This is minor information leakage as packet socket is\nnamespace aware.\n\nAdd a net pointer in `packet_type` to keep the net namespace of\nof corresponding packet socket. In `ptype_seq_show`, this net pointer\nmust be checked when it is not NULL."

Esta es una fuga de informaci\u00f3n menor ya que el socket del paquete reconoce el espacio de nombres. Agregue un puntero de red en `packet_type` para mantener el espacio de nombres de red del socket de paquete correspondiente. En `ptype_seq_show`, este puntero de red debe verificarse cuando no sea NULL."
