ethtool: Extend the ethtool API to obtain plugin module eeprom data

2012-05-10T01:22:17+00:00

ETHTOOL_GMODULEINFO returns a new struct ethtool_modinfo that will return the
type and size of plug-in module eeprom (such as SFP+) for parsing
by userland program.

ETHTOOL_GMODULEEEPROM returns the raw eeprom information
using the existing ethtool_eeprom structture to return the data

ethtool: Split ethtool_get_eeprom() to allow for additional EEPROM accessors

2012-05-10T01:22:17+00:00

We want to support reading module (SFP+, XFP, ...) EEPROMs as well as
NIC EEPROMs.  They will need a different command number and driver
operation, but the structure and arguments will be the same and so we
can share most of the code here.

ethtool: Add a common function for drivers with transmit time stamping.

2012-04-04T09:28:46+00:00

Currently, most drivers do not support transmit SO_TIMESTAMPING. For those
that do support it, there is one appropriate response to the get_ts_info
query. This patch adds a common function providing this response.

ethtool: Introduce a method for getting time stamping capabilities.

2012-04-04T09:28:45+00:00

This commit adds a new ethtool ioctl that exposes the SO_TIMESTAMPING
capabilities of a network interface. In addition, user space programs
can use this ioctl to discover the PTP Hardware Clock (PHC) device
associated with the interface.

Since software receive time stamps are handled by the stack, the generic
ethtool code can answer the query correctly in case the MAC or PHY
drivers lack special time stamping features.

net: Support RX-ALL feature flag.

2012-02-24T09:42:07+00:00

This flag requests that network devices pass all
received frames up the stack, even ones with errors
such as invalid FCS (frame check sum).  This will
allow sniffers to see bad packets and perhaps
give the user some idea how to fix the problem.

net: Support RXFCS feature flag.

2012-02-24T09:19:59+00:00

When set on hardware that supports the feature,
this causes the Ethernet FCS to be appended
to the end of the skb.

Useful for sniffing packets.

ethtool: Null-terminate filename passed to ethtool_ops::flash_device

2012-02-01T19:47:17+00:00

The parameters for ETHTOOL_FLASHDEV include a filename, which ought to
be null-terminated.  Currently the only driver that implements
ethtool_ops::flash_device attempts to add a null terminator if
necessary, but does it wrongly.  Do it in the ethtool core instead.

ethtool: allow ETHTOOL_GSSET_INFO for users

2012-01-23T04:41:05+00:00

Allow ETHTOOL_GSSET_INFO ethtool ioctl() for unprivileged users.
ETHTOOL_GSTRINGS is already allowed, but is unusable without this one.

ethtool: Allow drivers to select RX NFC rule locations

2012-01-04T19:09:10+00:00

Define special location values for RX NFC that request the driver to
select the actual rule location.  This allows for implementation on
devices that use hash-based filter lookup, whereas currently the API is
more suited to devices with TCAM lookup or linear search.

In ethtool_set_rxnfc() and the compat wrapper ethtool_ioctl(), copy
the structure back to user-space after insertion so that the actual
location is returned.
