These are: - -bd_stash: -To stash RX Buffer Descriptors in the L2, echo 'on' or '1' to -bd_stash, echo 'off' or '0' to disable - -rx_stash_len: -To stash the first n bytes of the packet in L2, echo the number -of bytes to buf_stash_len. echo 0 to disable. - -WARNING: You could really screw these up if you set them too low or high! -fifo_threshold: -To change the number of bytes the controller needs in the -fifo before it starts transmission, echo the number of bytes to -fifo_thresh. Range should be 0-511. - -fifo_starve: -When the FIFO has less than this many bytes during a transmit, it -enters starve mode, and increases the priority of TX memory -transactions. To change, echo the number of bytes to -fifo_starve. Range should be 0-511. - -fifo_starve_off: -Once in starve mode, the FIFO remains there until it has this -many bytes. To change, echo the number of bytes to -fifo_starve_off. Range should be 0-511.
