Expose port function commands to enable / disable RoCE, this is used to control the port RoCE device capabilities. When RoCE is disabled for a function of the port, function cannot create any RoCE specific resources (e.g GID table). It also saves system memory utilization. For example disabling RoCE enable a VF/SF saves 1 Mbytes of system memory per function. Example of a PCI VF port which supports function configuration: Set RoCE of the VF's port function. $ devlink port show pci/0000:06:00.0/2 pci/0000:06:00.0/2: type eth netdev enp6s0pf0vf1 flavour pcivf pfnum 0 vfnum 1 function: hw_addr 00:00:00:00:00:00 roce enable $ devlink port function set pci/0000:06:00.0/2 roce disable $ devlink port show pci/0000:06:00.0/2 pci/0000:06:00.0/2: type eth netdev enp6s0pf0vf1 flavour pcivf pfnum 0 vfnum 1 function: hw_addr 00:00:00:00:00:00 roce disable Signed-off-by:Jiri Pirko <jiri@nvidia.com> Signed-off-by:

Ido Schimmel says: ==================== bridge: mcast: Preparations for EVPN extensions This patchset was split from [1] and includes non-functional changes aimed at making it easier to add additional netlink attributes later on. Future extensions are available here [2]. The idea behind these patches is to create an MDB configuration structure into which netlink messages are parsed into. The structure is then passed in the entry creation / deletion call chain instead of passing the netlink attributes themselves. The same pattern is used by other rtnetlink objects such as routes and nexthops. I initially tried to extend the current code, but it proved to be too difficult, which is why I decided to refactor it to the extensible and familiar pattern used by other rtnetlink objects. Tested using existing selftests and using a new selftest that will be submitted together with the planned extensions.

The checks only require information parsed from the RTM_NEWMDB netlink message and do not rely on any state stored in the bridge driver. Therefore, there is no need to perform the checks in the critical section under the multicast lock. Move the checks out of the critical section. Signed-off-by:

The parsing of the netlink messages and the validity checks are now performed in br_mdb_config_init() so we can remove br_mdb_parse(). This finally allows us to stop passing netlink attributes deep in the MDB control path and only use the MDB configuration structure. Signed-off-by:

The MDB group key (i.e., {source, destination, protocol, VID}) is currently determined under the multicast lock from the netlink attributes. Instead, use the group key from the MDB configuration structure that was prepared before acquiring the lock. No functional changes intended. Signed-off-by: -

The MDB configuration structure (i.e., struct br_mdb_config) now includes all the necessary information from the parsed RTM_{NEW,DEL}MDB netlink messages, so use it. This will later allow us to delete the calls to br_mdb_parse() from br_mdb_add() and br_mdb_del(). No functional changes intended. Signed-off-by: -

Ido Schimmel authored
Netlink attributes are currently passed deep in the MDB creation call chain, making it difficult to add new attributes. In addition, some validity checks are performed under the multicast lock although they can be performed before it is ever acquired. As a first step towards solving these issues, parse the RTM_{NEW,DEL}MDB messages into a configuration structure, relieving other functions from the need to handle raw netlink attributes. Subsequent patches will convert the MDB code to use this configuration structure. This is consistent with how other rtnetlink objects are handled, such as routes and nexthops. Signed-off-by: -

For this, we now allow the creation of dedicated coordinator interfaces to allow a PAN coordinator to serve in the network and set the needed address filters with the hardware. On top of this we have the first part to allow scanning for available 15.4 networks. A new netlink scan group, within the existing nl802154 API, was added. In addition Miquel fixed two issues that have been introduced in the former patches to free an skb correctly and clarifying an expression in the stack.

Hariprasad Kelam says: ==================== CN10KB MAC block support OcteonTx2's next gen platform the CN10KB has RPM_USX MAC which has a different serdes when compared to RPM MAC. Though the underlying HW is different, the CSR interface has been designed largely inline with RPM MAC, with few exceptions though. So we are using the same CGX driver for RPM_USX MAC as well and will have a different set of APIs for RPM_USX where ever necessary. The RPM and RPM_USX blocks support a different number of LMACS. RPM_USX support 8 LMACS per MAC block whereas legacy RPM supports only 4 LMACS per MAC. with this RPM_USX support double the number of DMAC filters and fifo size. This patchset adds initial support for CN10KB's RPM_USX MAC i.e registering the driver and defining MAC operations (mac_ops). With these changes PF and VF netdev packet path will work and PF and VF netdev drivers are able to configure MAC features like pause frames,PFC and loopback etc. Also implements FEC stats for CN10K Mac block RPM and CN10KB Mac block RPM_USX and extends ethtool support for PF and VF drivers by defining get_fec_stats API to display FEC stats. ==================== Link: https://lore.kernel.org/r/20221205070521.21860-1-hkelam@marvell.comSigned-off-by:

CN10K silicon MAC block RPM and CN10KB silicon MAC block RPM_USX both support BASER and RSFEC modes. Also MAC (CGX) on OcteonTx2 silicon variants and MAC (RPM) on OcteonTx3 CN10K are different and FEC stats need to be read differently. CN10KB MAC block (RPM_USX) fec csr offsets are same as CN10K MAC block (RPM) mac_ops points to same fn(). Upper layer interface between RVU AF and PF netdev is kept same. Based on silicon variant appropriate fn() pointer is called to read FEC stats Signed-off-by:

Adds the logic to configure internal loopback and pause frames and assign FIFO length to LMACS. Kernel reads lmac features like lmac type, autoneg, etc from shared firmware data this structure only supports 4 lmacs per MAC, this patch extends this structure to accommodate 8 lmacs.

Rakesh Babu Saladi authored
Most of the code in CGX/RPM driver assumes that max lmacs per given MAC as always, 4 and the number of MAC blocks also as 4. With this assumption, the max number of interfaces supported is hardcoded to 16. This creates a problem as next gen CN10KB silicon MAC supports 8 lmacs per MAC block. This patch solves the problem by using "max lmac per MAC block" value from constant csrs and uses cgx_cnt_max value which is populated based number of MAC blocks supported by silicon. Signed-off-by:

Oleksij Rempel authored
Make MTU configurable on KSZ87xx and KSZ88xx series of switches. Before this patch, pre-configured behavior was different on different switch series, due to opposite meaning of the same bit: - KSZ87xx: Reg 4, Bit 1 - if 1, max frame size is 1532; if 0 - 1514 - KSZ88xx: Reg 4, Bit 1 - if 1, max frame size is 1514; if 0 - 1532 Since the code was telling "... SW_LEGAL_PACKET_DISABLE, true)", I assume, the idea was to set max frame size to 1532. With this patch, by setting MTU size 1500, both switch series will be configured to the 1532 frame limit.

We currently have some complicated code in sfp_probe() which gets the I2C bus depending on whether the sfp node is DT or ACPI, and we use completely separate lookup functions. This could do with being in a separate function to make the code more readable, so move it to a new function, sfp_i2c_get(). We can also use fwnode_find_reference() to lookup the I2C bus fwnode before then decending into fwnode-type specific parsing. A future cleanup would be to move the fwnode-type specific parsing into the i2c layer, which is where it really should be. Signed-off-by:

Horatiu Vultur says: ==================== net: lan966x: Enable PTP on bridge interfaces Before it was not allowed to run ptp on ports that are part of a bridge because in case of transparent clock the HW will still forward the frames so there would be duplicate frames. Now that there is VCAP support, it is possible to add entries in the VCAP to trap frames to the CPU and the CPU will forward these frames. The first part of the patch series, extends the VCAP support to be able to modify and get the rule, while the last patch uses the VCAP to trap the ptp frames. ==================== Link: https://lore.kernel.org/r/20221203104348.1749811-1-horatiu.vultur@microchip.comSigned-off-by:

Currently lan966x, doesn't allow to run PTP over interfaces that are part of the bridge. The reason is when the lan966x was receiving a PTP frame (regardless if L2/IPv4/IPv6) the HW it would flood this frame. Now that it is possible to add VCAP rules to the HW, such to trap these frames to the CPU, it is possible to run PTP also over interfaces that are part of the bridge. Signed-off-by:
