The function i40e_debug_aq() prints information helpful in debugging admin queue commands, but it doesn't do so correctly on big endian machines. This patch adds the appropriate LExx_TO_CPU wrappers for big endian architectures. Also update the copyright year. Change-ID: I4b2dc229ed5bf6dfe35632a58cddf53c21aff4b0 Signed-off-by:

The Churn Detection machines detect the situation where a port is operable, but the Actor and Partner have not attached the link to an Aggregator and brought the link into operation within a bound time period. Under normal operation of the LACP, agreement between Actor and Partner should be reached very rapidly. Continued failure to reach agreement can be symptomatic of device failure.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-02-23 This series contains updates to e1000e, igbvf, i40e and i40evf. David adds support for i219 devices to the e1000e driver. Jeff (me) provides two patches to cleanup igbvf, first cleans up the whitespace issues found and the second cleans up the usage of msleep(), min() and max() with usleep_range(), min_t() and max_t() respectively. Kamil updates the shadow RAM read/write functions by refactoring them to prepare for future work. Shannon renames the debugfs command "clear_stats pf" to clear_stats port" to clarify what the function really does. Mitch refactors the receive routine, by splitting the receive hot path code into two, one for packet split and one for single buffer, which improves receive performance. Disables NAPI polling sooner when closing the interface to fix an occasional panic during close which was caused by the driver trying to delete and clean rings at the same time. Also refactors reset for i40evf, since a recent change to the shutdown flow messed up the reset flow. Since i40evf_down() now holds the critical section lock, we cannot call it from the reset handler, which also holds the lock. Nicholas restricts the virtual channel opcodes should remain consistent between updates to the opcode enum. Neerav converts the VSI connection type to use a #define instead of using a magic number. Anjali updates the registers file to remove registers no longer available. Also fixes the EMPR interrupt handling, so that we won't trigger another EMPR when we receive an EMPR event. Catherine cleans up the variable an_enable since it was set and never used. Greg fixes the netdev op that allows the operator to turn MAC/VLAN spoof checking on and off so that it includes the flag for VLAN spoof checking. v2: Updated patch #10 in the series to use test_and_clear_bit() as suggested by Sergei Shtylyov ==================== Signed-off-by: -

Under rare circumstances, after a reset, set_rx_mode might get called while the watchdog is running, which will cause a deadlock on the critical section lock. To correct this, add a counter and give up trying to get the lock after fifty tries. Log a message if this happens but don't take any other action. Because this happens after a reset, all of the Rx filters are still in place and the device won't lose connectivity. We can also get stuck during shutdown, if the PF has stopped communicating with us, or if a reset is occurring. If we can't get the lock after a reasonable amount of time, just error out. Something else bad is happening anyway, so adding this filter is the least of our concern right now. Change-ID: I159731e2a82a06b389ee31b34ce336548e05baa0 Signed-off-by:

A recent change to the shutdown flow messed up the reset flow. Since i40evf_down now holds the critical section lock, we cannot call it from the reset handler, which also holds the lock. To do so causes a deadlock accompanied by wailing and gnashing of teeth. This is easily triggered by running an ethtool self-test on the PF device. Instead, we move the relevant portions of i40evf_down into the reset handler and bend them to our will. Additionally, we can optimize the reinit path by not deleting the MAC and VLAN filters and then adding them back again. Instead, we just set the 'add' flag and let the watchdog resynchronize the filter list with the PF driver. We also reword a few messages to make them more consistent with the rest of the driver.

Until the time a more robust versioning scheme is needed/implemented all established virtual channel opcode values should remain consistent between updates to the opcode enum. This patch repositions I40E_VIRTCHNL_OP_CONFIG_RSS to the end of the enum. In its current position this opcode displaces the initial value of I40E_VIRTCHNL_OP_EVENT and will cause PF/VF compatibility issues. Going forward the expectation is either: a) All future opcode additions will be added as the last element of the enum. Once VF drivers start making use of the new commands the virtual channel version will need to be incremented and drivers will need to implement a simple version check whereby VF drivers can only load on PFs with a >= version. b) or, if needed, design and implement a more complicated API negotiation capability. In either case PF drivers should always maintain backwards compatibility with earlier VF driver versions. Change-ID: Ie245daa09a231b6680ed793d648bdcc76caefe58 Signed-off-by:

Split the receive hot path code into two, one for packet split and one for single buffer. This improves receive performance since we only need to check if the ring is in packet split mode once per NAPI poll time, not several times per packet. The single buffer code is further improved by the removal of a bunch of code and several variables that are not needed. On a receive-oriented test this can improve single-threaded throughput. Also refactor the packet split receive path to use a fixed buffer for headers, like ixgbe does. This vastly reduces the number of DMA mappings and unmappings we need to do, allowing for much better performance in the presence of an IOMMU. Lastly, correct packet split descriptor types now that we are actually using them. Change-ID: I3a194a93af3d2c31e77ff17644ac7376da6f3e4b Signed-off-by:

Sathya Perla says: ==================== be2net: patch set Hi Dave, the following patch set reduces code duplication in probe/pci-resume/eeh-resume and remove/pci-suspend/eeh-error and UE-error detect/recovery paths. New helper routines have been introduced for this purpose. Pls apply this set to the net-next tree. Thanks! Patch 1 refactors the alloc/free code of adapter struct's fields into a new set of helper routines -- be_drv_init/cleanup(). Patch 2 gets rid of the be_get_initial_config() routine as be_get_config() is the place holder for related code. Patch 3 introduces a new helper routine be_func_init() to execute the initialization code used in probe/pci-resume/eeh-resume to remove code duplication. Patch 4 introduces a wrapper for scheduling/canceling error detection task on similar lines to the be_worker task. Patch 5 refactors UE error detection and recovery code on similar lines to EEH code. Cleaning up resources is done in the error detection routine followed by error recovery. Patch 6 gets rid of the lancer_test_and_set_rdy_state() routine as the same code now available in be_func_init(). Patch 7 creates a new helper routine be_resume() for all the common code in be_probe(), be_pci_resume() and be_eeh_resume(), to reduce code duplication. Patch 8 creates a new helper routine be_cleanup() for all the common cleanup code duplicated in the suspend/EEH err detection paths. Patch 9 moves be_func_init() inside be_setup() as everytime be_setup() is called, the driver will have to wait for the function/FW to be be initialized. ==================== Signed-off-by:
