Boris Sukholitko says: ==================== net/sched: act_vlan: Fix modify to allow 0 Currently vlan modification action checks existence of vlan priority by comparing it to 0. Therefore it is impossible to modify existing vlan tag to have priority 0. For example, the following tc command will change the vlan id but will not affect vlan priority: tc filter add dev eth1 ingress matchall action vlan modify id 300 \ priority 0 pipe mirred egress redirect dev eth2 The incoming packet on eth1: ethertype 802.1Q (0x8100), vlan 200, p 4, ethertype IPv4 will be changed to: ethertype 802.1Q (0x8100), vlan 300, p 4, ethertype IPv4 although the user has intended to have p == 0. The fix is to add tcfv_push_prio_exists flag to struct tcf_vlan_params and rely on it when deciding to set the priority. The same flag is used to avoid dumping unset vlan priority. Change Log: v3 -> v4: - revert tcf_vlan_get_fill_size change: total size calculation may race vs dump v2 -> v3: - Push assumes that the priority is being set - tcf_vlan_get_fill_size accounts for priority existence v1 -> v2: - Do not dump unset priority and fix tests accordingly - Test for priority 0 modification ==================== Reviewed-by:

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:

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:

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. Signed-off-by:

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:
