Vivien Didelot says: ==================== net: dsa: tagger simplification This series clarifies the hot path, removes the labels in tagging implementations, and frees the original SKB in the xmit caller. Changes in v3: - drop removal of usused rcv arguments because they will be used later - include the new ksz tagging implementation - add reviewers' tags Changes in v2: - do not remove tagger function copies - document hot path requirements - make netdev_uses_dsa simpler - add reviewers' tags ==================== Signed-off-by: -

As of a86d8bec ("net: dsa: Factor bottom tag receive functions"), the rcv caller frees the original SKB in case or error. Be symmetric with that and make the xmit caller do the same. At the same time, fix the checkpatch NULL comparison check: CHECK: Comparison to NULL could be written "!nskb" #208: FILE: net/dsa/tag_trailer.c:35: + if (nskb == NULL) Signed-off-by:

Many rcv functions from net/dsa/tag_*.c have a useless out_drop goto label which simply returns NULL. Kill it in favor of the obvious. Reviewed-by:

Since dev->dsa_ptr is a pointer to a dsa_switch_tree, there is no need to have another inline helper just to check rcv. Remove dsa_uses_tagged_protocol and check dsa_ptr && dsa_ptr->rcv together at the same time. Reviewed-by:

dsa_ptr is not a void pointer anymore since Nov 2011, as of cf50dcc2 ("dsa: Change dsa_uses_{dsa, trailer}_tags() into inline functions"), but an explicit dsa_switch_tree pointer, thus remove the (void *) cast. Reviewed-by:

Corentin Labbe says: ==================== net-next: stmmac: add dwmac-sun8i ethernet driver This patch series add the driver for dwmac-sun8i which handle the Ethernet MAC present on Allwinner H3/H5/A83T/A64 SoCs. This driver is the continuation of the sun8i-emac driver. During the development, it appeared that in fact the hardware was a modified version of some dwmac. So the driver is now written as a glue driver for stmmac. It supports 10/100/1000 Mbit/s speed with half/full duplex. It can use an internal PHY (MII 10/100) or an external PHY via RGMII/RMII. This patch series enable the driver only for the H3/A64/H5 SoC since A83T doesn't have the necessary clocks present in mainline. The driver have been tested on the following boards: - H3 Orange PI PC, BananaPI-M2+ - A64 Pine64, BananaPi-M64 - A83T BananaPI-M3 The first two patchs are some mandatory changes for letting dwmac-sun8i be used. The following three patchs add the driver and its documentation. The remaining are DT patch enabling it. Regards Corentin Labbe Changes since v5: - Added DT patch for NanoPi neo - Use the new adjust_link variables (speedxxx/speedmask) - Made the timeout of readl_poll_timeout from 10 to 100ms - Fix sun8i_unpower_phy that could be called twice - Replace phy by phy-handle in doc/dwmac-sun8i.txt Changes since v4: - Re-ordered by alphabetical order some DT nodes - Simplified power/unpower_phy functions by testing the use of internal_phy - Added a patch for adding dwmac-sun8i to arm64 defconfig - Fix a typo in sun50i-a64-system-controller (wrongly used sun8i) - Reworked uc/mc filter address setting Changes since v3: - Renamed tx-delay/rx-delay to tx-delay-ps/rx-delay-ps - fix syscon compatible example - Changed parameter type for setup() function - Dropped some DT patchs for boards which I could not test further Changes since v2: - corrected order of syscon compatible - added compatible = "ethernet-phy-ieee802.3-c22 to PHY - added set_mac function Changes since v1: - added TX/RX delay units - splitted syscon documentation in its own patch - regulator is now disabled after clk_prepare_enable(gmac->tx_clk) error - Fixed a memory leak on mac_device_info - Use now generic pin config for all DT stuff - CONFIG_DWMAC_SUN8I is now set to y in defconfigs ==================== Signed-off-by: -

The dwmac-sun8i is an Ethernet MAC that supports 10/100/1000 Mbit connections. It is very similar to the device found in the Allwinner H3, but lacks the internal 100 Mbit PHY and its associated control bits. This adds the necessary bits to the Allwinner A64 SoC .dtsi, but keeps it disabled at this level. Signed-off-by:

Add callback to the ethtool flash_device op. This callback uses the mlxfw module to flash the new firmware file to the device. As the firmware flash process takes about 20 seconds and ethtool takes the rtnl lock during the flash_device callback, release the rtnl lock at the beginning of the flash process and take it again before leaving the callback. This way, the rtnl is not held during the process. To make sure the device does not get deleted during the flash process, take a reference to it before releasing the rtnl lock. Signed-off-by:

Yuval Mintz says: ==================== qed: Status block changes The device maintains a CAM mapping of the internal status blocks and the various PF/VF MSI-x vector mappings. During initialization, the driver reads the HW memory and constructs a shadow SW implementation which it would later use for manipulation of interrupts. E.g., when enabling VFs and setting their MSI-x tables. The driver currently has some very strict assumptions on the order the entries are placed in the CAM. Specifically, it assumes that all entries belonging to a PF would be consecutive and in-order in the CAM, and that the VF entries would then follow. But there's no actual HW constraint enforcing this assumption [although management firmware does set it accordingly to same assumption initially]. Since the CAM is re-configurable, there are now SW flows employeed by other OSes that might cause the assumption to be invalid. Such flows allow the PF to forfeit some of it's available interrupts in favor of its VFs or vice versa. While those are not employeed today by qed, we want to relax the assumptions as much as we can - both to allow functionality after PDA as well as allowing future compatibility where the driver would be loaded after a newer one has 'dirtied' the CAM configuration. In addition to patches meant for the above relaxation, the series also contains various cleanups & refactoring for interrupt logic [most of which is !semantic]. ==================== Signed-off-by: -

The IGU CAM contains an assocaition between hardware SBs and interrupt lines, and it can be dynamically configured to allow more interrupts in one entity over another, specifically for Re-distibution of SBs between a PF and its child VFs. While we don't yet use this functionality, there are other clients that do and as such its possible the information passed from management firmware during initialization in regard to the possible number of SBs doesn't accurately reflect the current HW configuration. The following changes are going to apply to the driver init sequence: a. PF is going to re-configure all entries belonging to itself and its child VFs in IGU CAM based on the management firmware info regarding the number of SBs that are supposed to exist there. b. PF is going to stop using the SB resource [management firmware provided information] for anything but the initialization. Instead, it would use the live-time counters it maintains for the numbers.

A PF today holds 2 different arrays - one holding information about the HW configuration and one holding information about the SBs that are used by the protocol drivers. These arrays aren't really connected - e.g., protocol driver initializing a given SB would not mark the same SB as occupied in the HW shadow array. Move into a single array [at least for PFs] - hold the mapping of the driver-protocol SBs on the HW entry which they configure. Signed-off-by:

Current code assumes there's a known layout for SBs in the IGU, where all the SBs of a single entity would be laid in consecutive order of vectors. While the assumption is still kept by management firmware, we already have the necessary information to eliminate it, so no reason to keep it in code. Signed-off-by:
