2015-02-08i40evf: reset on module unloadMitch Williams1-5/+10
When the module is being unloaded, don't wait for the PF to politely handle all of our admin queue requests, as that might take forever with a lot of VFs enabled. Instead, just stop everything and request a VF reset. When the original shutdown code was written, VF resets were unreliable, so we avoided them. But with production hardware and firmware, and the 1.x PF driver, this is no longer the case. This fixes a potential multi-minute delay on driver unload, VF disable, or system shutdown.

2015-01-16i40e: Support for NPAR iSCSI partition with DCBNeerav Parikh1-0/+1
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.

When in NPAR mode the driver instance might be controlling the base partition or one of the other "fake" PFs. There are some things that can only be done by the base partition, aka partition_id 1. This code does a bit of work to find how many partitions are there per port and what is the current partition_id.

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.

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.

The NVM update operations take time finish asynchronously, and follow-on update requests need to wait for the current one to finish.

The released firmware handles the busy state correctly, returning I40E_AQ_RC_EBUSY if an update is still in progress, so the code no longer needs to track this.

2014-12-08ethtool: Support for configurable RSS hash functionEyal Perry1-2/+15
This patch extends the set/get_rxfh ethtool-options for getting or setting the RSS hash function. It modifies drivers implementation of set/get_rxfh accordingly. This change also delegates the responsibility of checking whether a modification to a certain RX flow hash parameter is supported to the driver implementation of set_rxfh. User-kernel API is done through the new hfunc bitmask field in the ethtool_rxfh struct. A bit set in the hfunc field is corresponding to an index in the new string-set ETH_SS_RSS_HASH_FUNCS. Got approval from most of the relevant driver maintainers that their driver is using Toeplitz, and for the few that didn't answered, also assumed it is Toeplitz.

2014-12-06i40evf: make early init sequence even more robustMitch Williams2-13/+12
When multiple VFs attempt to initialize simultaneously, the firmware may delay or drop messages. Make the init code more adept at handling these situations by a) reinitializing the admin queue if the firmware fails to process a request, and b) resending a request if the PF doesn't answer. Once the request has been sent again, the PF might end up getting both requests and send the configuration information to the driver twice. This will cause the VF to complain about receiving an unexpected message from the PF. Since this is not fatal, reduce the warning level of the log messages that are generated in response to this event.

2014-11-20i40e: don't overload fieldsMitch Williams4-14/+13
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.

2014-08-27i40e/i40evf: Ignore a driver perceived Tx hang if the number of desc pending < 4Anjali Singhai Jain2-2/+5
We are seeing situations where the driver sees a hang with less than 4 desc pending, if the driver chooses to ignore it the queue progresses forward and the stack never experiences a real hang. With this patch we will log a stat when this situation happens "tx_sluggish" will increment and we can see some more details at a higher debug level. Other than that we will ignore this particular case of Tx hang.

2014-08-27i40e/i40evf: add max buf len to aq debug print helperShannon Nelson3-9/+14
There is at least one case in the Firmware API where the response to a command changes the buffer size field in the AQ descriptor to a larger number than what the request's buffer size started as. This is in addition to setting an error flag and is in order to tell the requester how much larger a buffer is required for the answer. We need to be sure not to use that number when dumping the contents of the data buffer because it can send us into the weeds and generate an invalid pointer exception. This patch adds a max buffer size parameter to the print helper to be sure the code knows when to stop.
