2015-01-13i40evf: kick a stalled admin queueMitch A Williams2-1/+9
On some versions of the firmware, the VF admin send queue may become stalled. In this case, the easiest solution is to just place another descriptor on the queue; the firmware will then process both requests. The early init code already accounts for this, but the runtime code does not. In the watchdog task, check for the stall condition, and if it's found, send our API version to the PF. When the PF replies, just ignore the reply.

2015-01-13i40evf: don't fire traffic IRQs when the interface is downMitch A Williams1-4/+7
There is always a possibility that MSI-X interrupts can get lost. To keep this problem from stalling the driver, we fire all of our MSI-X vectors during the watchdog routine. However, we should not fire the traffic vectors when the interface is closed. In this case, just fire vector 0, which is used for admin queue events. As a result, we do not enable the interrupt cause for vector 0. This can cause the admin queue handler to be called reentrantly, which causes a scary "critical section violation" message to be logged, even though no real damage is done.

2015-01-13i40evf: refactor shutdown codeMitch A Williams1-6/+23
If the VF driver is running in the host, the shutdown code is completely broken. We cannot wait in our down routine for the PF to respond to our requests, as its admin queue task will never run while we hold the lock. Instead, we schedule operations, then let the watchdog take care of shutting things down. If the driver is being removed, then wait in the remove routine until the watchdog is done before continuing.

2015-01-13i40evf: Remove some scary log messagesMitch A Williams2-9/+1
These messages may be triggered during normal init of the driver if the PF or FW take a long time to respond. There's nothing really wrong, so don't freak people out logging messages. If the communication channel really is dead, then we'll retry a few times and give up. This will log a different more scary message that should cause consternation. This allows the user to more easily detect a genuine failure.

2015-01-13i40e: disable IOV before freeing resourcesMitch A Williams1-2/+9
If VF drivers are loaded in the host OS, the call to pci_disable_sriov() will cause these drivers' remove routines to be called. If the PF driver has already freed VF resources before this happens, then the VF remove routine can't properly communicate with the PF driver causing all sorts of mayhem and error messages and hurt feelings. To fix this, we move the call to pci_disable_sriov() up to the top of the function and let it complete before freeing any VF resources.

This patch causes the driver to detect this situation and force an interrupt to fire which will flush the stuck descriptor. Does not conflict with napi because if we are already polling the napi_schedule is ignored. Additionally the extra interrupts are rate limited, so don't cause a burden to the CPU.

2014-12-12fm10k/igb/ixgbe: Use dma_rmb on Rx descriptor readsAlexander Duyck3-11/+10
This change makes it so that dma_rmb is used when reading the Rx descriptor. The advantage of dma_rmb is that it allows for a much lower cost barrier on x86, powerpc, arm, and arm64 architectures than a traditional memory barrier when dealing with reads that only have to synchronize to coherent memory. In addition I have updated the code so that it just checks to see if any bits have been set instead of just the DD bit since the DD bit will always be set as a part of a descriptor write-back so we just need to check for a non-zero value being present at that memory location rather than just checking for any specific bit. This allows the code itself to appear much cleaner and allows the compiler more room to optimize.

2014-12-09i40e: check for AQ timeout in aq_rc decodeShannon Nelson3-14/+33
Decoding the AQ return code is great except when the AQ send timed out and there's no return code set. This changes the handy decoder interface to help catch and properly report the condition as a useful errno rather than returning a misleading '0'.

2014-12-09i40e: poll on NVM semaphore only if not other errorShannon Nelson1-4/+9
Only poll on the NVM semaphore if there's time left on a previous reservation. Also, add a little more info to debug messages.

2014-12-09i40e: fix up NVM update sm error handlingShannon Nelson1-10/+16
The state transitions after an error were not managed well, so these changes get us back to the INIT state or don't transition out of the INIT state after most errors.

2014-12-09i40e: set max limit for access pollingShannon Nelson3-15/+10
Don't bother trying to set a smaller timeout on the polling, just simplify the code and always use the max limit. Also, rename a variable for clarity and fix a comment.
