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,

In most cases the default value of 2 is a safe bet.
