Rickard Strandqvist removes an unused function for i40e. John Linville reorders a piece of code so that y_budget does not get used by the FCoE code before it gets initialized. Mitch adds a delay after VF reset with a minimum of 10ms to allow the hardware internal FIFOs to flush. Bumps up the ARQ descriptors, since we can easily overrun the PF's admin receive queue. Added locking around the VF reset code, since during VF deallocation, we cannot depend on simply masking the interrupt since this does not lock out the service task, which can still call the reset routine. Fix a potential multi-minute delay on driver unload, VF disable or system shutdown. When the module is being unloaded, waiting for the PF to politely handle all of our admin queue requests might take forever with a lot of VFs enabled, so just stop everything and request a VF reset. Also stops the watchdog during shutdown to prevent a log full of admin queue errors and the occasional hang when the system is shut down. Anjali forces Tx descriptor writebacks on ITR by kicking off the SWINT interrupt since we noticed that there are non-cache-aligned Tx descriptors waiting in the ring while interrupts are disabled under NAPI. Enables loopback for the FCoE VSI, so that VSIs can directly talk to each other without going out on the wire. Matthew fixes an LED blink issue by making sure to clear the GPIO blink field, instead of OR'ing against zero if the field is already '1'. Greg cleans up a function header comment. Vasu helps biosdevname user tool to differentiate dev_port for PCoE netdev and PF netdev, by setting different dev_port value for FCoE netdev. Carolyn adds a call to u64_stats_init to the receive setup in order to avoid lockdep errors with seqcount on newer kernels. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the module is being unloaded, don't wait for the PF to politely handle all of our admin queue requests, as that might take forever with a lot of VFs enabled. Instead, just stop everything and request a VF reset. When the original shutdown code was written, VF resets were unreliable, so we avoided them. But with production hardware and firmware, and the 1.x PF driver, this is no longer the case. This fixes a potential multi-minute delay on driver unload, VF disable, or system shutdown.

| * i40e: add locking around VF resetMitch Williams2015-02-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During VF deallocation, we need to lock out the VF reset code. However, we cannot depend on simply masking the interrupt, as this does not lock out the service task, which can still call the reset routine. Instead, leave the interrupt enabled, but add locking around the VF disable and reset routines. For the disable code, we wait to get the lock, as the reset code will take a finite amount of time to run. For the reset code, we just return if we fail to get the lock. Since we know that the VFs are being disabled, we don't need to handle the reset. This fixes a panic when disabling SR-IOV.

Double the size of this queue, and increase the work limit to allow the PF to handle more requests in a single pass through the service task.

Upon fatal error, consumers of these interfaces (ULPs) that rely on completion of all their posted work-request could hang, thereby introducing dependencies in shutdown order. To prevent this from happening, we manage the relevant resources (CQs, QPs) that are used by the device. Upon a fatal error, we now generate simulated completions for outstanding WQEs that were not completed at the time the HW was reset. It includes invoking the completion event handler for all involved CQs so that the ULPs will poll those CQs. When polled we return simulated CQEs with IB_WC_WR_FLUSH_ERR return code enabling ULPs to clean up their resources and not wait forever for completions upon receiving remove_one. The above change requires an extra check in the data path to make sure that when device is in error state, the simulated CQEs will be returned and no further WQEs will be posted.

It relies on the new netlink API to collect data or perform actions (dumpit / doit). The main benefit of this compat layer is that it removes a lot of complex code from the tipc core as only the new API needs to be able harness data or perform actions. I.e. the compat layer isn't concerned with locking or how the internal data-structures look. As long as the new API stays relatively intact the compat layer should be fine. The main challenge in this compat layer is the randomness of the legacy API. Some commands send binary data and some send ASCII data, some are very picky in optimizing there buffer sizes and some just don't care. Most legacy commands put there data in a single TLV (data container) but some segment the data into multiple TLV's. This list of randomness goes on and on.. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

| * | tipc: convert legacy nl bearer enable/disable to nl compatRichard Alpe2015-02-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce a framework for transcoding legacy nl action into actions (.doit) calls from the new nl API. This is done by converting the incoming TLV data into netlink data with nested netlink attributes. Unfortunately due to the randomness of the legacy API we can't do this generically so each legacy netlink command requires a specific transcoding recipe. In this case for bearer enable and bearer disable. Convert TIPC_CMD_ENABLE_BEARER and TIPC_CMD_DISABLE_BEARER into doit compat calls.

| * | tipc: convert legacy nl bearer dump to nl compatRichard Alpe2015-02-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce a framework for dumping netlink data from the new netlink API and formatting it to the old legacy API format. This is done by looping the dump data and calling a format handler for each entity, in this case a bearer. We dump until either all data is dumped or we reach the limited buffer size of the legacy API. Remember, the legacy API doesn't scale. In this commit we convert TIPC_CMD_GET_BEARER_NAMES to use the compat layer.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | The new netlink API is no longer "v2" but rather the standard API and the legacy API is now "nl compat". We split them into separate start/stop and put them in different files in order to further distinguish them.

| | * | ath10k: prevent setting wrong key idx for stationSenthilKumar Jegadeesan2015-02-04

The reason for this behavior is that cached broadcast key is installed for station MAC address on association. After dot1x completes, unicast key is installed for station MAC address. Default key idx is set to broadcast key id when driver tries to send broadcast frame. This causes firmware to use broadcast key id to transmit unicast frames to stations. Used TX_USAGE flag to set default key for stations. Added callback for setting unicast default idx which will be invoked on every default key idx configuration.
