The Gianfar Ethernet Driver
Sysfs File description
Author: Andy Fleming <afleming@freescale.com>
Updated: 2005-07-28
SYSFS
Several of the features of the gianfar driver are controlled
through sysfs files. 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.
CHECKSUM OFFLOADING
The eTSEC controller (first included in parts from late 2005 like
the 8548) has the ability to perform TCP, UDP, and IP checksums
in hardware. The Linux kernel only offloads the TCP and UDP
checksums (and always performs the pseudo header checksums), so
the driver only supports checksumming for TCP/IP and UDP/IP
packets. Use ethtool to enable or disable this feature for RX
and TX.
VLAN
In order to use VLAN, please consult Linux documentation on
configuring VLANs. The gianfar driver supports hardware insertion and
extraction of VLAN headers, but not filtering. Filtering will be
done by the kernel.
MULTICASTING
The gianfar driver supports using the group hash table on the
TSEC (and the extended hash table on the eTSEC) for multicast
filtering. On the eTSEC, the exact-match MAC registers are used
before the hash tables. See Linux documentation on how to join
multicast groups.
PADDING
The gianfar driver supports padding received frames with 2 bytes
to align the IP header to a 16-byte boundary, when supported by
hardware.
ETHTOOL
The gianfar driver supports the use of ethtool for many
configuration options. You must run ethtool only on currently
open interfaces. See ethtool documentation for details.

* Changes:
*
* 2003/05/01 - Tsippy Mendelson <tsippy.mendelson at intel dot com> and
* Amir Noam <amir.noam at intel dot com>
* - Added support for lacp_rate module param.
*
* 2003/05/01 - Shmulik Hen <shmulik.hen at intel dot com>
* - Based on discussion on mailing list, changed locking scheme
* to use lock/unlock or lock_bh/unlock_bh appropriately instead
* of lock_irqsave/unlock_irqrestore. The new scheme helps exposing
* hidden bugs and solves system hangs that occurred due to the fact
* that holding lock_irqsave doesn't prevent softirqs from running.
* This also increases total throughput since interrupts are not
* blocked on each transmitted packets or monitor timeout.
*
* 2003/05/01 - Shmulik Hen <shmulik.hen at intel dot com>
* - Renamed bond_3ad_link_status_changed() to
* bond_3ad_handle_link_change() for compatibility with TLB.
*
* 2003/05/20 - Amir Noam <amir.noam at intel dot com>
* - Fix long fail over time when releasing last slave of an active
* aggregator - send LACPDU on unbind of slave to tell partner this
* port is no longer aggregatable.
*
* 2003/06/25 - Tsippy Mendelson <tsippy.mendelson at intel dot com>
* - Send LACPDU as highest priority packet to further fix the above
* problem on very high Tx traffic load where packets may get dropped
* by the slave.
