Struct UsedBuffer 

pub struct UsedBuffer {
    pub id: u16,
    pub len: u32,
}

A buffer returned from the ring after being used by the device.

When the device completes processing a buffer chain, it returns this structure containing the original descriptor ID and the number of bytes written (for chains with writable buffers).

Fields

id: u16

Descriptor ID that was assigned when the buffer was submitted

len: u32

Number of bytes written by the device to writable buffers. For read-only chains, this may be 0 or the total readable length.
