Add install and remove offload functionality for qos offloads. We first check that a police filter can be implemented by the VF rate limiting feature in hw, then we install the filter via the qos infrastructure. Finally we implement the mechanism for removing these types of filters. Signed-off-by:

Introduce matchall filter offload infrastructure that is needed to offload qos features like policing. Subsequent patches will make use of police-filters for ingress rate limiting. Signed-off-by:

Some actions like the police action are stateful and could share state between devices. This is incompatible with offloading to multiple devices and drivers might want to test for shared blocks when offloading. Store a pointer to the tcf_block structure in the tc_cls_common_offload structure to allow drivers to determine when offloads apply to a shared block. Signed-off-by:

Extends matchall offload to make use of the hardware intermediate representation. More specifically, this patch moves the native TC actions in cls_matchall offload to the newer flow_action representation. This ultimately allows us to avoid a direct dependency on native TC actions for matchall. Signed-off-by:

Petr Štetiar says: ==================== of_net: Add NVMEM support to of_get_mac_address this patch series is a continuation of my previous attempt[1], where I've tried to wire MTD layer into of_get_mac_address, so it would be possible to load MAC addresses from various NVMEMs as EEPROMs etc. Predecessor of this patch which used directly MTD layer has originated in OpenWrt some time ago and supports already about 497 use cases in 357 device tree files. During the review process of my 1st attempt I was told, that I shouldn't be using MTD directly, but that I should rather use new NVMEM subsystem and during the review process of v2 I was told, that I should handle EPROBE_DEFFER error as well, during the review process of v3 I was told, that returning pointer/NULL/ERR_PTR is considered as wrong API design, so this v4 patch series tries to accommodate all this previous remarks. First patch is wiring NVMEM support directly into of_get_mac_address as it's obvious, that adding support for NVMEM into every other driver would mean adding a lot of repetitive code. This patch allows us to configure MAC addresses in various devices like ethernet and wireless adapters directly from of_get_mac_address, which is used by quite a lot of drivers in the tree already. Second patch is simply updating documentation with NVMEM bits, and cleaning up all current binding documentation referencing any of the MAC address related properties. Third and fourth patches are simply removing duplicate NVMEM code which is no longer needed as the first patch has wired NVMEM support directly into of_get_mac_address. Patches 5-10 are converting all current users of of_get_mac_address to the new ERR_PTR encoded error value, as of_get_mac_address could now return valid pointer, NULL and ERR_PTR. Just for a better picture, this patch series and one simple patch[2] on top of it, allows me to configure 8Devices Carambola2 board's MAC addresses with following DTS (simplified): &spi { flash@0 { partitions { art: partition@ff0000 { label = "art"; reg = <0xff0000 0x010000>; read-only; nvmem-cells { compatible = "nvmem-cells"; #address-cells = <1>; #size-cells = <1>; eth0_addr: eth-mac-addr@0 { reg = <0x0 0x6>; }; eth1_addr: eth-mac-addr@6 { reg = <0x6 0x6>; }; wmac_addr: wifi-mac-addr@1002 { reg = <0x1002 0x6>; }; }; }; }; }; }; ð0 { nvmem-cells = <ð0_addr>; nvmem-cell-names = "mac-address"; }; ð1 { nvmem-cells = <ð1_addr>; nvmem-cell-names = "mac-address"; }; &wmac { nvmem-cells = <&wmac_addr>; nvmem-cell-names = "mac-address"; }; 1. https://patchwork.ozlabs.org/patch/1086628/ 2. https://patchwork.ozlabs.org/patch/890738/ ==================== Signed-off-by: -

There was NVMEM support added directly to of_get_mac_address, and it uses nvmem_get_mac_address under the hood, so we can remove it. As of_get_mac_address can now return ERR_PTR encoded error values, adjust to that as well. Signed-off-by:

As of_get_mac_address now supports NVMEM under the hood, we need to update the bindings documentation with the new nvmem-cell* properties, which would mean copy&pasting a lot of redundant information to every binding documentation currently referencing some of the MAC address properties. So I've just removed all the references to the optional MAC address properties and replaced them with the small note referencing net/ethernet.txt file. Signed-off-by:

Many embedded devices have information such as MAC addresses stored inside NVMEMs like EEPROMs and so on. Currently there are only two drivers in the tree which benefit from NVMEM bindings. Adding support for NVMEM into every other driver would mean adding a lot of repetitive code. This patch allows us to configure MAC addresses in various devices like ethernet and wireless adapters directly from of_get_mac_address, which is already used by almost every driver in the tree. Predecessor of this patch which used directly MTD layer has originated in OpenWrt some time ago and supports already about 497 use cases in 357 device tree files.

bnxt_need_reserve_rings() determines if any resources have changed and requires new reservation with firmware. The NQ checking is currently just an approximation. Improve the NQ checking logic to make it accurate. NQ reservation is only needed on 57500 PFs. This fix will eliminate unnecessary reservations and will reduce NQ reservations when some NQs have been released on 57500 PFs.

Jeff Kirsher says: ==================== 100GbE Intel Wired LAN Driver Updates 2019-05-04 This series contains updates to the ice driver only. Jesse updated the driver to make more functions consistent in their use of a local variable for vsi->back. Updates the driver to use bit fields when possible to avoid wasting lots of storage space to store single bit values. Optimized the driver to be more memory efficient by moving structure members around that are not in are hot path. Michal updates the driver to disable the VF if malicious device driver (MDD) event is detected by the hardware. Adds checks to validate the messages coming from the VF driver. Tightens up the sniffing of the driver so that transmit traffic so that VF's cannot see what is on other VSIs. Tony fixed the driver so that receive stripping state won't change every time transmit insertion is changed. Cleanup the __always_unused attribute, now that the variable is being used. Fixed the function which evaluates setting of features to ensure that can evaluate and set multiple features in a single function call. Akeem fixes the driver so that we do not attempt to remove a VLAN filter that does not exist. Adds support for adding a ethertype based filter rule on VSI and describe it in a very long run-on sentence. :-) Bruce cleans up static analysis warnings by removing a local variable initialization that is not needed. Brett makes the allocate/deallocate more consistent in all the driver flows for VSI q_vectors. In addition, makes setting/getting coalesce settings more consistent throughout the driver. ==================== Signed-off-by: -

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2019-05-04 This series contains updates to i40e only. Grzegorz fixes a bug with promiscuous mode not being kept when the VF switched to a new VLAN. Fixed a typo in the link mode code, by using the correct define. Fixed truncation issue, which changed an function argument to a smaller value that should have been a larger value. Aleksandr adds support for new x710 devices and the speeds they support. Sergey adds a check for the number of vectors against the number of MSIx vectors to ensure one does not exceed the other. Martyna adds additional input validation on VF messages handled by the PF. Fixed potential memory leaks in the driver where the error paths were not freeing allocated memory. Maciej reverts the double ShadowRAM checksum calculation change because issues were found in the NVM downgrade situation. Gustavo Silva changes the i40e driver to use struct_size() in kzalloc() calls, to avoid type mistakes. ==================== Signed-off-by: -

Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes, in particular in the context in which this code is being used. So, replace code of the following form: sizeof(struct xt_hashlimit_htable) + sizeof(struct hlist_head) * size with: struct_size(hinfo, hash, size) This code was detected with the help of Coccinelle.
