| help |
| Number of buffers available for fragments of TX buffers. Warning: |
| setting this to 0 means that the application must ensure that |
| queued TX buffers never need to be fragmented, i.e. that the |
| controller's buffer size is large enough. If this is not ensured, |
| and there are no dedicated fragment buffers, a deadlock may occur. |
| In most cases the default value of 2 is a safe bet. |
