* igb: Change to use statically allocated array for MSIx entriesCarolyn Wyborny2013-12-18
| | | | | | | | | | | This patch changes how the driver initializes MSIx and checks for MSIx configuration. This change makes it easier to reconfigure the device when queue changes happen at runtime using ethtool's set_channels feature.

* igb: Fix queue allocation method to accommodate changing during runtimeCarolyn Wyborny2013-12-18
| | | | | | | | | | | | | | When changing number of queues using ethtool's set_channels during runtime, a queue allocation could fail, which can leave the device in a down state. In order to preserve the usability of the device in this scenario, this patch changes the driver to allocate the number of queues only if they have not been allocated already. The first allocation is then done for the max number of queues, which is the default queues for this driver. With this change, queue quantity changes are not subject to queue allocation failures.

* ixgbe: Convert to use devm_hwmon_device_register_with_groupsGuenter Roeck2013-12-18
| | | | | | | | | | | | | | | | | | | | Simplify the code. Attach hwmon sysfs attributes to hwmon device instead of pci device. Avoid race conditions caused by attributes being created after hwmon device registration. Implicitly (through hwmon API) add mandatory 'name' sysfs attribute. Other cleanup: Instead of allocating memory for hwmon attributes, move attributes and all other hwmon related data into struct hwmon_buff and allocate the entire structure using devm_kzalloc. Check return value from calls to igb_add_hwmon_attr() one by one instead of logically combining them all together.

| * sfc: Allow filter removal only with exactly matching priorityBen Hutchings2013-12-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently a higher priority client can remove a lower priority client's filter with equal match-expression. This might happen if (a) the higher priority client has a double-free bug, or (b) another client with sufficient priority replaced and then removed an equal filter, allowing the low priority client to insert an equal filter. In neither case does it actually make sense to carry out the removal; we should say the filter doesn't exist, as the filter currently present is not the one that the high-priority client is referring to.

| | | | | | | | | | | | | | | | | | Change all the 'stack' naming to 'auto' (or other meaningful term); the device address list is based on more than just what the network stack wants, and the no-match filters aren't really what the stack wants at all.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MAC filters inserted automatically by the driver, based on the device address list (EF10) or no-match filters (Siena), should be overridable at MANUAL or REQUIRED priority. Currently they themselves have REQUIRED priority and this requires some odd special-casing. We also can't reliably tell whether such a MAC filter has or has not been overridden. We just remember that it is wanted by the stack (RX_STACK flag). Add another priority level, AUTO, between HINT and MANUAL, and use this for the automatic filters while they have not been overridden. Remove the RX_STACK flag. Add an RX_OVER_AUTO flag which is set only when an AUTO filter has been overridden (or was requested to be inserted while a higher-priority filter existed).
