Currently, there are three eswitch modes, none, legacy and switchdev. None is the default mode. Remove redundant none mode as eswitch mode should always be either legacy mode or switchdev mode. With this patch, there are two behavior changes: 1. Legacy becomes the default mode. When querying eswitch mode using devlink, a valid mode is always returned. 2. When disabling sriov, the eswitch mode will not change, only vfs are unloaded. Signed-off-by:

Eswitch vport acl namespace is needed when loading vfs. There is no need to free and reallocate it when switching eswitch mode. Introduce flag to indicate if it is created or not. When needed, create it. Only free it when the driver is unloaded or in bare metal mode. Signed-off-by:

Smatch complains about this function: drivers/net/ethernet/mellanox/mlx5/core/eswitch.c:2000 mlx5_esw_unlock() warn: inconsistent returns '&esw->mode_lock'. Before commit ec2fa47d ("net/mlx5: Lag, use lag lock") there used to be a matching mlx5_esw_lock() function and the lock and unlock functions were symmetric. But now we take the lock unconditionally and must unlock unconditionally as well. As near as I can tell this is dead code and can just be deleted.

Arun Ramadoss says: ==================== net: dsa: microchip: DSA Driver support for LAN937x LAN937x is a Multi-Port 100BASE-T1 Ethernet Physical Layer switch compliant with the IEEE 802.3bw-2015 specification. The device provides 100 Mbit/s transmit and receive capability over a single Unshielded Twisted Pair (UTP) cable. LAN937x is successive revision of KSZ series switch. This series of patches provide the DSA driver support for Microchip LAN937X switch through MII/RMII interface. The RGMII interface support will be added in the follow up series. LAN937x uses the most of functionality of KSZ9477. The LAN937x switch series family consists of following SKUs: LAN9370: - 4 T1 Phys - 1 RGMII port LAN9371: - 3 T1 Phys & 1 TX Phy - 2 RGMII ports LAN9372: - 5 T1 Phys & 1 TX Phy - 2 RGMII ports LAN9373: - 5 T1 Phys - 2 RGMII - 1 SGMII port LAN9374: - 6 T1 Phys - 2 RGMII ports Changes in v15: - fixed compilation issue. - Updated the phylink_mac_link_up to check only for 10/100/1000 speed. Changes in v14: - Updated the patch series to latest ksz code refactoring. - RGMII register configuration is removed from the series. It will be added in the follow up patch series. Changes in v13: - Fixed the compilation issue in patch 5 and 6 Changes in v12: - Removed the reduntant spi indirect enable in lan937x_init - Used the ksz_port_stp_state_set function - Apply rgmii internal delay only if it is rgmii port - Set the bit for 100baseTx in phylink_get_caps - Moved the ethtool related API from patch 5 to 7 - Moved lan_alu_entry struct in lan937x_dev.h from patch 5 to 9 - Moved lan_vlan_entry in lan937x_dev.h from patch 5 to 10 - Used the ksz_get_stats64 function for get_stats64 hook - Splitted the patch 5. one for port configuration, spi driver, phy read & write and mtu configuration. - Updated the indentation in ethernet-controller.yaml - lan937x.yaml: Removed the blank lines, updated the ethernet handle to macb0. Added the rgmii internal delay only for the ports. Changes in v11: - Tagged as RFC to get the feedback for the subpatches 1/10, 5/10 and 6/10 Changes in v10: - dsa.yaml: dropped moving mdio properties to dsa.yaml as per the feedback https://patchwork.kernel.org/project/netdevbpf/patch/20220318085540.281721-3-prasanna.vengateshan@microchip.com/#24787466 - microchip,lan937x.yaml: Naming convention changes in the example - lan937x_main.c: Moving configurations from lan937x_reset_switch() to setup() - lan937x_main.c: helper function has been introduced for lan937x_internal_phy_read & write - lan937x_dev.h: lan_alu_struct struct data type changes - lan937x_main.c: lan937x_get_stats64 make non blocking - lan937x_main.c: modified lan937x_port_mirror_add to include extack Changes in v9: - lan937x_main.c: of_node_put() correction in lan937x_parse_dt_rgmii_delay - lan937x_dev.c: removed the interface checks from lan937x_apply_rgmii_delay. - changes in ethernet-controller.yaml and dsa.yaml Changes in v8: - lan937x_dev.c: fixed lan937x_r_mib_pkt warning in the sub patches - lan937x_main.c: phylink_autoneg_inband() check removed in lan937x_phylink_mac_link_up() - lan937x_main.c: made legacy_pre_march2020 = false as this is non-legacy driver and indentation correction in lan937x_phylink_mac_link_up() - removed unnecessary parenthesis in lan937x_get_strings() Changes in v7: - microchip,lan937x.yaml: *-internal-delay-ps enum values & commit messages corrections - lan937x_main.c: removed phylink_validate() and added phylink_get_caps() - lan937x_main.c: added support for ethtool standard stats (get_eth_*_stats and get_stats64) - lan937x_main.c: removed unnecessary PVID read from lan937x_port_vlan_del() - integrated the changes of ksz9477 multi bridging support to lan937x dev and tested both multi bridging and STP - lan937x_port_vlan_del - dummy pvid read removed Changes in v6: - microchip_t1.c: There was new merge done in the net-next tree for microchip_1.c after the v5 submission.

Basic DSA driver support for lan937x and the device will be configured through SPI interface. It adds the lan937x_dev_ops in ksz_common.c file and tries to reuse the functionality of ksz9477 series switch. drivers/net/dsa/microchip/ path is already part of MAINTAINERS & the new files come under this path. Hence no update needed to the MAINTAINERS Signed-off-by:

The ksz9477 and lan937x has few difference in the static and reserved table register 0x041C. For the ksz9477 if the bit 0 is 1 - read operation and 0 - write operation. But for lan937x bit 1:0 used for selecting the read/write operation, 01 - write and 10 - read. To use ksz9477 mdb add/del and enable_stp_addr for the lan937x, masks & shifts are introduced for ksz9477 & lan937x in ksz_common.c. Then updated the function with masks & shifts based on the switch instead of hard coding it. Signed-off-by:

As stated by Russel King, miic_config() can be called as a result of ethtool setting the configuration while the link is already up. Since the speed is also set in this function, it could potentially modify the current speed that is set. This will only happen if there is no PHY present and we aren't using fixed-link mode. Handle that by storing the current interface mode in the miic_port structure and update the speed only if the interface mode is going to be changed. Signed-off-by:
