net: Distributed Switch Architecture protocol support Distributed Switch Architecture is a protocol for managing hardware switch chips. It consists of a set of MII management registers and commands to configure the switch, and an ethernet header format to signal which of the ports of the switch a packet was received from or is intended to be sent to. The switches that this driver supports are typically embedded in access points and routers, and a typical setup with a DSA switch looks something like this: +-----------+ +-----------+ | | RGMII | | | +-------+ +------ 1000baseT MDI ("WAN") | | | 6-port +------ 1000baseT MDI ("LAN1") | CPU | | ethernet +------ 1000baseT MDI ("LAN2") | |MIImgmt| switch +------ 1000baseT MDI ("LAN3") | +-------+ w/5 PHYs +------ 1000baseT MDI ("LAN4") | | | | +-----------+ +-----------+ The switch driver presents each port on the switch as a separate network interface to Linux, polls the switch to maintain software link state of those ports, forwards MII management interface accesses to those network interfaces (e.g. as done by ethtool) to the switch, and exposes the switch's hardware statistics counters via the appropriate Linux kernel interfaces. This initial patch supports the MII management interface register layout of the Marvell 88E6123, 88E6161 and 88E6165 switch chips, and supports the "Ethertype DSA" packet tagging format. (There is no officially registered ethertype for the Ethertype DSA packet format, so we just grab a random one. The ethertype to use is programmed into the switch, and the switch driver uses the value of ETH_P_EDSA for this, so this define can be changed at any time in the future if the one we chose is allocated to another protocol or if Ethertype DSA gets its own officially registered ethertype, and everything will continue to work.)

/* The switch ADDR[4:1] configuration pins define the chip SMI device address
* (ADDR[0] is always zero, thus only even SMI addresses can be strapped).
*
* When ADDR is all zero, the chip uses Single-chip Addressing Mode, assuming it
* is the only device connected to the SMI master. In this mode it responds to
* all 32 possible SMI addresses, and thus maps directly the internal devices.
*
* When ADDR is non-zero, the chip uses Multi-chip Addressing Mode, allowing
* multiple devices to share the SMI interface. In this mode it responds to only
* 2 registers, used to indirectly access the internal SMI devices.

The switches that this driver supports are typically embedded in access points and routers, and a typical setup with a DSA switch looks something like this: +-----------+ +-----------+ | | RGMII | | | +-------+ +------ 1000baseT MDI ("WAN") | | | 6-port +------ 1000baseT MDI ("LAN1") | CPU | | ethernet +------ 1000baseT MDI ("LAN2") | |MIImgmt| switch +------ 1000baseT MDI ("LAN3") | +-------+ w/5 PHYs +------ 1000baseT MDI ("LAN4") | | | | +-----------+ +-----------+ The switch driver presents each port on the switch as a separate network interface to Linux, polls the switch to maintain software link state of those ports, forwards MII management interface accesses to those network interfaces (e.g. as done by ethtool) to the switch, and exposes the switch's hardware statistics counters via the appropriate Linux kernel interfaces. This initial patch supports the MII management interface register layout of the Marvell 88E6123, 88E6161 and 88E6165 switch chips, and supports the "Ethertype DSA" packet tagging format. (There is no officially registered ethertype for the Ethertype DSA packet format, so we just grab a random one. The ethertype to use is programmed into the switch, and the switch driver uses the value of ETH_P_EDSA for this, so this define can be changed at any time in the future if the one we chose is allocated to another protocol or if Ethertype DSA gets its own officially registered ethertype, and everything will continue to work.)

net: dsa: mv88e6xxx: Set the CMODE for mv88e6390 ports 9 & 10 Unlike most ports, ports 9 and 10 of the 6390X family have configurable PHY modes. Set the mode as part of adjust_link(). Ordering is important, because the SERDES interfaces connected to ports 9 and 10 can be split and assigned to other ports. The CMODE has to be correctly set before the SERDES interface on another port can be configured. Such configuration is likely to be performed in port_enable() and port_disabled(), called on slave_open() and slave_close(). The simple case is port 9 and 10 are used for 'CPU' or 'DSA'. In this case, the CMODE is set via a phy-mode in dsa_cpu_dsa_setup(), which is called early in the switch setup. When ports 9 or 10 are used as user ports, and have a fixed-phy, when the fixed fixed-phy is attached, dsa_slave_adjust_link() is called, which results in the adjust_link function being called, setting the cmode. The port_enable() will for other ports will be called much later. When ports 9 or 10 are used as user ports and have a real phy attached which does not use all the available SERDES interface, e.g. a 1Gbps SGMII, there is currently no mechanism in place to set the CMODE of the port from software. It must be hoped the stripping resistors are correct. At the same time, add a function to get the cmode. This will be needed when configuring the SERDES interfaces.

net: Distributed Switch Architecture protocol support Distributed Switch Architecture is a protocol for managing hardware switch chips. It consists of a set of MII management registers and commands to configure the switch, and an ethernet header format to signal which of the ports of the switch a packet was received from or is intended to be sent to. The switches that this driver supports are typically embedded in access points and routers, and a typical setup with a DSA switch looks something like this: +-----------+ +-----------+ | | RGMII | | | +-------+ +------ 1000baseT MDI ("WAN") | | | 6-port +------ 1000baseT MDI ("LAN1") | CPU | | ethernet +------ 1000baseT MDI ("LAN2") | |MIImgmt| switch +------ 1000baseT MDI ("LAN3") | +-------+ w/5 PHYs +------ 1000baseT MDI ("LAN4") | | | | +-----------+ +-----------+ The switch driver presents each port on the switch as a separate network interface to Linux, polls the switch to maintain software link state of those ports, forwards MII management interface accesses to those network interfaces (e.g. as done by ethtool) to the switch, and exposes the switch's hardware statistics counters via the appropriate Linux kernel interfaces. This initial patch supports the MII management interface register layout of the Marvell 88E6123, 88E6161 and 88E6165 switch chips, and supports the "Ethertype DSA" packet tagging format. (There is no officially registered ethertype for the Ethertype DSA packet format, so we just grab a random one. The ethertype to use is programmed into the switch, and the switch driver uses the value of ETH_P_EDSA for this, so this define can be changed at any time in the future if the one we chose is allocated to another protocol or if Ethertype DSA gets its own officially registered ethertype, and everything will continue to work.)

net: Distributed Switch Architecture protocol support Distributed Switch Architecture is a protocol for managing hardware switch chips. It consists of a set of MII management registers and commands to configure the switch, and an ethernet header format to signal which of the ports of the switch a packet was received from or is intended to be sent to. The switches that this driver supports are typically embedded in access points and routers, and a typical setup with a DSA switch looks something like this: +-----------+ +-----------+ | | RGMII | | | +-------+ +------ 1000baseT MDI ("WAN") | | | 6-port +------ 1000baseT MDI ("LAN1") | CPU | | ethernet +------ 1000baseT MDI ("LAN2") | |MIImgmt| switch +------ 1000baseT MDI ("LAN3") | +-------+ w/5 PHYs +------ 1000baseT MDI ("LAN4") | | | | +-----------+ +-----------+ The switch driver presents each port on the switch as a separate network interface to Linux, polls the switch to maintain software link state of those ports, forwards MII management interface accesses to those network interfaces (e.g. as done by ethtool) to the switch, and exposes the switch's hardware statistics counters via the appropriate Linux kernel interfaces. This initial patch supports the MII management interface register layout of the Marvell 88E6123, 88E6161 and 88E6165 switch chips, and supports the "Ethertype DSA" packet tagging format. (There is no officially registered ethertype for the Ethertype DSA packet format, so we just grab a random one. The ethertype to use is programmed into the switch, and the switch driver uses the value of ETH_P_EDSA for this, so this define can be changed at any time in the future if the one we chose is allocated to another protocol or if Ethertype DSA gets its own officially registered ethertype, and everything will continue to work.)

net: dsa: mv88e6xxx: fix software VLAN deletion The current bridge code calls switchdev_port_obj_del on a VLAN port even if the corresponding switchdev_port_obj_add call returned -EOPNOTSUPP. If the DSA driver doesn't return -EOPNOTSUPP for a software port VLAN in its port_vlan_del function, the VLAN is not deleted. Unbridging the port also generates a stack trace for the same reason. This can be quickly tested on a VLAN filtering enabled system with: # brctl addbr br0 # brctl addif br0 lan0 # brctl addbr br1 # brctl addif br1 lan1 # brctl delif br1 lan1 Both bridges have a default default_pvid set to 1. lan0 uses the hardware VLAN 1 while lan1 falls back to the software VLAN 1. Unbridging lan1 does not delete its software VLAN, and thus generates the following stack trace: [ 2991.681705] device lan1 left promiscuous mode [ 2991.686237] br1: port 1(lan1) entered disabled state [ 2991.725094] ------------[ cut here ]------------ [ 2991.729761] WARNING: CPU: 0 PID: 869 at net/bridge/br_vlan.c:314 __vlan_group_free+0x4c/0x50() [ 2991.738437] Modules linked in: [ 2991.741546] CPU: 0 PID: 869 Comm: ip Not tainted 4.4.0 #16 [ 2991.747039] Hardware name: Freescale Vybrid VF5xx/VF6xx (Device Tree) [ 2991.753511] Backtrace: [ 2991.756008] [<80014450>] (dump_backtrace) from [<8001469c>] (show_stack+0x20/0x24) [ 2991.763604] r6:80512644 r5:00000009 r4:00000000 r3:00000000 [ 2991.769343] [<8001467c>] (show_stack) from [<80268e44>] (dump_stack+0x24/0x28) [ 2991.776618] [<80268e20>] (dump_stack) from [<80025568>] (warn_slowpath_common+0x98/0xc4) [ 2991.784750] [<800254d0>] (warn_slowpath_common) from [<80025650>] (warn_slowpath_null+0x2c/0x34) [ 2991.793557] r8:00000000 r7:9f786a8c r6:9f76c440 r5:9f786a00 r4:9f68ac00 [ 2991.800366] [<80025624>] (warn_slowpath_null) from [<80512644>] (__vlan_group_free+0x4c/0x50) [ 2991.808946] [<805125f8>] (__vlan_group_free) from [<80514488>] (nbp_vlan_flush+0x44/0x68) [ 2991.817147] r4:9f68ac00 r3:9ec70000 [ 2991.820772] [<80514444>] (nbp_vlan_flush) from [<80506f08>] (del_nbp+0xac/0x130) [ 2991.828201] r5:9f56f800 r4:9f786a00 [ 2991.831841] [<80506e5c>] (del_nbp) from [<8050774c>] (br_del_if+0x40/0xbc) [ 2991.838724] r7:80590f68 r6:00000000 r5:9ec71c38 r4:9f76c440 [ 2991.844475] [<8050770c>] (br_del_if) from [<80503dc0>] (br_del_slave+0x1c/0x20) [ 2991.851802] r5:9ec71c38 r4:9f56f800 [ 2991.855428] [<80503da4>] (br_del_slave) from [<80484a34>] (do_setlink+0x324/0x7b8) [ 2991.863043] [<80484710>] (do_setlink) from [<80485e90>] (rtnl_newlink+0x508/0x6f4) [ 2991.870616] r10:00000000 r9:9ec71ba8 r8:00000000 r7:00000000 r6:9f6b0400 r5:9f56f800 [ 2991.878548] r4:8076278c [ 2991.881110] [<80485988>] (rtnl_newlink) from [<80484048>] (rtnetlink_rcv_msg+0x18c/0x22c) [ 2991.889315] r10:9f7d4e40 r9:00000000 r8:00000000 r7:00000000 r6:9f7d4e40 r5:9f6b0400 [ 2991.897250] r4:00000000 [ 2991.899814] [<80483ebc>] (rtnetlink_rcv_msg) from [<80497c74>] (netlink_rcv_skb+0xb0/0xcc) [ 2991.908104] r8:00000000 r7:9f7d4e40 r6:9f7d4e40 r5:80483ebc r4:9f6b0400 [ 2991.914928] [<80497bc4>] (netlink_rcv_skb) from [<80483eb4>] (rtnetlink_rcv+0x34/0x3c) [ 2991.922874] r6:9f5ea000 r5:00000028 r4:9f7d4e40 r3:80483e80 [ 2991.928622] [<80483e80>] (rtnetlink_rcv) from [<80497604>] (netlink_unicast+0x180/0x200) [ 2991.936742] r4:9f4edc00 r3:80483e80 [ 2991.940362] [<80497484>] (netlink_unicast) from [<80497a88>] (netlink_sendmsg+0x33c/0x350) [ 2991.948648] r8:00000000 r7:00000028 r6:00000000 r5:9f5ea000 r4:9ec71f4c [ 2991.955481] [<8049774c>] (netlink_sendmsg) from [<80457ff0>] (sock_sendmsg+0x24/0x34) [ 2991.963342] r10:00000000 r9:9ec71e28 r8:00000000 r7:9f1e2140 r6:00000000 r5:00000000 [ 2991.971276] r4:9ec71f4c [ 2991.973849] [<80457fcc>] (sock_sendmsg) from [<80458af0>] (___sys_sendmsg+0x1fc/0x204) [ 2991.981809] [<804588f4>] (___sys_sendmsg) from [<804598d0>] (__sys_sendmsg+0x4c/0x7c) [ 2991.989640] r10:00000000 r9:9ec70000 r8:80010824 r7:00000128 r6:7ee946c4 r5:00000000 [ 2991.997572] r4:9f1e2140 [ 2992.000128] [<80459884>] (__sys_sendmsg) from [<80459918>] (SyS_sendmsg+0x18/0x1c) [ 2992.007725] r6:00000000 r5:7ee9c7b8 r4:7ee946e0 [ 2992.012430] [<80459900>] (SyS_sendmsg) from [<80010660>] (ret_fast_syscall+0x0/0x3c) [ 2992.020182] ---[ end trace 5d4bc29f4da04280 ]--- To fix this, return -EOPNOTSUPP in _mv88e6xxx_port_vlan_del instead of -ENOENT if the hardware VLAN doesn't exist or the port is not a member.

net: dsa: mv88e6xxx: Set the CMODE for mv88e6390 ports 9 & 10 Unlike most ports, ports 9 and 10 of the 6390X family have configurable PHY modes. Set the mode as part of adjust_link(). Ordering is important, because the SERDES interfaces connected to ports 9 and 10 can be split and assigned to other ports. The CMODE has to be correctly set before the SERDES interface on another port can be configured. Such configuration is likely to be performed in port_enable() and port_disabled(), called on slave_open() and slave_close(). The simple case is port 9 and 10 are used for 'CPU' or 'DSA'. In this case, the CMODE is set via a phy-mode in dsa_cpu_dsa_setup(), which is called early in the switch setup. When ports 9 or 10 are used as user ports, and have a fixed-phy, when the fixed fixed-phy is attached, dsa_slave_adjust_link() is called, which results in the adjust_link function being called, setting the cmode. The port_enable() will for other ports will be called much later. When ports 9 or 10 are used as user ports and have a real phy attached which does not use all the available SERDES interface, e.g. a 1Gbps SGMII, there is currently no mechanism in place to set the CMODE of the port from software. It must be hoped the stripping resistors are correct. At the same time, add a function to get the cmode. This will be needed when configuring the SERDES interfaces.

net: dsa: mv88e6xxx: Set the CMODE for mv88e6390 ports 9 & 10 Unlike most ports, ports 9 and 10 of the 6390X family have configurable PHY modes. Set the mode as part of adjust_link(). Ordering is important, because the SERDES interfaces connected to ports 9 and 10 can be split and assigned to other ports. The CMODE has to be correctly set before the SERDES interface on another port can be configured. Such configuration is likely to be performed in port_enable() and port_disabled(), called on slave_open() and slave_close(). The simple case is port 9 and 10 are used for 'CPU' or 'DSA'. In this case, the CMODE is set via a phy-mode in dsa_cpu_dsa_setup(), which is called early in the switch setup. When ports 9 or 10 are used as user ports, and have a fixed-phy, when the fixed fixed-phy is attached, dsa_slave_adjust_link() is called, which results in the adjust_link function being called, setting the cmode. The port_enable() will for other ports will be called much later. When ports 9 or 10 are used as user ports and have a real phy attached which does not use all the available SERDES interface, e.g. a 1Gbps SGMII, there is currently no mechanism in place to set the CMODE of the port from software. It must be hoped the stripping resistors are correct. At the same time, add a function to get the cmode. This will be needed when configuring the SERDES interfaces.
