ahh esqueci de comentar, um tcpdump no arquivo binário /var/log/pflog mostra
normalmente, mas nao em tempo real né,

eu ja fiz tcpdump normal direto no interface pflog0 e exibia os dados
completos

ja verifiquei no meu conf de kernel, está ativo normalmente as opções e
devices do PF de acordo com o handbook
