So think of it as: #define rcu_dereference(x) (x) That test in net/core/dev.c says: if packet is loopback or device is not a member of a bridge then return 0 (don't pass it to bridge) Are you sure that the ethernet device you are using correctly sets the pkt_type and the device pointer on received packets before calling netif_receive?
