lio_enable_irq (called by napi poll) is reporting to Octeon an inaccurate count of processed rx packets causing Octeon to eventually stop forwarding packets to the host. Fix it by using this formula for an accurate count: processed rx packets = droq->pkt_count - droq->pkts_pending Also increase SOFT_COMMAND_BUFFER_SIZE to match what the firmware expects.

There's a rare pci_driver.probe failure of the VF driver that's caused by PF/VF handshake going out of sync. The culprit is octeon_mbox_write() who ignores an ack timeout condition; it just keeps unconditionally writing all elements of mbox_cmd->data[] even when the other side is not ready for them. Fix it by making each write of mbox_cmd->data[i] conditional to having previously received an ack. Also fix the octeon_mbox_state enum such that each state gets a unique value. Also add ULL suffix to numeric literals in macro definitions. Signed-off-by:

Florian Fainelli says: ==================== net: phy: Create sysfs reciprocal links for attached_dev/phydev This patch series addresses a device topology shortcoming where a program scanning /sys would not be able to establish a mapping between the network device and the PHY device. In the process it turned out that no PHY device documentation existed for sysfs attributes.

Now that we link the network device to its PHY device, document this sysfs symbolic link. Signed-off-by:
-
Florian Fainelli authored
There is currently no way for a program scanning /sys to know whether a network device is attached to a particular PHY device, just like the PHY device is not pointed back to its attached network device. Create a symbolic link in the network device's namespace named "phydev" which points to the PHY device and create a symbolic link in the PHY device's namespace named "attached_dev" that points back to the network device. These links are set up during phy_attach_direct() and removed during phy_detach() for symetry. Signed-off-by:

Convert inet_rtm_getroute to use ip_route_input_rcu and ip_route_output_key_hash_rcu passing the fib_result arg to both. The rcu lock is held through the creation of the response, so the rtable/dst does not need to be attached to the skb and is passed to rt_fill_info directly. In converting from ip_route_output_key to ip_route_output_key_hash_rcu the xfrm_lookup_route in ip_route_output_flow is dropped since flowi4_proto is not set for a route get request. Signed-off-by:

Refactor __ip_route_output_key_hash, pushing the logic between rcu_read_lock ... rcu_read_unlock into a new helper with the fib_result as an input arg.

Jakub Kicinski says: ==================== nfp: devlink port implementation This series adds basic devlink support. The operations we can perform are port show and port split/unsplit. v2: Register devlink first, and then register all the ports. Port {,un}split searches the port list, which is protected by a mutex. If port split is requested before ports are registered we will simply not find the port and return -EINVAL. ==================== Signed-off-by: -

Add initial devlink support. This patch simply switches allocation of per-adapter structure to devlink's priv and register devlink with empty ops table. See following patches for implementation of particular ops. We should now clear the app pointer on exit, this is how devlink callbacks will know app is not initialized. Signed-off-by:

Move mutex init to main file close to structure allocation. This will allow mutex to be taken before net code runs (e.g. from devlink callbacks). While at it remember to destroy the mutex. Signed-off-by:

Jiri Pirko says: ==================== mlxsw: Support firmware flash Add support for device firmware flash on mlxsw spectrum. The firmware files are expected to be in the Mellanox Firmware Archive version 2 (MFA2) format. The firmware flash is triggered on driver initialization time if the device firmware version does not meet the minimum firmware version supported by the driver. Currently, to activate the newly flashed firmware, the user needs to reboot his system. The first patch introduces the mlxfw module, which implements common logic needed for the firmware flash process on Mellanox products, such as the MFA2 format parsing and the firmware flash state machine logic. As the module implements common logic which will be needed by various different Mellanox drivers, it defines a set of callbacks needed to interact with the specific device. Patches 1-5 implement the needed mlxfw callbacks in the mlxsw spectrum driver. Patches 6 and 7 add boot-time firmware upgrade on the mlxsw spectrum driver. Patch 8 adds a fix needed for new firmware versions. ==================== Signed-off-by: -

In new firmware versions, when configuring a {Port, VID} as a router interface, the driver is responsible for enabling the STP filter and disabling learning. Otherwise, packets are discarded.

Make the spectrum module check the current device firmware version, and if it is below the supported version, use the libfirmware API to request a firmware file with the supported firmware version and flash it to the device using the mlxfw module. The firmware file names are expected to be of Mellanox Firmware Archive version 2 (MFA2) format and their name are expected to be in the following pattern: "mlxsw_spectrum-<major>.<minor>.<sub-minor>.mfa2".

The mlxfw module defines several needed callbacks in order to flash the device's firmware. As the mlxfw module is shared between several different drivers, those callbacks are the glue functionality that is responsible for hardware interaction.

The mlxfw module is in charge of common logic needed to flash Mellanox devices firmware, which consists of: - Parse the Mellanox Firmware Archive version 2 (MFA2) format, which is the format used to store the Mellanox firmware. The MFA2 format file can hold firmware for many different silicon variants, differentiated by a unique ID called PSID. In addition, the MFA2 file data section is compressed using xz compression to save both file-system space and memory at extraction time. - Implement the firmware flash state machine logic, which is a common logic for Mellanox products needed to flash the firmware to the device. As the module is shared between different Mellanox products, it defines a set of callbacks to be implemented by the specific driver for hardware interaction. Signed-off-by:

On certain platforms BE3 chips may indicate spurious UEs (unrecoverable error). Because of the UE detection logic was disabled in the driver for BE3 chips. Because of this, even in cases of a real UE, a failover will not occur. This patch re-enables UE detection on BE3 and if a UE is detected, reads the POST register. If the POST register, reports either a FAT_LOG_STATE or a ARMFW_UE, then it means that a valid UE occurred in the chip. Signed-off-by:

Support network namespacing in AF_RXRPC with the following changes: (1) All the local endpoint, peer and call lists, locks, counters, etc. are moved into the per-namespace record. (2) All the connection tracking is moved into the per-namespace record with the exception of the client connection ID tree, which is kept global so that connection IDs are kept unique per-machine. (3) Each namespace gets its own epoch. This allows each network namespace to pretend to be a separate client machine. (4) The /proc/net/rxrpc_xxx files are now called /proc/net/rxrpc/xxx and the contents reflect the namespace. fs/afs/ should be okay with this patch as it explicitly requires the current net namespace to be init_net to permit a mount to proceed at the moment. It will, however, need updating so that cells, IP addresses and DNS records are per-namespace also. Signed-off-by:David Howells <dhowells@redhat.com> Signed-off-by:
