* | i40e/i40evf: fix unicast mac address addShannon Nelson2015-10-071-23/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using something like "ip maddr add ..." to add another unicast mac address to the netdev, the mac address comes into the set_rx_mode handler in the multicast list whether it is a unicast or multicast address. This was confusing the code when it was trying to search for addresses that needed to be deleted from the VSI, because it was looking for the VSI unicast address in the netdev unicast list. The result was that a new unicast address would get added to the VSI list and then immediately removed, and would never actually make it down into the hardware. This patch removes the separation from unicast and multicast in the search for filters to be deleted. It also simplifies the logic a little with a jump to the bottom of the loop when an address is found. Now it doesn't matter which netdev list the address is hiding in, we'll check them all.

* | i40e/i40evf: give up the __func__Shannon Nelson2015-10-072-38/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | During early development, we added the function name to all of the error strings to make debugging simpler. Now that we've released the driver, our users should have more comprehensible error messages. So tear the roof off and give up the __func__. Ow.

* | i40e/i40evf: assure clean asq status reportShannon Nelson2015-10-071-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | There was a possibility where the asq_last_status could get through without update and thus report a previous error. I don't think we've actually seen this happen, but this patch will help make sure it doesn't.

* | i40evf: don't blow away MAC addressMitch Williams2015-10-031-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Under certain circumstances, we can get an extra VF_RESOURCES message from the PF driver at runtime. When this happens, we need to parse it because our VSI may have changed out from underneath us, and that will affect our relationship with the PF driver. However, parsing the resources message also blows away our current MAC address in the hardware struct, usually with all zeros. When this happens, the next time the interface is opened, it will have no MAC address and will a) not work and b) complain. Fix this issue by restoring the current MAC address from the netdev struct after we parse the resource message.

Vasily Averin provides a couple of rtnl lock/unlock fixes for both i40e and i40evf. Shannon provides several updates and fixes, first fixes up a type clash in i40e_aq_rc_to_posix(), where the error codes are signed values, so we need to treat them as such. Then fixes up a padding issue where an extra byte is added in i40e_aqc_get_cee_dcb_cfg_v1_resp to directly acknowledge the padding. Updated i40e to keep debugfs register read and writes from accessing outside of the io-remapped space. Added support and device id for another 20 GbE device. Jesse fixes the transmit hand workaround code for ARM that was causing Tx hangs to still occur occasionally when there really was no hang. Then fixed the receive dropped counter to show up in netstat interface. Refactor the interrupt enable function since it was always making the caller add the base_vector from the VSI struct which is already passed to the function. Fix kbuild warnings found in 0day build infrastructure by adding a harmless cast to a dev_info(), also fix 32 bit build warnings found by sparse. Greg fixed a configuration error that results if a port VLAN is set for a VF before the VF driver is loaded, so that when the VF driver is loaded the port VLAN is ignored. Mitch fixes the use of QOS field consistently in i40e_ndo_set_vf_port_vlan(). Modified the init timing of the driver to increase stability on load/unload and SR-IOV enable/disable cycles. Anjali updates i40e to not collect VEB stats if they are disabled in the hardware for performance reasons. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
| * | i40evf: tweak init timingMitch Williams2015-09-301-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch tweaks the init timing of the driver just a little bit to increase stability on load/unload and SR-IOV enable/disable cycles. First, run the init_task loop a little quicker in order to reduce overall init time. Second, stagger the start of the init task based on the device's PCIe function ID. This lessens the impact on the firmware when a whole bunch of VFs are initialized simultaneously, e.g. enabling SR-IOV without the VF driver blacklisted. For single VFs assigned to VMs this will have no effect as the function ID will always be 0.

It was running when it didn't need to, and not clearing the ring->arm_wb state after it was set. This caused Tx hangs to still occur occasionally when there really was no hang. Fix this by resetting the variable right after it was used.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch modifies the driver timeout logic by issuing a writeback request via a software interrupt to the hardware the first time the driver detects a hang. The driver was too aggressive in resetting a hung queue, so back that off by removing logic to down the netdevice after too many hangs, and move the function to the service task.

| | | | | | | | | | | | Store off the PF's API version, then use it to determine whether or not to send it our capabilities. Change the version checking to allow for PF drivers with lower API versions than our current version, so we can still talk to PF drivers over the 1.0 API.

* i40evf: handle big resetsMitch Williams2015-07-233-46/+95
| | | | | | | | | | | | | | | | | | | | | | | | The most common type of reset that the VF will encounter is a PF reset that cascades down into a VF reset for each VF. In this case, the VF will always be assigned the same VSI and recovery is fairly simple. However, in the case of 'bigger' resets, such as a Core or EMP reset, when the device is reinitialized, it's probable that the VF will NOT get the same VSI. When this happens, the VF will not be able to recover, as it will continue to request resources for its original VSI. Add an extra state to the admin queue state machine so that the driver can re-request its configuration information at runtime. During reset recovery, set this bit in the aq_required field, and fetch the (possibly new) configuration information before attempting to bring the driver back up. Since the driver doesn't know what kind of reset it has encountered, this step is done even for a PF reset, but it doesn't hurt anything - it just gets the same VSI back.

* i40e: add VF capabilities to virtual channel interfaceMitch Williams2015-07-231-5/+11
| | | | | | | | | | | | | | | | | | | | | To prepare for the changes coming up in the X722 device and future devices, the virtual channel interface has to change slightly. The VF driver can now report what its capable of supporting, which then informs the PF driver when it sends the configuration information back to the VF. A 1.1 VF driver on a 1.0 PF driver should not send its capabilities. Likewise, a 1.1 PF driver controlling a 1.0 VF driver should not expect or depend upon receiving the VF capabilities. All other aspects of the API are unchanged.

| | | | | | | | | | | | | | | | This patch changes the switch statement for dynamic interrupt throttling and adds a default case. With this patch, we check the latency setting instead of the current ITR settings and the included refactor improves performance. Without this patch, the ITR setting would never change dynamically, and there was no default.

For PBLE resource management, it is more efficient for it to manage its backing pages. For VF, PBLE backing page addresses will be send to PF driver for PBLE resource. The i40e_remove_pd_bp() is also modified to not free pre-allocated pages and free only ones which were allocated in i40e_add_pd_table_entry().

| | | | | | | | | | | | | During close, all of the MAC filters are cleared, so the driver would be unable to receive unicast packets after being closed and reopened. Add the adapter's "hardware" MAC address filter in open, not init. This ensures that the correct filter is present each time.

* i40evf: don't delete all the filtersMitch Williams2015-07-141-1/+3
| | | | | | | | | | | | | | | | | Due to an inverted conditional, the driver was marking all of its MAC filters for deletion every time set_rx_mode was called. Depending upon the timing of the calls to set_rx_mode and the processing of the admin queue, the driver would (accidentally) end up with a varying number of functional filters. Correct this logic so that MAC filters are added and removed correctly. Add a check for the driver's "hardware" MAC address so that this filter doesn't get removed incorrectly.

| | | | | | | | | | | | | The driver currently only maps TX and RX queues to a single MSI-X vector per queue pair if there are exactly enough vectors for this. Unfortunately, if we have too many vectors it will fail and allocate queues to vectors in a suboptimal manner. Change the condition check to allow for excess vectors. In this case, the extras just won't be used.
