[PATCH net 1/2] vsock/virtio: send a credit update when buffer size is changed

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

 



When the user application set a new buffer size value, we should
update the remote peer about this change, since it uses this
information to calculate the credit available.
