También proporcionó un reproductor limpio. El problema se reduce a 'mptcp_frag_can_collapse_to()' suponiendo que sólo MPTCP utilizará el page_frag dado. Si otros (por ejemplo, el protocolo TCP simple) asignan fragmentos de página, podemos terminar reutilizando la memoria ya asignada para mptcp_data_frag.
