Check you kernel config, the following options should be enabled:

NETFILTER HIGH_RES_TIMERS NETLINK

Check your kernel toolchain. ‘nf_register_net_hook’ is declared in official kernel v6.1.X, at: https://github.com/torvalds/linux/blob/v6.1/include/linux/netfilter.h in your Kernel config you need to have CONFIG_NETFILTER.
