Usually udp_sock_handler() will receive and forward multiple (up to 32) datagrams in udp_sock_handler(), then forward them all to the tap interface. However, when in pasta mode we will only receive and forward a single datagram at a time. Change it to receive multiple datagrams at once, like the other paths.
