2014-01-09i40e: use kernel specific definesJesse Brandeburg

2014-01-09i40e: Re-enable interrupt on ICR0Anjali Singhai Jain
The hardware can occasionally give an interrupt on the misc queue for which there is no driver work to do. In that case the driver was not re-enabling interrupts even though they were auto masked by hardware. This left interrupts disabled on this queue. Re-enable the interrupt whenever leaving this function.

2014-01-07i40e: correctly setup ARQ descriptorsMitch Williams
When cleaning descriptors, we must set up ALL fields, not just the DMA address. The initial setup does this correctly, but not the cleanup code, so the firmware would process the ring exactly once and then fail.

2014-01-07i40e: remove redundant AQ enableKamil Krawczyk
The admin queue length register is updated in config_a<sq|rq>_regs functions. We should not update it again, as we will trigger firmware to init the AQ again. In this case firmware will lose the information about the AQ Rx tail position and will see Rx queue as full (no free desc for FW to use).

2014-01-06i40e: support VFs on PFs other than 0Mitch Williams
When communicating with VF devices over the AQ, the FW refers to the VF by its global VF ID, not local the VF ID with reference to its parent PF. Since the global and local VF IDs are identical for PF 0, the code worked correctly on PF 0. However, we cannot just use global IDs throughout the code as most of the other references to the VF (VSI setup, register offsets, etc.) require the local VF ID. Instead, we just add or subtract our base VF ID when sending and receiving AQ messages.

2014-01-06i40e: Do not enable default port on the VEBGreg Rose
Enabling the default port on the VEB causes all outgoing traffic from virtual functions to be copied to the physical function. The default port is only supposed to be used if you wish to bridge the physical function to a SW switch such as Open vSwitch or the Linux bridge. That allows the SW switch to route traffic to VMs that are not using a virtual function. Eventually we'll want to implement the ndo_fdb_add, ndo_fdb_del, and ndo_fdb_dump functions. The ndo_fdb_add function would set the default port on the VEB in those cases where the MAC/VLAN address filters have overflowed. Normally we would not want to use it.

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.

2014-01-04i40e: guard against vf message racesMitch Williams
When disabling and enabling VFs on a live system with the VF driver loaded, it's possible to receive an admin queue message from the VF driver at an inconvenient time, e.g. when the associated data structures aren't present or configured. This causes a rather inconvenient panic. To guard against this, we change the order of when we set num_alloc_vfs when turning off SR-IOV, and then gate processing of any VF messages based upon that value. Likewise, when enabling VFs, we shut off the relevant interrupt until configuration is complete.

2014-01-04i40e: Change the ethtool NVM read method to use AQAnjali Singhai Jain
Earlier we were reading Shadow RAM (copy of the NVM) which can differ from the actual NVM. Use AQ instead to read the actual NVM.

2014-01-03i40e: report VF MAC addresses correctlyMitch Williams
If the user does not assign a VF MAC address, then just report it as zero. Attempting to guess the correct primary MAC address of the VF is a futile and heartbreaking endeavour.
