2015-02-26i40e: stop flow director on shutdownMitch A Williams
In some cases, the hardware would continue to try to access the FDIR ring after entering D3Hot state, which would cause either PCIe errors or NMIs, depending upon system configuration. Explicitly stop FDIR in our shutdown routine to eliminate this possibility.

2015-02-26i40e: disconnect irqs on shutdownShannon Nelson
Combine the ICR0 shutdown with the standard interrupt shutdown, and add the interrupt clearing to the PCI shutdown path. This prevents the driver from allowing stray interrupts or causing system logs from un-handled interrupts.

This will fix a warning with multiple function mode where systems regularly have more cores than vectors. Also add extra comment for readability.

2015-01-16i40e: Support for NPAR iSCSI partition with DCBNeerav Parikh
Add parsing and reporting of iSCSI capability for a given device or function. Also add support for iSCSI partition type with DCB in NPAR mode. In this mode it is expected that software would configure both the LAN and iSCSI traffic classes for the iSCSI partition; whereas all the NIC type partitions will use LAN TC (TC0) only. Hence, the patch enables querying of DCB configuration in MFP mode and configures TCs for iSCSI partition type. Though NIC type partitions may not have more than 1 TC enabled for them the port may have multiple TCs enabled and hence I40E_FLAG_DCB_ENABLED will be set/reset on all the partitions based on number of TCs on the port. This is required as in DCB environment it is expected that all traffic will be priority tagged.

2014-11-20i40e: don't overload fieldsMitch Williams
Overloading the msg_size field in the arq_event_info struct is just a bad idea. It leads to repeated bugs when the structure is used in a loop, since the input value (buffer size) is overwritten by the output value (actual message length). Fix this by splitting the field into two and renaming to indicate the actual function of each field. Since the arq_event struct has now changed, we need to change the drivers to support this. Note that we no longer need to initialize the buffer size each time we go through a loop as this value is no longer destroyed by arq processing. In the process, we also fix a bug in i40evf_verify_api_ver where the buffer size was not correctly reinitialized each time through the loop.

This patch allows the driver to enable/disable the XPS based on the number of TCs being enabled for the given VSI.

2014-11-18i40e: Modify Tx disable wait flow in case of DCB reconfigurationNeerav Parikh
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.

When the port TC configuration changes as a result of DCBx the driver modifies the enabled TCs for the VEBs it manages. But, in the process it did not update the enabled_tc value that it caches on a per VEB basis. So, when the next reconfiguration event occurs where the number of TC value is same as the value cached in enabled_tc for a given VEB; driver does not modify it's TC configuration by calling appropriate AQ command believing it is running with the same configuration as requested. Now, as the VEB is not actually enabled for the TCs that are there any TC configuration command for VSI attached to that VEB with TCs that are not enabled for the VEB fails.

2014-11-03i40e: scale msix vector use when more cores than vectorsShannon Nelson
When there are more cores than vectors available to the PF, scale back the LAN msix usage to force queue/vector sharing and leave some vectors for Flow Director, VMDq, etc. Change-ID: Ie0317732eb85ad8d851d7da7d9af86b1bf8c21ad Signed-off-by: Shannon Nelson <shannon.nelson@intel.com> Signed-off-by: Patrick Lu <patrick.lu@intel.com> Tested-by: Jim Young <jamesx.m.young@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
2014-11-03i40e: fix link checking logicMitch Williams
If the interface is closed, but VFs exist, current code will spam all the VFs with link messages every second. This is because the link event code was looking at netif_carrier_ok() without checking to see if the interface was actually open. Refactor the logic to only check the carrier state if the interface is actually open. This allows link changes to be reported correctly without spamming the VFs.
