2022-03-11net/mlx5e: Remove overzealous validations in netlink EEPROM queryGal Pressman1-23/+0
Unlike the legacy EEPROM callbacks, when using the netlink EEPROM query (get_module_eeprom_by_page) the driver should not try to validate the query parameters, but just perform the read requested by the userspace. Recent discussion in the mailing list: https://lore.kernel.org/netdev/20220120093051.70845141@kicinski-fedora-PC1C0HJN.hsd1.ca.comcast.net/ Signed-off-by: Gal Pressman <gal@nvidia.com> Reviewed-by: Ido Schimmel <idosch@nvidia.com> Reviewed-by: Maxim Mikityanskiy <maximmi@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com>

2022-03-11net/mlx5: CT: Create smfs dr matchers dynamicallyPaul Blakey1-88/+94
SMFS dr matchers are processed sequentially in hardware according to their priorities, and not skipped if empty. Currently, smfs ct fs creates four predefined dr matchers per ct table (ct/ct nat) with hardcoded priority. Compared to dmfs ct fs using autogroups, this might cause additional hops in fastpath for traffic patterns that match later priorties, even if previous priorites are empty, e.g user only using ipv6 UDP traffic will have additional 3 hops. Create the matchers dynamically, using the highest priority available, on first rule usage, and remove them on last usage.

2022-03-11net/mlx5: CT: Add software steering ct flow steering providerPaul Blakey6-7/+435
fs_core layer adds extra book keeping that is either unneeded for CT, or unused by the underlying software steering, such as allocating FTEs and FTE ids, saving the match key and mask, and autogroups management. On top of that, direct steering has a translation layer (fs_dr) from PRM commands to direct steering objects, for example, creating temporary dr_action objects. This has a performance impact when dealing with CT high insertion rate. To use direct steering (smfs) directly for ct, add a tc ct fs smfs implementation. Instead of dmfs autogroups, smfs ct fs uses one of 4 predefined dr matchers in CT and CT-NAT tables, for each combination of tuple ethertype (ipv4/ipv6), and tuple ip_proto (udp/tcp) that is currently used by nf flow table flow offload. At rule insertions, validate the flow rule fits one of the predfined matcher, and insert to it. To fill the dr_actions of the rule efficiently, create the fwd to post_ct tbl dr_action at fs init, the count dr_action at counter creation, and re-use the already pre-allocated modify header dr_action.

2022-03-11net/mlx5: CT: Introduce a platform for multiple flow steering providersPaul Blakey4-4/+119
Currently, fs_core layer provides flow steering services to the driver including: autogroups, allocating FTEs (flow table entries) and FTE ids, and support of fte action modification. If then software steering is configured, rule insertion will go through a translation layer from firmware buffers to software steering objects (see fs_dr.c). The connection tracking table is a system table that is not directly controlled by the user and is a very high scale table. These fs_core services introduces an overhead that may be optimized by using software steering API directly. Introduce ct flow steering interface to allow multiple flow steering providers. Use the new interface to implement the current dmfs (device managed flow steering) provider which uses fs_core insertion.

2022-03-11ptp: ocp: add UPF_NO_THRE_TEST flag for serial portsJonathan Lemon1-1/+1
The serial port driver attempts to test for correct THRE behavior on startup. However, it does this by disabling interrupts, and then intentionally trying to trigger an interrupt in order to see if the IIR bit is set in the UART. However, in this FPGA design, the UART interrupt is generated through the MSI vector, so when interrupts are re-enabled after the test, the DMAR-IR reports an unhandled IRTE entry, since no irq handler is installed at this point - it is installed after the test. This only happens on the /second/ open of the UART, since on the first open, the x86_vector has installed and activated by the driver probe, and is correctly handled. When the serial port is closed for the first time, this vector is deactivated and removed, leading to this error.

This enables non-standard MTUs on a per-port basis, with the overall frame size set based on the CPU port. When the MTU is not changed, this should have no effect. Long packets crash the switch with MTUs of greater than 2526, so the maximum is limited for now. Medium packets are sometimes dropped (e.g. TCP over 2477, UDP over 2516-2519, ICMP over 2526), Hence an MTU value of 2400 seems safe.

Dead-lock The patch fixes this issue by following changes: - Bit ICE_FLAG_PLUG_AUX_DEV is kept to be set during ice_plug_aux_dev() call in ice_service_task() - The bit is checked in ice_clear_rdma_cap() and only if it is not set then ice_unplug_aux_dev() is called. If it is set (in other words plugging of aux device was requested and ice_plug_aux_dev() is potentially running) then the function only clears the bit - Once ice_plug_aux_dev() call (in ice_service_task) is finished the bit ICE_FLAG_PLUG_AUX_DEV is cleared but it is also checked whether it was already cleared by ice_clear_rdma_cap(). If so then aux device is unplugged.

Ideally if there isn't a wol_irq, or there is something else that keeps the device from being able to wakeup it should display: "Supports Wake-on: d" This patch checks whether the device can wakup, before using the hard-coded supported flags. This corrects the ethtool reporting, as well as the WOL configuration because ethtool verifies that the mode is supported before attempting it.

However, the current firmware (version 2) doesn't set the GS_CAN_FEATURE_REQ_USB_QUIRK_LPC546XX bit. This patch sets the feature GS_CAN_FEATURE_REQ_USB_QUIRK_LPC546XX to workaround this issue. 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).

2022-03-10can: gs_usb: add usb quirk for NXP LPC546xx controllersPeter Fink1-2/+27
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 Fink1-16/+108
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.
