2014-06-11i40e/i40evf: Add Flow director stats to PF statsAnjali Singhai Jain
Add members to stat struct to keep track of Flow director ATR and SideBand filter packet matches. Change-ID: Ibbb31a53c7adcc2bb96991dd80565442a2f2513c Signed-off-by: Anjali Singhai Jain <anjali.singhai@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
2014-06-11i40e: Separate out DCB capability and enabled flagsNeerav Parikh
Currently if the firmware reports DCB capability the driver enables I40E_FLAG_DCB_ENABLED flag. When this flag is enabled the driver inserts a tag when transmitting a packet from the port even if there are no DCB traffic classes configured at the port. This patch adds a new flag I40E_FLAG_DCB_CAPABLE that will be set when the DCB capability is present and the existing flag I40E_FLAG_DCB_ENABLED will be set only if there are more than one traffic classes configured at the port.

2014-06-11i40e: Change the notion of src and dst for FD_SB in ethtoolAnjali Singhai Jain
In XL710 devices we program FD filter's fields from Tx perspective of the flow. However the user interface exposed in ethtool should be compliant with the previous generation of drivers where a filter src and dst field are from the RX perspective. This patch changes the ethtool interface in this regard to match the other drivers.

2014-06-08i40e: allow for more VSIsMitch Williams
The number of VSIs that the firmware reports to us is a guaranteed minimum, not an absolute maximum. The hardware actually supports far more than the reported value, which we often need. 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.

This patch removes the unnecessary ptp_tx_work item. It conflicts with the interrupt-based handler, and will cause spurious warning messages to be displayed in the kernel log.

2014-03-28i40e: eeprom integrity check on load and emprShannon Nelson
The driver needs to verify the eeprom checksum and firmware crc status bits, and shutdown the driver if they fail. This code stops the processing of traffic, but doesn't kill the PF netdev so that the NVMUpdate process should still have a chance at fixing the image. The eeprom is checked on driver load and after an EMP reset, the latter of which should be generated after an NVMUpdate.

2014-01-17i40e: add DCB and DCBNL supportNeerav Parikh
This patch adds capability to configure DCB on i40e network interfaces using Intel XL710 adapter firmware APIs. By default all VSIs are only enabled for the default traffic class enabled by firmware for any given PF. The driver would query the firmware for the traffic classes that are enabled for the port and reconfigure the LAN VSI to match to the port traffic class settings. 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.

2014-01-05i40e: Fix ring allocationNeerav Parikh
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.

2013-10-09i40e: Move rings from pointer to array to array of pointersAlexander Duyck
Allocate the queue pairs individually instead of as a group. This allows for much easier queue management as it is possible to dynamically resize the queues without having to free and allocate the entire block. Ease statistic collection by treating Tx/Rx queue pairs as a single unit. Each pair is allocated together and starts with a Tx queue and ends with an Rx queue. By ordering them this way it is possible to know the Rx offset based on a pointer to the Tx queue.

2013-10-09i40e: Move q_vectors from pointer to array to array of pointersAlexander Duyck
Allocate the q_vectors individually. The advantage to this is that it allows for easier freeing and allocation. In addition it makes it so that we could do node specific allocations at some point in the future.
