If the PF driver reports proper support, allow the PF driver to configure RSS on the behalf of the VF driver. This will allow for RSS support on future hardware without changes to the VF driver. Unfortunately, the old RSS code still needs to stay as the driver needs to be compatible with PF drivers that don't support this interface. But this change still simplifies the data structures a bunch and makes this code simpler to read and maintain. Change-ID: I0375aad40788ecdc0cb24d5cfeccf07804e69771 Signed-off-by:

Under some circumstances the driver remove function may be called before the driver is fully initialized. So we can't assume that we know where our towel is at, or that all of the data structures are initialized. To ensure that we don't panic, check that the vsi_res pointer is valid before dereferencing it. Then drink beer and eat peanuts. Change-ID: If697b4db57348e39f9538793e16aa755e3e1af03 Signed-off-by:

Add support for configuring RSS on behalf of the VFs. This removes the burden of dealing with different hardware interfaces from the VF drivers, allowing for better future compatibility. Change-ID: Icea75d3f37241ee8e447be5779e5abb53ddf04c0 Signed-off-by:

Looking over the documentation it turns out enabling IPIP and SIT offloads for i40e is pretty straightforward. As such I decided to enable them with this patch. In my testing I am seeing an improvement of 8 to 10 Gb/s for IPIP and SIT tunnels with this offload enabled. Signed-off-by:

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.

There's some inconsistency in current logic determining whether the link settings of a given interface can be changed; I.e., in all modes other than the so-called `deault' mode the interfaces are forbidden from changing the configuration - but even this rule is not applied to all user APIs that may change the configuration. Instead, let the core-module [qed] decide whether an interface can change the configuration by supporting a new API function. We also revise the current rule, allowing all interfaces to change their configurations while laying the infrastructure for future modes where an interface would be blocked from making such a configuration.

Jeff Kirsher says: ==================== 10GbE Intel Wired LAN Driver Updates 2016-04-25 This series contains updates to ixgbe and ixgbevf. Emil provides several patches, starting with the consolidation of the logic behind configuring spoof checking. Fixed an issue which was causing link issues for backplane devices because x550em_a/x devices did not have a default value for mac->ops.setup_link. Refactored the ethtool stats to bring the logic closer to how ixgbe handles stats and sets up per-queue stats for ixgbevf. Mark adds a new register to wait for previous register writes to complete before issuing a register read, which is needed when slower links are in use. Fixed the flow control setup for x550em_a, the incorrect fc_setup function was being used. Don added a workaround for empty SFP+ cage crosstalk, since on some systems the crosstalk could lead to link flap on empty SFP+ cages. Jake converts ixgbe and ixgbevf to use the BIT() macro. Alex Duyck adds support for partial GSO segmentation in the case of tunnels for ixgbe and ixgbevf. Then preps for HyperV by moving the API negotiation into mac_ops. Arnd Bergmann provides a fix for the ARM compile warnings in linux-next by converting the use of a udelay() to msleep(). ==================== Signed-off-by: -

Nicolas Dichtel says: ==================== netlink: align attributes when needed (patchset #2) This is the continuation (series #2) of the work done to align netlink attributes when these attributes contain some 64-bit fields. In patch #3, I didn't modify the function ila_encap_nlsize(). I was waiting feedback for this patch: http://patchwork.ozlabs.org/patch/613766/ If it's approved, there will be an update to switch nla_total_size() to nla_total_size_64bit() after the merge of net in net-next. ==================== Signed-off-by:

d894ba18 ("soreuseport: fix ordering for mixed v4/v6 sockets") was merged as a bug fix to the net tree. Two conflicting changes were committed to net-next before the above fix was merged back to net-next: ca065d0c ("udp: no longer use SLAB_DESTROY_BY_RCU") 3b24d854 ("tcp/dccp: do not touch listener sk_refcnt under synflood") These changes switched the datastructure used for TCP and UDP sockets from hlist_nulls to hlist. This patch applies the necessary parts of the net tree fix to net-next which were not automatic as part of the merge.

The newly added x550em_a support causes a link failure on ARM because of an overly long time passed into udelay(): ERROR: "__bad_udelay" [drivers/net/ethernet/intel/ixgbe/ixgbe.ko] undefined! There are multiple variants of the ixgbe_acquire_swfw_sync_*() function, and the other ones all use msleep(), so we can safely assume that all callers are allowed to sleep, which makes msleep() a better replacement than mdelay().

This patch moves API negotiation into mac_ops. The general idea here is that with HyperV on the way we need to make certain that anything that will have different versions between HyperV and a standard VF needs to be abstracted enough so that we can have a separate function between the two so we can avoid changes in one breaking something in the other.

This patch adds support for partial GSO segmentation in the case of tunnels. Specifically with this change the driver an perform segmentation as long as the frame either has IPv6 inner headers, or we are allowed to mangle the IP IDs on the inner header. This is needed because we will not be modifying any fields from the start of the start of the outer transport header to the start of the inner transport header as we are treating them like they are just a block of IP options.

Several areas of ixgbe were written before widespread usage of the BIT(n) macro. With the impending release of GCC 6 and its associated new warnings, some usages such as (1 << 31) have been noted within the ixgbe driver source. Fix these wholesale and prevent future issues by simply using BIT macro instead of hand coded bit shifts. Also fix a few shifts that are shifting values into place by using the 'u' prefix to indicate unsigned. It doesn't strictly matter in these cases because we're not shifting by too large a value, but these are all unsigned values and should be indicated as such. Signed-off-by:

This brings the logic closer to how we handle the stats in ixgbe and it sets us up for introducing per-queue stats. Use IXGBEVF_STAT and IXGBEVF_NETDEV_STAT for accessing the driver and netdev stats respectively. This way we don't have to calculate the stats based on register values which could lead to the counters not being initialized properly when the interface is down. IXGBEVF_QUEUE_STATS_LEN is set to include the number of queues. Also some defines were renamed to use the IXGBEVF prefix. Signed-off-by:
