2014-12-06i40e: increase ARQ sizeMitch Williams1-1/+1
The ARQ needs to have at least as many entries as VFs, or the VFs will get errors from the FW when they send messages to the PF. Since we don't know how many VFs we'll end up with, just set up 128 descriptors.

2014-11-18i40e: Modify Tx disable wait flow in case of DCB reconfigurationNeerav Parikh1-0/+1
When DCB TC configuration changes the firmware suspends the port's Tx. Now, as DCB TCs may have changed the PF driver tries to reconfigure the TC configuration of the VSIs it manages. As part of this process it disables the VSI queues but the Tx queue disable will not complete as the port's Tx has been suspended. So, waiting for Tx queues to go to disable state in this flow may lead to detection of Tx queue disable timeout errors. Hence, this patch adds a new PF state so that if a port's Tx is in suspended state the Tx queue disable flow would just put the request for the queue to be disabled and return without waiting for the queue to be actually disabled. Once the VSI(s) TC reconfiguration has been done and driver has called firmware AQC "Resume PF Traffic" the driver checks the Tx queues requested to be disabled are actually disabled before re-enabling them again.

2014-11-11i40e: don't do link_status or stats collection on every ARQShannon Nelson1-1/+2
The ARQ events cause a service_task execution, and we do a link_status check and full stats gathering for each service_task. However, when there are a lot of ARQ events, such as when doing an NVM update, we end up doing 10's if not 100's of these per second, thereby heavily abusing the PCI bus and especially the Firmware. This patch adds a check to keep the service_task from running these periodic tasks more than once per second, while still allowing quick action to service the events.

2014-09-04i40e: Fix an issue when PF reset failsAnjali Singhai Jain1-0/+1

2014-08-27i40e/i40evf: Ignore a driver perceived Tx hang if the number of desc pending < 4Anjali Singhai Jain1-0/+1
We are seeing situations where the driver sees a hang with less than 4 desc pending, if the driver chooses to ignore it the queue progresses forward and the stack never experiences a real hang. With this patch we will log a stat when this situation happens "tx_sluggish" will increment and we can see some more details at a higher debug level. Other than that we will ignore this particular case of Tx hang.

2014-08-27i40e: Add a FD flush counter to ethtoolAnjali Singhai Jain1-0/+1
This helps know how many times the interface had to flush and replay FD filter table, which gives an indication on how often we are getting FD table full situation. Also check on certain pf states before proceeding to add or delete filters since we can't add or delete filters if we are in those states.

2014-08-26i40e: ATR policy change to flush the table to clean stale ATR rulesAnjali Singhai Jain1-0/+6
Instead of disabling ATR when we get a programming error, we now will wait it out to see if some room gets created by ATR rule deletion. If we still have too many errors and ATR filter count did not change much, its time to flush and replay. We no more auto-disable ATR when we have errors in programming. The disabling of ATR when we get programming error was buggy and was still adding new rules and causing continuous errors. With this policy change we flush instead when we see too many errors. ATR is still disabled if we add a SB rule for TCP/IPv4 flow type, more logic is added to re-enable it once all SB TCP/IPv4 rules are gone.

2014-07-16i40e: Add ndo_get_phys_port_id() callback supportNeerav Parikh1-0/+1
This patch adds a new API to get the port mac address from firmware. It also adds support to the ndo_get_phys_port_id() callback to provide port specific unique id to the netdev layer. If the adapter has a valid per-port mac address then that would be used for this purpose and is expected to be unique on a per-port basis. The information can be viewed by reading the phys_port_id attribute in sysfs for each netdev or via IF netlink interface.

2014-06-26i40e: Fix the FD sideband logic to detect a FD table full conditionAnjali Singhai Jain1-1/+2
Hardware does not have a way of telling a PF how much of the global shared FD table space is still available or is consumed. Previously, every PF but PF0 would think there was still space available when there wasn't. The PFs would continue to try to add filters and fail. With this new logic if a filter programming error is detected we just check if we are close to the guaranteed space full and that can be used as a hint to say, there might not be space and we should turn off the features. This way we can turn off the feature in SW for all PFs in time.

To allow for this, we allocate space for a larger number of VSIs than is guaranteed by the firmware, with the knowledge that we may fail to get them all in the future. Note that we are just allocating pointers here, the actual (much larger) VSI structures are allocated on demand.

All other VSIs are only enabled for the default traffic class settings for now. The driver registers and listens to firmware events that may require change in the DCB settings. It may reconfigure the VSI settings based on these events. This patch exposes IEEE DCBNL interfaces for the i40e driver to allow any application to query the DCB settings on the adapter.

2014-01-09i40e: Fix GPL headerGreg Rose1-4/+3
The GPL header included in each file in the i40e driver doesn't need to include the "this program" text since this driver is already part of the larger kernel.

2014-01-05i40e: Fix ring allocationNeerav Parikh1-3/+0
The allocation and clearing of rings for a VSI should be using the alloc_queue_pairs and not num_queue_pairs. The alloc_queue_pairs per VSI is a pre-allocated number of queues assigned to a VSI; based on number of TCs enabled only certain number of queues may be used from that. This is mainly valid only for the LAN VSI case as that is the only VSI that may be enabled with multiple traffic classes. In the future the number of TCs may change based on DCBX configuration. The actual number of queues that are enabled/configured is based on the number of TCs enabled for a given VSI and that is stored in num_queue_pairs. With this change num_[tr]x_queues is unused so remove them.

2014-01-03i40e: refactor VF reset flowMitch Williams1-0/+1
Fix the VF reset flow so that it works on real hardware. After discussions with the HW team, the reset flow has been changed somewhat. - Change the i40e_reset_vf function to a void type, and fix up the callers to reflect this. - Move the MSI-X disable code to i40e_free_vf_res since it must be done every time the VF is freed, regardless of whether or not it is reset. - Ensure that the PCIe bus is quiet before polling the reset bit. - Don't clear the VFGEN_RSTAT1 register at the beginning as it is cleared by the reset. - Poll longer for the reset to be done. - Disable the queues using an existing function rather than rolling our own. - Free and reallocate the VSI after reset to avoid rx hang.

2014-01-03i40e: Rx checksum offload for VXLANJoseph Gasparakis1-0/+1

2014-01-03i40e: add wake-on-lan supportShannon Nelson1-0/+1
Wake on LAN is disabled by default and will remain that way for most platforms, but there is an NVM setting that allows vendors to enable it for a port if they think they've provided the right power environment for the device. This patch adds code to check the NVM setting and enable Magic Packet use if WoL is enabled for the port. Since only Magic Packet is supported, there's not a lot of HW configuration needed.
