To reproduce\nthis[1], one bond device (bond1) has xdpdrv, which increases\nbpf_master_redirect_enabled_key. Another bond device (bond0) which is\nunsupported by XDP but its slave (veth3) has xdpgeneric that returns\nXDP_TX. This triggers WARN_ON_ONCE() from the xdp_master_redirect().\nTo reduce unnecessary warnings and improve log management, we need to\ndelete the WARN_ON_ONCE() and add ratelimit to the netdev_err().\n\n[1] Steps to reproduce:\n    # Needs tx_xdp with return XDP_TX;\n    ip l add veth0 type veth peer veth1\n    ip l add veth3 type veth peer veth4\n    ip l add bond0 type bond mode 6 # BOND_MODE_ALB, unsupported by XDP\n    ip l add bond1 type bond # BOND_MODE_ROUNDROBIN by default\n    ip l set veth0 master bond1\n    ip l set bond1 up\n    # Increases bpf_master_redirect_enabled_key\n    ip l set dev bond1 xdpdrv object tx_xdp.o section xdp_tx\n    ip l set veth3 master bond0\n    ip l set bond0 up\n    ip l set veth4 up\n    # Triggers WARN_ON_ONCE() from the xdp_master_redirect()\n    ip l set veth3 xdpgeneric object tx_xdp.o section xdp_tx"
