We try for new code to avoid reverse Christmas tree ;)

->

+       struct tc_action_net *tn = net_generic(net, tunnel_key_net_id);
+       struct nlattr *tb[TCA_TUNNEL_KEY_MAX + 1];
+       struct tcf_tunnel_key_params *params_old;
+       struct tcf_tunnel_key_params *params_new;
+       struct metadata_dst *metadata = NULL;
+       struct tc_tunnel_key *parm;
+       struct tcf_tunnel_key *t;
+       bool exists = false;
+       __be64 key_id;
+       int ret = 0;
+       int err;


Other than this, code looks fine to me, thanks.
