Add IFLA_BOND_NUM_PEER_NOTIF to allow get/set of bonding parameter num_grat_arp via netlink. Bonding parameter num_unsol_na is synonymous with num_grat_arp, so add only one netlink attribute to represent both bonding parameters.

netback already has code which parses IPv4 and v6 headers to set up checksum offsets and these are always applied to GSO packets being sent from frontends. It's therefore suboptimal that GSOs are being marked SKB_GSO_DODGY to defer the gso_segs calculation when netback already has all necessary information to hand to do the calculation. This patch adds that calculation.

It can be a bit confusing when looking for checksumming flags that the actual comment for this resides elsewhere further below in the header file. Thus, bring the documentation where we define these flags, and slightly improve the doc text to make it a bit more clear/readable. Also, whitespace-align values of the define while at it.

This patch implements the first size-based qdisc that attempts to differentiate between small flows and heavy-hitters. The goal is to catch the heavy-hitters and move them to a separate queue with less priority so that bulk traffic does not affect the latency of critical traffic. Currently "less priority" means less weight (2:1 in particular) in a Weighted Deficit Round Robin (WDRR) scheduler. In essence, this patch addresses the "delay-bloat" problem due to bloated buffers. In some systems, large queues may be necessary for obtaining CPU efficiency, or due to the presence of unresponsive traffic like UDP, or just a large number of connections with each having a small amount of outstanding traffic. In these circumstances, HHF aims to reduce the HoL blocking for latency sensitive traffic, while not impacting the queues built up by bulk traffic. HHF can also be used in conjunction with other AQM mechanisms such as CoDel. To capture heavy-hitters, we implement the "multi-stage filter" design in the following paper: C. Estan and G. Varghese, "New Directions in Traffic Measurement and Accounting", in ACM SIGCOMM, 2002. Some configurable qdisc settings through 'tc': - hhf_reset_timeout: period to reset counter values in the multi-stage filter (default 40ms) - hhf_admit_bytes: threshold to classify heavy-hitters (default 128KB) - hhf_evict_timeout: threshold to evict idle heavy-hitters (default 1s) - hhf_non_hh_weight: Weighted Deficit Round Robin (WDRR) weight for non-heavy-hitters (default 2) - hh_flows_limit: max number of heavy-hitter flow entries (default 2048) Note that the ratio between hhf_admit_bytes and hhf_reset_timeout reflects the bandwidth of heavy-hitters that we attempt to capture (25Mbps with the above default settings). The false negative rate (heavy-hitter flows getting away unclassified) is zero by the design of the multi-stage filter algorithm. With 100 heavy-hitter flows, using four hashes and 4000 counters yields a false positive rate (non-heavy-hitters mistakenly classified as heavy-hitters) of less than 1e-4.

IPV6_PMTU_INTERFACE is the same as IPV6_PMTU_PROBE for ipv6. Add it nontheless for symmetry with IPv4 sockets. Also drop incoming MTU information if this mode is enabled. The additional bit in ipv6_pinfo just eats in the padding behind the bitfield. There are no changes to the layout of the struct at all.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series contains updates to i40e, ixgbevf, ixgbe and igb. Don provides an ixgbevf patch to add DCB configuration into the queue setup so that we won't have to allocate queues in a separate place when enabling DCB. Guenter Roeck provides 2 patches for ixgbe to simplify the code by attaching hwmon sysfs attributes to hwmon device instead of PCI device. Also fix an issues where the temperature sensor attribute index was being started with the value 0 and not 1 as per the hwmon API. Carolyn provides igb patches to fix queue allocation method to accommodate changes during runtime. This includes changing how the driver initializes MSIx and checks for MSIx configuration to make it easier to reconfigure the device when queue changes happen at runtime. Neerav and Shannon fixes i40e debugfs commands that dump hex information by using print_hex_dump(). Shannon provides several i40e fixes which include the prevention of null pointer exception in the dump descriptor by checking that rings were allocated before trying to reference them. Fixed up a couple of scanfs to accept various base numbers instead of silently requiring hex. Anjali fixes up i40e where the incorrect defines were being used for misc interrupts. Alan Cox provides a fix for i40e where we assume that the resulting buffer is zero terminated when we then re-use it. The sscanf is limited to 512 bytes but needs to be 511 to allow for a terminator. Stephen Hemminger fixes i40e by making local functions static and removes unused code (i40e_aq_add/remove_vlan() functions). ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

When changing number of queues using ethtool's set_channels during runtime, a queue allocation could fail, which can leave the device in a down state. In order to preserve the usability of the device in this scenario, this patch changes the driver to allocate the number of queues only if they have not been allocated already. The first allocation is then done for the max number of queues, which is the default queues for this driver. With this change, queue quantity changes are not subject to queue allocation failures.

Simplify the code. Attach hwmon sysfs attributes to hwmon device instead of pci device. Avoid race conditions caused by attributes being created after hwmon device registration. Implicitly (through hwmon API) add mandatory 'name' sysfs attribute. Other cleanup: Instead of allocating memory for hwmon attributes, move attributes and all other hwmon related data into struct hwmon_buff and allocate the entire structure using devm_kzalloc. Check return value from calls to igb_add_hwmon_attr() one by one instead of logically combining them all together.
