Vladimir Oltean says: ==================== FDB updates for SJA1105 DSA driver This patch series adds: - FDB switchdev support for the second generation of switches (P/Q/R/S). I could test/code these now that I got a board with a SJA1105Q. - Management route support for SJA1105 P/Q/R/S. This is needed to send PTP/STP/management frames over the CPU port. - Logic to hide private DSA VLANs from the 'bridge fdb' commands. The new FDB code was also tested and still works on SJA1105T. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

TX VLANs and RX VLANs are an internal implementation detail of DSA for frame tagging. They work by installing special VLANs on switch ports in the operating modes where no behavior change w.r.t. VLANs can be observed by the user. Therefore it makes sense to hide these VLANs in the 'bridge fdb' command, as well as translate the pvid into the RX VID and TX VID on 'bridge fdb add' and 'bridge fdb del' commands. Signed-off-by:

This is a cosmetic patch that simplifies the code by removing a redundant check. A logical AND-with-zero performed on a zero is still zero. Signed-off-by:

This adds support for manipulating the L2 forwarding database (dump, add, delete) for the second generation of NXP SJA1105 switches. At the moment only FDB entries installed statically through 'bridge fdb' are visible in the dump callback - the dynamically learned ones are still under investigation. Signed-off-by:

Management routes are one-shot FDB rules installed on the CPU port for sending link-local traffic. They are a prerequisite for STP, PTP etc to work. Also make a note that removing a management route was not supported on the previous generation of switches. Signed-off-by:

Conceptually, if an entry is not found in the requested hardware table, it is not an invalid request - so change the error returned appropriately. Signed-off-by:

These are needed in order to implement the switchdev FDB callbacks. Compared to the E/T generation, not only the ABI (bit offsets) is different, but also the introduction of the HOSTCMD field which permits O(1) TCAM search for an FDB entry. Make use of the newly introduce OP_SEARCH to permit that. It will be used while adding and deleting an FDB entry (to see whether it exists or not). Signed-off-by:

Vladimir Oltean authored
The DSA callbacks were written with the E/T (first generation) in mind, which is quite different. For P/Q/R/S completely new implementations need to be provided, which are held as function pointers in the priv->info structure. We are taking a slightly roundabout way for this (a function from sja1105_main.c reads a structure defined in sja1105_spi.c that points to a function defined in sja1105_main.c), but it is what it is. The FDB dump callback works for both families, hence no function pointer for that. Signed-off-by:

Vladimir Oltean authored
Only a single dynamic configuration table of the SJA1105 P/Q/R/S supports this operation: the FDB. To keep the existing structure in place (sja1105_dynamic_config_read and sja1105_dynamic_config_write) and not introduce any new function, a convention is made for sja1105_dynamic_config_read that a negative index argument denotes a search for the entry provided as argument.

This appends to the L2 Forwarding and L2 Forwarding Parameters tables (originally added for first-generation switches) the bits that are new in the second generation. Signed-off-by:

Vladimir Oltean authored
This was inadvertently copied from the SJA1105 E/T structure and not tested. Cross-checking with the P/Q/R/S documentation (UM11040) makes it immediately obvious what the correct bit offsets for this field are. Signed-off-by:
-
Vladimir Oltean authored
This structure is merely an implementation detail and should be hidden from the sja1105_dynamic_config.h header, which provides to the rest of the driver an abstract access to the dynamic configuration interface of the switch. Signed-off-by:

Huazhong Tan says: ==================== code optimizations & bugfixes for HNS3 driver This patch-set includes code optimizations and bugfixes for the HNS3 ethernet controller driver. [patch 1/10] removes the redundant core reset type [patch 2/10 - 3/10] fixes two VLAN related issues [patch 4/10] fixes a TM issue [patch 5/10 - 10/10] includes some patches related to RAS & MSI-X error Change log: V1->V2: removes two patches which needs to change HNS's infiniband driver as well, they will be upstreamed later with the infiniband's one. ==================== Signed-off-by: -

All RAS and MSI-X should be enabled just in the final stage of HNS3 initialization. It means that they should be enabled in hclge_init_xxx_client_instance instead of hclge_ae_dev(). Especially MSI-X, if it is enabled before opening vector0 IRQ, there are some chances that a MSI-X error will cause failure on initialization of NIC client instane. So this patch delays enabling of HW errors. Otherwise, we also separate enabling of ROCE RAS from NIC, because it's not reasonable to enable ROCE RAS if we even don't have a ROCE driver.

There are four commands being used to query and clear RAS and MSI-X interrupts status. They should be contained in array of special opcodes because these commands have several descriptors, and we need to judge return value in the first descriptor rather than the last one as other opcodes. In addition, we shouldn't set the NEXT_FLAG of first descriptor. This patch fixes above issues. Signed-off-by:

LINK_UP and LINK_DOWN are two bits of MAC tunnel interrupts, but previous HNS3 driver didn't handle them. If they were enabled, value of these two bits will change during link down and link up, which will cause HNS3 driver keep receiving IRQ but can't handle them. This patch adds handling of these two bits of interrupts, we will record and clear them as what we do to other MAC tunnel interrupts. Signed-off-by:

If we add a VF without loading hclgevf.ko and then there is a RAS error occurs, PCIe AER will call error_detected and slot_reset of all functions, and will get a NULL pointer when we check ad_dev->ops->handle_hw_ras_error. This will cause a call trace and failures on handling of follow-up RAS errors. This patch check ae_dev and ad_dev->ops at first to solve above issues. Signed-off-by:

In orginal codes, the driver only restore VLAN filter entries for PF after reset, the VLAN entries of VF will lose in this case.

VF VLAN table can only support no more than 256 VLANs. When user adds too many VLANs, the VF VLAN table will be full, and firmware will close the VF VLAN table for the function. When VF VLAN table is full, and user keeps adding new VLANs, it's unnecessary to configure the VF VLAN table, because it will always fail, and print warning message. The worst case is adding 4K VLANs, and doing reset, it will take much time to restore these VLANs, which may cause VF reset fail by timeout.

Sean Wang says: ==================== Add MT7629 ethernet support MT7629 inlcudes two sets of SGMIIs used for external switch or PHY, and embedded switch (ESW) via GDM1, GePHY via GMAC2, so add several patches in the series to make the code base common with the old SoCs. The patch 1, 3 and 6, adds extension for SGMII to have the hardware configured for 1G, 2.5G and AN to fit the capability of the target PHY. In patch 6 could be an example showing how to use these configurations for underlying PHY speed to match up the link speed of the target PHY. The patch 4 is used for automatically configured the hardware path from GMACx to the target PHY by the description in deviceetree topology to determine the proper value for the corresponding MUX. The patch 2 and 5 is for the update for MT7629 including dt-binding document and its driver. ==================== Signed-off-by: -
