* i40e: cleanup stringsJesse Brandeburg2014-03-141-27/+20
| | | | | | | | | | | | This patch cleans up the strings that the driver prints during normal operation and moves many strings into dev_dbg. It also cleans up strings printed during reset.

* i40e: delete netdev after deleting napi and vectorsShannon Nelson2014-03-141-2/+4
| | | | | | | | | | | | We've been deleting the netdev before getting around to deleting the napi structs. Unfortunately, we then didn't delete the napi structs because we have a check for netdev, thus we were leaving garbage around in the system.

* i40e: fix nvm version and remove firmware reportJesse Brandeburg2014-03-061-7/+0
| | | | | | | | | | | | | | | | | The driver needs to use the format that the current NVM uses when printing the version of the NVM. It should remain this way from now on forward. The driver was reporting when firmware was less than an expected version number, but this is not a requirement for the product and we print the firmware number at init and in ethtool -i output. Just remove the print.

* i40e: add DCB and DCBNL supportNeerav Parikh2014-01-171-18/+308
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* i40e: refactor flow directorAnjali Singhai Jain2014-01-171-158/+183
| | | | | | | | | | | | | | | | | | | The i40e hardware was generating some inconsistent results when using current programming methods. This refactor fixes the inconsistencies that were preventing clean unloads of the driver, and moves the queues for handling flow director errors into their own hardware VSI. This patch also implements a corrected version of the basic ethtool add ntuple rule, which will disable the driver's automatic flow programming. A future patch adds remove/replay/list support for ntuple.

* i40e: disable packet splitJesse Brandeburg2014-01-091-1/+0
| | | | | | | | | | | | The driver and hardware support splitting packets on headers but with the use of GRO we don't need the extra bus overhead, so make this driver more like igb and ixgbe and disable packet split.

* i40e: add a comment on barrier and fix panic on resetGreg Rose2014-01-091-4/+11
| | | | | | | | | | | | | | The memory barrier used in maybe_stop_tx can use a comment. Also add checks to VSI->rx_rings to ensure a kernel panic is not induced.

* i40e: Re-enable interrupt on ICR0Anjali Singhai Jain2014-01-091-4/+6
| | | | | | | | | | | | | | | 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.

* i40e: Stop accepting any VLAN tag on VLAN 0 filter setGreg Rose2014-01-071-11/+0
| | | | | | | | | | | | | When the 8021q driver is loaded it sets VLAN 0 filters on all devices. This does not mean that any VLAN tagged packet should be accepted. Instead accept only VLAN 0 tagged packets so that upper layers can interpret the priority bits.

| | | | | | | | | | | | | | | Broadcast promiscuous should only be turned on when general promiscuous mode is turned on, otherwise VLAN tagged packets out of the assigned VLAN domain are received. Add a broadcast MAC filter in order to continue to receive broadcast traffic on VLANs, MAIN or VMDQ VSI.

| | | | | | | | | | | | | | | | | Always call the AQ call to shutdown the queue in the shutdown path. Check ASQ is alive before issuing the AQ command since we might be resetting to recover from a bad state in which case we should not issue the AQ command. Use the register variable for length so it can be used by PF, VF and GL AQ commands.
