* ethtool: Added support for FW dumpAnirban Chakraborty2011-05-13
| | | | | | | | | | | | | | | | | | | | | Added code to take FW dump via ethtool. Dump level can be controlled via setting the dump flag. A get function is provided to query the current setting of the dump flag. Dump data is obtained from the driver via a separate get function. Changes from v3: Fixed buffer length issue in ethtool_get_dump_data function. Updated kernel doc for ethtool_dump struct and get_dump_flag function. Changes from v2: Provided separate commands for get flag and data. Check for minimum of the two buffer length obtained via ethtool and driver and use that for dump buffer Pass up the driver return error codes up to the caller. Added kernel doc comments.

* ethtool: Call ethtool's get/set_settings callbacks with cleaned dataDavid Decotigny2011-04-29
| | | | | | | | | | | | | | | | | | | | | This makes sure that when a driver calls the ethtool's get/set_settings() callback of another driver, the data passed to it is clean. This guarantees that speed_hi will be zeroed correctly if the called callback doesn't explicitely set it: we are sure we don't get a corrupted speed from the underlying driver. We also take care of setting the cmd field appropriately (ETHTOOL_GSET/SSET). This applies to dev_ethtool_get_settings(), which now makes sure it sets up that ethtool command parameter correctly before passing it to drivers. This also means that whoever calls dev_ethtool_get_settings() does not have to clean the ethtool command parameter. This function also becomes an exported symbol instead of an inline. All drivers visible to make allyesconfig under x86_64 have been updated. Signed-off-by: David Decotigny <decot@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* ethtool: allow custom interval for physical identificationAllan, Bruce W2011-04-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When physical identification of an adapter is done by toggling the mechanism on and off through software utilizing the set_phys_id operation, it is done with a fixed duration for both on and off states. Some drivers may want to set a custom duration for the on/off intervals. This patch changes the API so the return code from the driver's entry point when it is called with ETHTOOL_ID_ACTIVE can specify the frequency at which to cycle the on/off states, and updates the drivers that have already been converted to use the new set_phys_id and use the synchronous method for identifying an adapter. The physical identification frequency set in the updated drivers is based on how it was done prior to the introduction of set_phys_id. Compile tested only. Also fixes a compiler warning in sfc. v2: drivers do not return -EINVAL for ETHOOL_ID_ACTIVE v3: fold patchset into single patch and cleanup per Ben's feedback Signed-off-by: Bruce Allan <bruce.w.allan@intel.com> Cc: Ben Hutchings <bhutchings@solarflare.com> Cc: Sathya Perla <sathya.perla@emulex.com> Cc: Subbu Seetharaman <subbu.seetharaman@emulex.com> Cc: Ajit Khaparde <ajit.khaparde@emulex.com> Cc: Michael Chan <mchan@broadcom.com> Cc: Eilon Greenstein <eilong@broadcom.com> Cc: Divy Le Ray <divy@chelsio.com> Cc: Don Fry <pcnet32@frontier.com> Cc: Jon Mason <jdmason@kudzu.us> Cc: Solarflare linux maintainers <linux-net-drivers@solarflare.com> Cc: Steve Hodgson <shodgson@solarflare.com> Cc: Stephen Hemminger <shemminger@linux-foundation.org> Cc: Matt Carlson <mcarlson@broadcom.com> Acked-by: Jon Mason <jdmason@kudzu.us> Acked-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.

* | ethtool: Change ETHTOOL_PHYS_ID implementation to allow dropping RTNLBen Hutchings2011-04-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ethtool ETHTOOL_PHYS_ID command runs for an arbitrarily long period of time, holding the RTNL lock. This blocks routing updates, device enumeration, and various important operations that one might want to keep running while hunting for the flashing LED. We need to drop the RTNL lock during this operation, but currently the core implementation is a thin wrapper around a driver operation and drivers may well depend upon holding the lock. Define a new driver operation 'set_phys_id' with an argument that sets the ID indicator on/off/inactive/active (the last optional, for any driver or firmware that prefers to handle blinking asynchronously). When this is defined, the ethtool core drops the lock while waiting and only acquires it around calls to this operation. Deprecate the 'phys_id' operation in favour of this. It can be removed once all in-tree drivers are converted. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

Since user-space may still be using the old structure definition for the ETHTOOL_{G,S}RXFH commands, and since they do not need the additional fields, only copy the originally defined fields to and from user-space.
