2016-09-25i40evf: support queue-specific settings for interrupt moderationJacob Keller
In commit a75e8005d506f3 ("i40e: queue-specific settings for interrupt moderation") the i40e driver gained support for setting interrupt moderation values per queue. This patch adds support for this feature to the i40evf driver as well. In addition, a few changes are made to the i40e implementation to add function header documentation comments, as well. This behaves in a similar fashion to the implementation in i40e. Thus, requesting the moderation value when no queue is provided will report queue 0 value, while setting the value without a queue will set all queues at once.

2016-09-25i40evf: enable adaptive interrupt throttlingMitch Williams
All of the code to support adaptive interrupt throttling is already in the interrupt handler, it just needs to be enabled. Fill out the data structures properly to make it happen. Single-flow traffic tests may show slightly lower throughput, but interrupts per second will drop by about 75%.

The GSO types of SKB_GSO_IPIP and SKB_GSO_SIT are removed (these are both instances of SKB_GSO_IPXIP4). SKB_GSO_IPXIP6 will be used when support for GSO with IP encapsulation over IPv6 is added.

2016-05-06i40evf: refactor receive routineJesse Brandeburg
This is part 2 of the Rx refactor series, just including changes to i40evf. This refactor aligns the receive routine with the one in ixgbe which was highly optimized. This reduces the code we have to maintain and allows for (hopefully) more readable and maintainable RX hot path. In order to do this: - consolidate the receive path into a single function that doesn't use packet split but *does* use pages for Rx buffers. - remove the old _1buf routine - consolidate several routines into helper functions - remove VF ethtool control over packet split - remove priv_flags interface since it is unused Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Tested-by: Andrew Bowers <andrewx.bowers@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>

2016-05-02i40e/i40evf: Add support for GSO partial with UDP_TUNNEL_CSUM and GRE_CSUMAlexander Duyck
This patch makes it so that i40e and i40evf can use GSO_PARTIAL to support segmentation for frames with checksums enabled in outer headers. As a result we can now send data over these types of tunnels at over 20Gb/s versus the 12Gb/s that was previously possible on my system. The advantage with the i40e parts is that this offload is mostly transparent as the hardware still deals with the inner and/or outer IPv4 headers so the IP ID is still incrementing for both when this offload is performed.

2016-04-26i40e/i40evf: Clean up feature flagsAlexander Duyck
The feature flags list for i40e and i40evf is beginning to become pretty massive. I plan to add another 4 or so features to these drivers and duplicating the flags for each and every flags list is becoming a bit repetitive. The primary change here is that we now build our features list around hw_encap_features. After that we assign that to vlan_features, hw_features, and finally map that onto features. In addition we end up throwing features onto hw_encap_features that end up having no effect such as the Rx offloads and SCTP_CRC. However that should have no impact and makes things a bit easier for us as hw_encap_features is one of the less updated features maps available. For i40evf I went through and sanity checked a few features as well. Specifically RXCSUM was being set as a read-only feature which didn't make much sense. I have updated things so we can clear the NETIF_F_RXCSUM flag since that is really a software feature and not a hardware one anyway so disabling it is just a matter of ignoring the result from the hardware.

If the VF is reset via VFLR, the device will be knocked out of bus master mode, and the driver will fail to recover from the reset. Fix this by enabling bus mastering after every reset. In a non-VFLR case, the bus master bit will not be disabled, and this call will have no effect.

2016-02-04i40e/i40evf: Use private workqueueJesse Brandeburg
As done per ixgbe, use a private workqueue to avoid blocking the system workqueue. This avoids some strange side effects when some other entity is depending on the system work queue.

2016-02-04i40evf: null out ring pointers on freeMitch Williams
Since we check these ring pointers to make sure we don't double-allocate or double-free the rings, we had better null them out after we free them. In very rare cases this can cause a panic if the driver is removed during reset recovery.

2016-02-04i40evf: allow channel bonding of VFsMitch Williams
In some modes, bonding would not enslave VF interfaces. This is due to bonding calling change_mtu and the immediately calling open. Because of the asynchronous nature of the admin queue mechanism, the VF returns -EBUSY to the open call, because it knows the previous operation hasn't finished yet. This causes bonding to fail with a less-than-useful error message. To fix this, remove the check for pending operations at the beginning of open. But this introduces a new bug where the driver will panic on a quick close/open cycle. To fix that, we add a new driver state, __I40EVF_DOWN_PENDING, that the driver enters when down is called. The driver finally transitions to a fully DOWN state when it receives confirmation from the PF driver that all the queues are disabled. This allows open to complete even if there is a pending mtu change, and bonding is finally happy.
