Implement a new helper function fwnode_get_next_available_child_node(), which enables obtaining next enabled child fwnode, which works on a similar basis to OF's of_get_next_available_child(). This commit also introduces a macro, thanks to which it is possible to iterate over the available fwnodes, using the new function described above. Signed-off-by:

Until now there were two very similar functions allowing to get Linux IRQ number from ACPI handle (acpi_irq_get()) and OF node (of_irq_get()). The first one appeared to be used only as a subroutine of platform_irq_get(), which (in the generic code) limited IRQ obtaining from _CRS method only to nodes associated to kernel's struct platform_device. This patch introduces a new helper routine - fwnode_irq_get(), which allows to get the IRQ number directly from the fwnode to be used as common for OF/ACPI worlds. It is usable not only for the parents fwnodes, but also for the child nodes comprising their own _CRS methods with interrupts description. In order to be able o satisfy compilation with !CONFIG_ACPI and also simplify the new code, introduce a helper macro (ACPI_HANDLE_FWNODE), with which it is possible to reach an ACPI handle directly from its fwnode.

Until now there were two almost identical functions for obtaining network PHY mode - of_get_phy_mode() and, more generic, device_get_phy_mode(). However it is not uncommon, that the network interface is represented as a child of the actual controller, hence it is not associated directly to any struct device, required by the latter routine. This commit allows for getting the PHY mode for children nodes in the ACPI world by introducing a new function - fwnode_get_phy_mode(). This commit also changes device_get_phy_mode() routine to be its wrapper, in order to prevent unnecessary duplication. Signed-off-by:

Jiri Pirko says: ==================== mlxsw: spectrum_router: Optimize LPM trees Ido says: This set tries to optimize the structure of the LPM trees used for route lookup by avoiding lookups that are guaranteed not to return a result. This is done by making sure only used prefix lengths are present in the tree. First two patches are small preparatory steps towards the actual change in the last patch. ==================== Signed-off-by: -
Ido Schimmel authored
In commit fc922bb0 ("mlxsw: spectrum_router: Use one LPM tree for all virtual routers") I tried to make sure only used prefix lengths are present in the LPM tree shared between all virtual routers. However, this optimization had to be removed in commit a69518cf ("mlxsw: spectrum_router: Avoid expensive lookup during route removal"), since determining the used prefix lengths required us to traverse all the active virtual routers, which could result in a hung task depending on the number of VRFs and whether routes were removed due to abort or not. Re-introduce the optimization by moving the prefix usage accounting from the virtual routers to the LPM tree, as this accounting is only used in order to determine the tree's structure. To make the sharing of the trees more explicit, the two trees (for IPv4 and IPv6) are stored in the shared router struct and upon the creation of a virtual router it is immediately bound to both.

Next patch will try to optimize the LPM tree and make sure only used prefix lengths are present, to avoid unnecessary look-ups. Pass the currently removed FIB node to the unlinking function as its associated prefix length is a potential candidate for removal from the tree. Signed-off-by:

Ido Schimmel authored
Currently, each FIB (IPv4 / IPv6) in a virtual router holds a prefix usage that is used to choose a matching LPM tree, but also to check if the FIB is empty, so that the LPM tree could be unbound. Next patches will remove the reliance on the per-FIB prefix usage for LPM tree matching. Keeping it only to check if the FIB is empty is a waste, since we can use the nodes ({Prefix, Length}) list instead. Signed-off-by: -

A number of new AQC devices is going to be released. To support more flexible capabilities management a number of static caps instances is now declared. Devices now are mainly differs by supported speeds, but in future more parameters will be customized. A set of AQC100 devices have fibre media, not twisted pair - this is also reflected in new capabilities definitions. HW level also now directly exports hw_ops for each of A0/B0 hardware. PCI configuration now uses a device configuration table where each device ID is explicitly mapped with hardware OPs and capabilities structures. Signed-off-by:

Saeed Mahameed says: ==================== mlx5-updates-2018-01-19 From: Or Gerlitz <ogerlitz@mellanox.com> ======= First six patches of this series further enhances the mlx5 hairpin support. The first two patches deal with using different hairpin instances for flows whose packets have different priorities to align with the port TX QoS model. The next four patches allow us to do HW spreading of flows over a set of hairpin pairs using RSS. The last two patches change the driver to also set the size of the HW hairpin queues. ======== Next four patches from Eran Ben Elisha <eranbe@mellanox.com>: Add more debug data for TX timeout handling, and further enhance and optimize TX timeout handling upon lost interrupts, which adds a mechanism for explicitly polling EQ in case of a TX timeout in order to recover from a lost interrupt. If this is not the case (no pending EQEs), perform a channels full recovery as usual. From Kamal Heib <kamalh@mellanox.com>, Two patches to extend the stats group API to have an update_stats() callback which will be used to fetch the hardware or software counters data, this will improve the current API and reduce code duplication.

Previously it was possible to interrupt processing stats updates because they were handled in a work queue. Interrupting the stats updates could lead to a situation where we backup the control message queue. This patch moves the stats update processing out of the work queue to be processed as soon as hardware sends a request. Reported-by:

Pablo Neira Ayuso says: ==================== Netfilter/IPVS updates for net-next The following patchset contains Netfilter/IPVS updates for your net-next tree. Basically, a new extension for ip6tables, simplification work of nf_tables that saves us 500 LoC, allow raw table registration before defragmentation, conversion of the SNMP helper to use the ASN.1 code generator, unique 64-bit handle for all nf_tables objects and fixes to address fallout from previous nf-next batch. More specifically, they are: 1) Seven patches to remove family abstraction layer (struct nft_af_info) in nf_tables, this simplifies our codebase and it saves us 64 bytes per net namespace. 2) Add IPv6 segment routing header matching for ip6tables, from Ahmed Abdelsalam. 3) Allow to register iptable_raw table before defragmentation, some people do not want to waste cycles on defragmenting traffic that is going to be dropped, hence add a new module parameter to enable this behaviour in iptables and ip6tables. From Subash Abhinov Kasiviswanathan. This patch needed a couple of follow up patches to get things tidy from Arnd Bergmann. 4) SNMP helper uses the ASN.1 code generator, from Taehee Yoo. Several patches for this helper to prepare this change are also part of this patch series. 5) Add 64-bit handles to uniquely objects in nf_tables, from Harsha Sharma. 6) Remove log message that several netfilter subsystems print at boot/load time. 7) Restore x_tables module autoloading, that got broken in a previous patch to allow singleton NAT hook callback registration per hook spot, from Florian Westphal. Moreover, return EBUSY to report that the singleton NAT hook slot is already in instead. 8) Several fixes for the new nf_tables flowtable representation, including incorrect error check after nf_tables_flowtable_lookup(), missing Kconfig dependencies that lead to build breakage and missing initialization of priority and hooknum in flowtable object. 9) Missing NETFILTER_FAMILY_ARP dependency in Kconfig for the clusterip target. This is due to recent updates in the core to shrink the hook array size and compile it out if no specific family is enabled via .config file. Patch from Florian Westphal. 10) Remove duplicated include header files, from Wei Yongjun. 11) Sparse warning fix for the NFPROTO_INET handling from the core due to missing static function definition, also from Wei Yongjun. 12) Restore ICMPv6 Parameter Problem error reporting when defragmentation fails, from Subash Abhinov Kasiviswanathan. 13) Remove obsolete owner field initialization from struct file_operations, patch from Alexey Dobriyan. 14) Use boolean datatype where needed in the Netfilter codebase, from Gustavo A. R. Silva. 15) Remove double semicolon in dynset nf_tables expression, from Luis de Bethencourt. ==================== Signed-off-by: -
