: Paolo Abeni Date: Fri, 9 Mar 2018 10:39:24 +0100 Subject: net: introduce IFF_NO_RX_HANDLER Some network devices - notably ipvlan slave - are not compatible with any kind of rx_handler. Currently the hook can be installed but any configuration (bridge, bond, macsec, ...) is nonfunctional. This change allocates a priv_flag bit to mark such devices and explicitly forbid installing a rx_handler if such bit is set. The new bit is used by ipvlan slave device.
