There are change in firmware which requires that receiver will disable event interrupts before handling them and enable them after finish with handling. Events still may come into the queue but without receiver interruption. Signed-off-by:

Previously, there is hardware limitation for VF to modify the VLAN filter state, and the VLAN filter state is default enabled. Now the limitation has been removed in some device, so add capability flag to check whether the device supports modify VLAN filter state. If flag on, user will be able to modify the VLAN filter state by ethtool -K. VF needs to send mailbox to request the PF to modify the VLAN filter state for it. Signed-off-by:

There are some features of VF depend on PF, so it's necessary for VF to know whether PF supports. For compatibility, modify the mailbox HCLGE_MBX_GET_TCINFO, extend its function, use to get the basic information of PF, including mailbox api version and PF capabilities. Signed-off-by:

Previously, with hardware limitation, the port VLAN filter are effective for both PF and its VFs simultaneously, so a single function is not able to enable/disable separately, and the VLAN filter state is default enabled. Now some device supports each function to bypass port VLAN filter, then each function can switch VLAN filter separately. Add capability flag to check whether the device supports modify VLAN filter state. If flag on, user will be able to modify the VLAN filter state by ethtool -K. Furtherly, the default VLAN filter state is also changed according to whether non-zero VLAN used. Then the device can receive packet with any VLAN tag if only VLAN 0 used. The function hclge_need_enable_vport_vlan_filter() is used to help implement above changes. And the VLAN filter handle for promisc mode can also be simplified by this function. Signed-off-by:

The struct hclge_vf_vlan_cfg is firstly designed for setting VLAN filter tag. And it's reused for enable RX VLAN offload later. It's strange to use member "is_kill" to indicate "enable". So redefine the struct hclge_vf_vlan_cfg to adapt it. For there are already 3 subcodes being used in function hclge_set_vf_vlan_cfg(), use "switch-case" style for each branch, rather than "if-else". Also simplify the assignment for each branch to make it more clearly. Signed-off-by:

Vladimir Oltean says: ==================== Part 2 of SJA1105 DSA driver preparation for new switch introduction (SJA1110) This series is a continuation of: https://patchwork.kernel.org/project/netdevbpf/cover/20210524131421.1030789-1-olteanv@gmail.com/ even though it isn't the first time these patches are submitted (they were part of the group previously called "Add NXP SJA1110 support to the sja1105 DSA driver"): https://patchwork.kernel.org/project/netdevbpf/cover/20210526135535.2515123-1-vladimir.oltean@nxp.com/ but I broke that up again since these patches are already reviewed, for the most part. There are no changes compared to v2 and v1. This series of patches contains: - an adaptation of the driver to the new "ethernet-ports" OF node name - an adaptation of the driver to support more than 1 SGMII port - a generalization of the supported phy_interface_t values per port - an adaptation to encode SPEED_10, SPEED_100, SPEED_1000 into the hardware registers differently depending on switch revision - a consolidation of the PHY interface type used for RGMII and another one for the API exposed for sja1105_dynamic_config_read() ==================== Link: https://lore.kernel.org/r/20210530225939.772553-1-olteanv@gmail.comSigned-off-by:

The SJA1105 has a static configuration comprised of a number of tables with entries. Some of these can be read and modified at runtime as well, through the dynamic configuration interface. As a careful reader can notice from the comments in this file, the software interface for accessing a table entry through the dynamic reconfiguration is a bit of a no man's land, and varies wildly across switch generations and even from one kind of table to another. I have tried my best to come up with a software representation of a 'common denominator' SPI command to access a table entry through the dynamic configuration interface: struct sja1105_dyn_cmd { bool search; u64 valid; /* must be set to 1 */ u64 rdwrset; /* 0 to read, 1 to write */ u64 errors; u64 valident; /* 0 if entry is invalid, 1 if valid */ u64 index; }; Relevant to this patch is the VALIDENT bit, which for READ commands is populated by the switch and lets us know if we're looking at junk or at a real table entry. In SJA1105, the dynamic reconfiguration interface for management routes has notably not implemented the VALIDENT bit, leading to a workaround to ignore this field in sja1105_dynamic_config_read(), as it will be set to zero, but the data is valid nonetheless. In SJA1110, this pattern has sadly been abused to death, and while there are many more tables which can be read back over the dynamic config interface compared to SJA1105, their handling isn't in any way more uniform. Generally speaking, if there is a single possible entry in a given table, and loading that table in the static config is mandatory as per the documentation, then the VALIDENT bit is deemed as redundant and more than likely not implemented. So it is time to make the workaround more official, and add a bit to the flags implemented by dynamic config tables. It will be used by more tables when SJA1110 support arrives.

In SJA1105, the xMII Mode Parameters Table field called PHY_MAC denotes the 'role' of the port, be it a PHY or a MAC. This makes a difference in the MII and RMII protocols, but RGMII is symmetric, so either PHY or MAC settings result in the same hardware behavior. The SJA1110 is different, and the RGMII ports only work when configured in MAC mode, so keep the port roles in MAC mode unconditionally. Why we had an RGMII port in the PHY role in the first place was because we wanted to have a way in the driver to denote whether RGMII delays should be applied based on the phy-mode property or not. This is already done in sja1105_parse_rgmii_delays() based on an intermediary struct sja1105_dt_port (which contains the port role). So it is a logical fallacy to use the hardware configuration as a scratchpad for driver data, it isn't necessary. We can also remove the gating condition for applying RGMII delays only for ports in the PHY role. The .setup_rgmii_delay() method looks at the priv->rgmii_rx_delay[port] and priv->rgmii_tx_delay[port] properties which are already populated properly (in the case of a port in the MAC role they are false). Removing this condition generates a few more SPI writes for these ports (clearing the RGMII delays) which are perhaps useless for SJA1105P/Q/R/S, where we know that the delays are disabled by default. But for SJA1110, the firmware on the embedded microcontroller might have done something funny, so it's always a good idea to clear the RGMII delays if that's what Linux expects. Signed-off-by:

In order to support the new speed of 2500Mbps, the SJA1110 has achieved the great performance of changing the encoding in the MAC Configuration Table for the port speeds of 10, 100, 1000 compared to SJA1105. Because this is a common driver, we need a layer of indirection in order to program the hardware with the right values irrespective of switch generation. Signed-off-by:

On the SJA1105, all ports support the parallel "xMII" protocols (MII, RMII, RGMII) except for port 4 on SJA1105R/S which supports only SGMII. This was relatively easy to model, by special-casing the SGMII port. On the SJA1110, certain ports can be pinmuxed between SGMII and xMII, or between SGMII and an internal 100base-TX PHY. This creates problems, because the driver's assumption so far was that if a port supports SGMII, it uses SGMII. We allow the device tree to tell us how the port pinmuxing is done, and check that against a PHY interface type compatibility matrix for plausibility. The other big change is that instead of doing SGMII configuration based on what the port supports, we do it based on what is the configured phy_mode of the port. The 2500base-x support added in this patch is not complete. Signed-off-by:

So far we've succeeded in operating without keeping a copy of the phy-mode in the driver, since we already have the static config and we can look at the xMII Mode Parameters Table which already holds that information. But with the SJA1110, we cannot make the distinction between sgmii and 2500base-x, because to the hardware's static config, it's all SGMII. So add a phy_mode property per port inside struct sja1105_private. Signed-off-by:

Looking at the SGMII PCS from SJA1110, which is accessed indirectly through a different base address as can be seen in the next patch, it appears odd that the address accessed through indirection still references the base address from the SJA1105S register map (first MDIO register is at 0x1f0000), when it could index the SGMII registers starting from zero. Except that the 0x1f0000 is not a base address at all, it seems. It is 0x1f << 16 | 0x0000, and 0x1f is coding for the vendor-specific MMD2. So, it turns out, the Synopsys PCS implements all its registers inside the vendor-specific MMDs 1 and 2 (0x1e and 0x1f). This explains why the PCS has no overlaps (for the other MMDs) with other register regions of the switch (because no other MMDs are implemented). Change the code to remove the SGMII "base address" and explicitly encode the MMD for reads/writes. This will become necessary for SJA1110 support.

The SJA1105 R and S switches have 1 SGMII port (port 4). Because there is only one such port, there is no "port" parameter in the configuration code for the SGMII PCS. However, the SJA1110 can have up to 4 SGMII ports, each with its own SGMII register map. So we need to generalize the logic. Signed-off-by:

Since commit f2f3e09396be ("net: dsa: sja1105: be compatible with "ethernet-ports" OF node name"), DSA supports the "ethernet-ports" name for the container node of the ports, but the sja1105 driver doesn't, because it handles some device tree parsing of its own. Add the second node name as a fallback. Signed-off-by: -

This is a complement to commit aa6dd211 ("inet: use bigger hash table for IP ID generation"), but focusing on some specific aspects of IPv6. Contary to IPv4, IPv6 only uses packet IDs with fragments, and with a minimum MTU of 1280, it's much less easy to force a remote peer to produce many fragments to explore its ID sequence. In addition packet IDs are 32-bit in IPv6, which further complicates their analysis. On the other hand, it is often easier to choose among plenty of possible source addresses and partially work around the bigger hash table the commit above permits, which leaves IPv6 partially exposed to some possibilities of remote analysis at the risk of weakening some protocols like DNS if some IDs can be predicted with a good enough probability. Given the wide range of permitted IDs, the risk of collision is extremely low so there's no need to rely on the positive increment algorithm that is shared with the IPv4 code via ip_idents_reserve(). We have a fast PRNG, so let's simply call prandom_u32() and be done with it. Performance measurements at 10 Gbps couldn't show any difference with the previous code, even when using a single core, because due to the large fragments, we're limited to only ~930 kpps at 10 Gbps and the cost of the random generation is completely offset by other operations and by the network transfer time. In addition, this change removes the need to update a shared entry in the idents table so it may even end up being slightly faster on large scale systems where this matters. The risk of at least one collision here is about 1/80 million among 10 IDs, 1/850k among 100 IDs, and still only 1/8.5k among 1000 IDs, which remains very low compared to IPv4 where all IDs are reused every 4 to 80ms on a 10 Gbps flow depending on packet sizes.
