nftables|bpf have access to netdev however with https://git.openwrt.org/?p=openwrt/openwrt.git;a=blob;f=target/linux/generic/config-5.4;h=cdee4c973b2d6a642dadff38a95ec45b309c2dc2;hb=refs/heads/master#l3661

# CONFIG_NF_LOG_NETDEV is not set

it is not possible:

  • to debug nftables|bpf rules applied to netdev
  • to build nftables|bpf rules from packets logged on netdev

The kconf for 5.4 is just reference, the issue though is present in all branches.

upstream reference https://github.com/torvalds/linux/blob/v5.4/net/netfilter/Kconfig#L77
