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.

2014-01-17i40e: Change firmware workaroundJesse Brandeburg
Remove a workaround that is no longer necessary and implement a better understanding of what firmware is returning in the MSI-X vector count. This makes it so that the driver ends up with the right amount of queues when using all available MSI-X vectors.

None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

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.

2014-01-03i40e: refactor VF reset flowMitch Williams
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: add wake-on-lan supportShannon Nelson
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.

Be careful not to use the safe reset when cleaning up from the diagnostic tests, which avoids rtnl_lock recursion from ethtool. Protect the reset_task with rtnl_lock, since it runs from a work item.

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.
