ntb: Add more debugfs support for ntb_perf testing options
The ntb_perf tool uses module parameters to control the
characteristics of its test. Enable the changing of these
options through debugfs, and eliminating the need to unload
and reload the module to make changes and run additional tests.
Add a new module parameter that forces the DMA channel
selection onto the same node as the NTB device (default: true).
- seg_order: Size of the NTB memory window; power of 2.
- run_order: Size of the data buffer; power of 2.
- use_dma: Use DMA or memcpy? Default: 0.
- on_node: Only use DMA channel(s) on the NTB node. Default: true.
