2014-01-05i40e: I40E_FLAG_MQ_ENABLED is not usedNeerav Parikh

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: fix error handling when alloc of vsi array failsShannon Nelson
Swap a couple lines around in the error handling if the kzalloc() for the pf->vsi array fails. This was causing a kernel BUG because the call to i40e_clear_interrupt_scheme() was assuming the pf->vsi[] array existed. In this fix it is possible that i40e_reset_interrupt_capability() will get called twice, but this is a safe action.

2014-01-04i40e: reinit buffer size each timeMitch Williams
When cleaning the ARQ, we must reinitialize the buffer size each time we go through the loop, because i40e_clean_arq_element returns the message length in the same field. Without this change, subsequent messages can be truncated to the length of the previous message.

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.

Prevent this issue by handling the HMC error case explicitly, and only reset if the interrupt was from some of the other causes.

2013-12-16i40e: use same number of queues as CPUsJesse Brandeburg
The current driver default sets the number of transmit/receive queue pairs based on the current node's CPU count. A better method is to use the total number of CPUs in the system to suggest the number of queue pairs, which aligns better with the behavior of ixgbe, and also with the expectations of the kernel XPS and other subsystems in the stack.

2013-10-22i40e: fixup legacy interrupt handlingShannon Nelson
There were a number of little bugs in the error handling of irq setup, most of which ended up panicing the kernel, and are addressed by this patch, along with a couple formatting issues. Legacy interrupts (including MSI) are used only in the case of failure to allocate MSI-X interrupts.

2013-10-22i40e: don't free nonexistent ringsMitch Williams
Not all VSIs have rings! Check to see if rings were actually allocated before freeing them. This prevents a panic when tx_rings[0] is not allocated.

2013-10-22i40e: do not flush after re-enabling interruptsJesse Brandeburg
Hot path doesn't need read-flush after interrupt enable, and this flush really causes a lot of extra cpu utilization. Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Tested-by: Kavindya Deegala <kavindya.s.deegala@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>

2013-10-09i40e: Add support for 64 bit netstatsAlexander Duyck
This change brings support for 64 bit netstats to the driver. Previously the stats were 64 bit but highly racy due to the fact that 64 bit transactions are not atomic on 32 bit systems. This change makes is so that the 64 bit byte and packet stats are reliable on all architectures.
