7 | SYSFS | ||
8 | |||
9 | Several of the features of the gianfar driver are controlled | ||
10 | through sysfs files. These are: | ||
11 | |||
12 | bd_stash: | ||
13 | To stash RX Buffer Descriptors in the L2, echo 'on' or '1' to | ||
14 | bd_stash, echo 'off' or '0' to disable | ||
15 | |||
16 | rx_stash_len: | ||
17 | To stash the first n bytes of the packet in L2, echo the number | ||
18 | of bytes to buf_stash_len. echo 0 to disable. | ||
19 | |||
20 | WARNING: You could really screw these up if you set them too low or high! | ||
21 | fifo_threshold: | ||
22 | To change the number of bytes the controller needs in the | ||
23 | fifo before it starts transmission, echo the number of bytes to | ||
24 | fifo_thresh. Range should be 0-511. | ||
25 | |||
26 | fifo_starve: | ||
27 | When the FIFO has less than this many bytes during a transmit, it | ||
28 | enters starve mode, and increases the priority of TX memory | ||
29 | transactions. To change, echo the number of bytes to | ||
30 | fifo_starve. Range should be 0-511. | ||
31 | |||
32 | fifo_starve_off: | ||
33 | Once in starve mode, the FIFO remains there until it has this | ||
34 | many bytes. To change, echo the number of bytes to | ||
35 | fifo_starve_off. Range should be 0-511. | ||
