[PATCH net v2 1/2] vhost/vsock: fix packet delivery order to monitoring devices

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



We want to deliver packets to monitoring devices before it is
put in the virtqueue, to avoid that replies can appear in the
packet capture before the transmitted packet.
