2012-01-04ethtool: Allow drivers to select RX NFC rule locationsBen Hutchings
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.

2011-12-16ethtool: Define and apply a default policy for RX flow hash indirectionBen Hutchings
All drivers that support modification of the RX flow hash indirection table initialise it in the same way: RX rings are assigned to table entries in rotation. Make that default policy explicit by having them call a ethtool_rxfh_indir_default() function. In the ethtool core, add support for a zero size value for ETHTOOL_SRXFHINDIR, which resets the table to this default.

2011-09-16ethtool: Update ethtool_rxnfc::rule_cnt on return from ETHTOOL_GRXCLSRLALLBen Hutchings
A user-space process must use ETHTOOL_GRXCLSRLCNT to find the number of classification rules, then allocate a buffer of the right size, then use ETHTOOL_GRXCLSRLALL to fill the buffer. If some other process inserts or deletes a rule between those two operations, the user buffer might turn out to be the wrong size. If it's too small, the return value will be -EMSGSIZE. But if it's too large, there is no indication of this. Fix this by updating the rule_cnt field on return. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.

2011-09-16ethtool: Explicitly state that RX NFC rule locations are prioritiesBen Hutchings
The location of an RX flow classification rule is needed to identify it for retrieval, replacement or deletion. However it also defines the priority of the rule in the case that a flow is matched by multiple rules. This is what I intended to imply by referring to the use of a TCAM, commonly used to implement that behaviour. However there are other ways this can be done, and it is better to specify this explicitly. Further, I want to add the option for automatic selection of rule locations.

2011-09-15net: consolidate and fix ethtool_ops->get_settings callingJiri Pirko
This patch does several things: - introduces __ethtool_get_settings which is called from ethtool code and from drivers as well. Put ASSERT_RTNL there. - dev_ethtool_get_settings() is replaced by __ethtool_get_settings() - changes calling in drivers so rtnl locking is respected. In iboe_get_rate was previously ->get_settings() called unlocked. This fixes it. Also prb_calc_retire_blk_tmo() in af_packet.c had the same problem. Also fixed by calling __dev_get_by_index() instead of dev_get_by_index() and holding rtnl_lock for both calls. - introduces rtnl_lock in bnx2fc_vport_create() and fcoe_vport_create() so bnx2fc_if_create() and fcoe_if_create() are called locked as they are from other places. - use __ethtool_get_settings() in bonding code Signed-off-by: Jiri Pirko <jpirko@redhat.com> v2->v3: -removed dev_ethtool_get_settings() -added ASSERT_RTNL into __ethtool_get_settings() -prb_calc_retire_blk_tmo - use __dev_get_by_index() and lock around it and __ethtool_get_settings() call v1->v2: add missing export_symbol Reviewed-by: Ben Hutchings <bhutchings@solarflare.com> [except FCoE bits] Acked-by: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: David S.

2011-08-16ethtool: Correct description of 'max_coalesced_frames' fieldsBen Hutchings
The current descriptions state that these fields specify 'How many packets to delay ... after a packet ...' which implies that the hardware should wait for (max_coalesced_frames + 1) completions before generating an interrupt. It is also stated that setting both this field and the corresponding 'coalesce_usecs' field to 0 is invalid. Together, this implies that the hardware must always be configured to delay a completion IRQ for at least 1 usec or 1 more completion. I believe that the addition of 1 is not intended, and David Miller confirms that the original implementation (in tg3) does not do this.

2011-06-30net: add external loopback test in ethtool self testAmit Kumar Salecha
External loopback test can be performed by application without any driver support on normal Ethernet cards. But on CNA devices, where multiple functions share same physical port. Here internal loopback test and external loopback test can be initiated by multiple functions at same time. To co exist all functions, firmware need to regulate what test can be run by which function. So before performing external loopback test, command need to send to firmware, which will quiescent other functions. User may not want to run external loopback test always. As special cable need to be connected for this test. So adding explicit flag in ethtool self test, which will specify interface to perform external loopback test.

2011-06-08v2 ethtool: remove support for ETHTOOL_GRXNTUPLEAlexander Duyck
This change is meant to remove all support for displaying an ntuple as strings via ETHTOOL_GRXNTUPLE. The reason for this change is due to the fact that multiple issues have been found including: - Multiple buffer overruns for strings being displayed. - Incorrect filters displayed, cleared filters with ring of -2 are displayed - Setting get_rx_ntuple displays no rules if defined. - Endianess wrong on displayed values. - Hard limit of 1024 filters makes display functionality extremely limited The only driver that had supported this interface was ixgbe. Since it no longer uses the interface and due to the issues mentioned above I am submitting this patch to remove it. v2: Updated based on comments from Ben Hutchings - Left ETH_SS_NTUPLE_FILTERS in code but commented on it being deprecated - Removed ethtool_rx_ntuple_list and ethtool_rx_ntuple_flow_spec_container - Left ETHTOOL_GRXNTUPLE but commented it as deprecated Also cleaned up set_rx_ntuple since there is no flow spec container to maintain we can drop all the code for the alloc and free of it and just return ops->set_rx_ntuple().

2011-04-29ethtool: Call ethtool's get/set_settings callbacks with cleaned dataDavid Decotigny
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.

2011-04-14ethtool: allow custom interval for physical identificationAllan, Bruce W
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.

2011-04-05ethtool: Change ETHTOOL_PHYS_ID implementation to allow dropping RTNLBen Hutchings
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>
