Documentation/networking/ is full of cryptically named files with driver documentation. This makes finding interesting information at a glance really hard. Move all those files into a directory called device_drivers (since not all drivers are for device) and fix up references. RFC v0.1 -> RFC v1: - also add .txt suffix to the files which are missing it (Quentin) Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Reviewed-by: Quentin Monnet <quentin.monnet@netronome.com> Acked-by: David Ahern <dsahern@gmail.com> Acked-by: Henrik Austad <henrik@austad.us> Signed-off-by: David S.

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.
