...responses with VIRTIO_VSOCK_OP_ATTACH to client Virtio VM socket credit update: Virtio VM socket uses credit-based flow control. The sender maintains tx_cnt which counts the totoal number of bytes it has sent out, peer_fwd_cnt which counts the totoal number of byes the receiver has forwarded, and peer_buf_alloc which is the size of the receiver's receive buffer. The sender can send no more than the credit the receiver gives to the sender: credit = peer_buf_alloc - (tx_cnt - peer_fwd_cnt).
