2022-03-10can: gs_usb: add quirk for CANtact Pro overlapping GS_USB_BREQ valueMarc Kleine-Budde
For the GS_USB_BREQ_DATA_BITTIMING USB control message the CANtact Pro firmware uses a request value, which is already used by the candleLight firmware for a different purpose (GS_USB_BREQ_GET_USER_ID). This patch adds a quirk to use the CANtact Pro's value for the GS_USB_BREQ_DATA_BITTIMING USB control message instead of the official one.

2022-03-10can: gs_usb: add usb quirk for NXP LPC546xx controllersPeter Fink
Introduce a workaround for a NXP chip errata on LPC546xx controllers (Errata sheet LPC546xx / USB.15). According to the document corruption can occur when the following conditions are met: * A TX (IN) transfer happens after a RX (OUT) transfer. * The RX (OUT) transfer length is 4 + N * 16 (N >= 0) bytes. Even though the struct gs_host_frame has a size of 76 bytes for a FD frame, which does not apply to the above rule, corruption could be seen. Adding a dummy byte to break the second condition also on transfer lengths with 4 + N * 8 bytes reliably circumvents USB transfer data corruption. The firmware can now request this quirk by setting GS_CAN_FEATURE_REQ_USB_QUIRK_LPC546XX.

2022-03-10can: gs_usb: add CAN-FD supportPeter Fink
CANtact Pro from Linklayer is the first gs_usb compatible device supporting CAN-FD with a different HW and re-written candlelight FW. Support for CAN-FD is indicated by the device setting the GS_CAN_FEATURE_FD flag. CAN-FD support is requested by the driver with the GS_CAN_MODE_FD flag. The CAN-FD specific data bit timing parameters are set with the GS_USB_BREQ_DATA_BITTIMING control message. This patch is based on the Eric Evenchick's gs_usb_fd driver (which itself is a fork of gs_usb). The gs_usb_fd code base was reintegrated into the gs_usb driver, and reworked to not break the existing classical-CAN only hardware.

Modify struct gs_host_frame to make use of a union and DECLARE_FLEX_ARRAY to be able to store different data (lengths), which will be added in later commits. Store the gs_host_frame length in TX direction (host -> device) in struct gs_can::hf_size_tx and RX direction (device -> host) in struct gs_usb::hf_size_rx so it must be calculated only once.

calling es58x_check_msg_len() Function es58x_fd_rx_event() invokes the es58x_check_msg_len() macro: | ret = es58x_check_msg_len(es58x_dev->dev, *rx_event_msg, msg_len); While doing so, it dereferences an uninitialized variable: *rx_event_msg. This is actually harmless because es58x_check_msg_len() only uses preprocessor macros (sizeof() and __stringify()) on *rx_event_msg. c.f. [1]. Nonetheless, this pattern is confusing so the lines are reordered to make sure that rx_event_msg is correctly initialized.

2022-03-10vxcan: enable local echo for sent CAN framesOliver Hartkopp
The vxcan driver provides a pair of virtual CAN interfaces to exchange CAN traffic between different namespaces - analogue to veth. In opposite to the vcan driver the local sent CAN traffic on this interface is not echo'ed back but only sent to the remote peer. This is unusual and can be easily fixed by removing IFF_ECHO from the netdevice flags that are set for vxcan interfaces by default at startup. Without IFF_ECHO set on driver level, the local sent CAN frames are echo'ed in af_can.c in can_send(). This patch makes vxcan interfaces adopt the same local echo behavior and procedures as known from the vcan interfaces.

2022-03-10vxcan: remove sk reference in peer skbOliver Hartkopp
With can_create_echo_skb() the skb which is forwarded to the peer CAN interface shares the sk pointer from the originating socket. This makes the CAN frame show up in the peer namespace as a TX packet. With the use of skb_clone() analogue to the handling in gw.c the peer skb gets a new start in the peer namespace and correctly appears as a RX packet.

2022-03-09e1000e: Print PHY register address when MDI read/write failsChen Yu
There is occasional suspend error from e1000e which blocks the system from further suspending. And the issue was found on a WhiskeyLake-U platform with I219-V: [ 20.078957] PM: pci_pm_suspend(): e1000e_pm_suspend+0x0/0x780 [e1000e] returns -2 [ 20.078970] PM: dpm_run_callback(): pci_pm_suspend+0x0/0x170 returns -2 [ 20.078974] e1000e 0000:00:1f.6: PM: pci_pm_suspend+0x0/0x170 returned -2 after 371012 usecs [ 20.078978] e1000e 0000:00:1f.6: PM: failed to suspend async: error -2 According to the code flow, this might be caused by broken MDI read/write to PHY registers. However currently the code does not tell us which register is broken. Thus enhance the debug information to print the offender PHY register. So the next the issue is reproduced, this information could be used for narrow down.

2022-03-09net: dsa: microchip: ksz9477: implement MTU configurationOleksij Rempel
This chips supports two ways to configure max MTU size: - by setting SW_LEGAL_PACKET_DISABLE bit: if this bit is 0 allowed packed size will be between 64 and bytes 1518. If this bit is 1, it will accept packets up to 2000 bytes. - by setting SW_JUMBO_PACKET bit. If this bit is set, the chip will ignore SW_LEGAL_PACKET_DISABLE value and use REG_SW_MTU__2 register to configure MTU size. Current driver has disabled SW_JUMBO_PACKET bit and activates SW_LEGAL_PACKET_DISABLE. So the switch will pass all packets up to 2000 without any way to configure it. By providing port_change_mtu we are switch to SW_JUMBO_PACKET way and will be able to configure MTU up to ~9000.

Except for several differences, the STEv2 is identical to STEv1, so for most callbacks the STEv2 context struct will call STEv1 functions.

These registers mapping has changed in ConnectX-7, so the renaming allows to keep track of their mapping better.

2022-03-09net/mlx5: DR, Align mlx5dv_dr API vport action with FW behaviorShun Hao
This aligns the behavior with FW when creating an FDB rule with wire vport destination but no source port matching. Until now such rules would fail on internal DR RX rule creation since the source and destination are the wire vport. The new behavior is the same as done on FW steering, if destination is wire, we will create both TX and RX rules, but the RX packet coming from wire will be dropped due to loopback not supported.
