2019-06-10net: mvpp2: Only clear the stat counters at port initMaxime Chevallier
When first configuring a port on PPv2, we want to clear the internal counters so that we don't get values from previous boot stages. However, we can't really clear these counters when resetting the MAC, since there are valid reasons to do so while the port is being used, such as when reconfiguring the interface mode with the PHY.

2019-05-29net: phylink: Add struct phylink_config to PHYLINK APIIoana Ciornei
The phylink_config structure will encapsulate a pointer to a struct device and the operation type requested for this instance of PHYLINK. This patch does not make any functional changes, it just transitions the PHYLINK internals and all its users to the new API. A pointer to a phylink_config structure will be passed to phylink_create() instead of the net_device directly. Also, the same phylink_config pointer will be passed back to all phylink_mac_ops callbacks instead of the net_device. Using this mechanism, a PHYLINK user can get the original net_device using a structure such as 'to_net_dev(config->dev)' or directly the structure containing the phylink_config using a container_of call. At the moment, only the PHYLINK_NETDEV is defined as a valid operation type for PHYLINK. In this mode, a valid reference to a struct device linked to the original net_device should be passed to PHYLINK through the phylink_config structure. This API changes is mainly driven by the necessity of adding a new operation type in PHYLINK that disconnects the phy_device from the net_device and also works when the net_device is lacking.

2019-05-25net: mvpp2: cls: Use RSS contexts to handle RSS tablesMaxime Chevallier
The PPv2 controller has 8 RSS tables that are shared across all ports on a given PPv2 instance. The previous implementation allocated one table per port, leaving others unused. By using RSS contexts, we can make use of multiple RSS tables per port, one being the default table (always id 0), the other ones being used as destinations for flow steering, in the same way as rx rings. This commit introduces RSS contexts management in the PPv2 driver. We always reserve one table per port, allocated when the port is probed. The global table list is stored in the struct mvpp2, as it's a global resource. Each port then maintains a list of indices in that global table, that way each port can have it's own numbering scheme starting from 0. One limitation that seems unavoidable is that the hashing parameters are shared across all RSS contexts for a given port. Hashing parameters for ctx 0 will be applied to all contexts.

2019-05-01net: mvpp2: cls: Add Classification offload supportMaxime Chevallier
This commit introduces basic classification offloading support for the PPv2 controller. The PPv2 classifier has many classification engines, for now we only use the C2 TCAM match engine. This engine allows to perform ternary lookups on 64 bits keys (called Header Extracted Key), that are built by extracting fields from the packet header and concatenating them. At most 4 fields can be extracted for a single lookup. This basic implementation allows to build the HEK from the following fields : - L4 source and destination ports (for UDP and TCP) More fields are to be added in the future. Classification flows are added through the ethtool interface, using the newly introduced flow_rule infrastructure as an internal rule representation, allowing to more easily implement tc flower rules if need be. The internal design for now allocates one range of 4 rules per port due to the internal design of the flow table, which uses 22 sub-flows. When inserting a classification rule, the rule is created in every relevant sub-flow. This low rule-count is a very simple design which reaches quickly the limitations of the flow table ordering, but guarantees that the rule ordering will always be respected.

This patch modifies the port_disable() helper to always disable both the GMAC and the XLG MAC when called. At boot time we do not know of a port was enabled in the firmware/bootloader, and if so what mode was used (hence which of the two MACs was used).

2019-03-01net: mvpp2: fix the computation of the RXQsAntoine Tenart
The patch fixes the computation of RXQs being used by the PPv2 driver, which is set depending on the PPv2 engine version and the queue mode used. There are three cases: - PPv2.1: 1 RXQ per CPU. - PPV2.2 with MVPP2_QDIST_MULTI_MODE: 1 RXQ per CPU. - PPv2.2 with MVPP2_QDIST_SINGLE_MODE: 1 RXQ is shared between the CPUs. The PPv2 engine supports a maximum of 32 queues per port. This patch adds a check so that we do not overstep this maximum. It appeared the calculation was broken for PPv2.1 engines since f8c6ba8424b0, as PPv2.1 ports ended up with a single RXQ while they needed 4. This patch fixes it.

2019-02-09net: marvell: mvpp2: clear flow control modes in 10G modeRussell King
When mvpp2 configures the flow control modes in mvpp2_xlg_config() for 10G mode, it only ever set the flow control enable bits. There is no mechanism to clear these bits, which means that userspace is unable to use standard APIs to disable flow control (the only way is to poke the register directly.) Fix the missing bit clearance to allow flow control to be disabled. This means that, by default, as there is no negotiation in 10G modes with mvpp2, flow control is now disabled rather than being rx-only.

2019-02-08net: marvell: mvpp2: only reprogram what is necessary on mac_configRussell King
mac_config() can be called at any point, and the expected behaviour from MAC drivers is to only reprogram when necessary - and certainly avoid taking the link down on every call. Unfortunately, mvpp2 does exactly that - it takes the link down, and reprograms everything, and then releases the forced-link down. This is bad, it can cause the link to bounce: - SFP detects signal, disables LOS indication. - SFP code calls into phylink, calling phylink_sfp_link_up() which triggers a resolve. - phylink_resolve() calls phylink_get_mac_state() and finds the MAC reporting link up. - phylink wants to configure the pause mode on the MAC, so calls phylink_mac_config() - mvpp2 takes the link down temporarily, generating a MAC link down event followed by another MAC link event. - phylink calls mac_link_up() and then processes the MAC link down event. - phylink_resolve() gets called again, registers the link down, and calls mach_link_down() before re-running itself. - phylink_resolve() starts again at step 3 above. This sequence repeats. GMAC versions prior to mvpp2 do not require the link to be taken down except when certain link properties (eg, switching between SGMII and 1000base-X mode, or enabling/disabling in-band negotiation) are changed. Implement this for mvpp2. Tested-by: Sven Auhagen <sven.auhagen@voleatech.de> Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-02-08net: marvell: mvpp2: fix stuck in-band SGMII negotiationRussell King
It appears that the mvpp22 can get stuck with SGMII negotiation. The symptoms are that in-band negotiation never completes and the partner (eg, PHY) never reports SGMII link up, or if it supports negotiation bypass, goes into negotiation bypass mode (which will happen when the PHY sees that the MAC is alive but gets no response.) Triggering the PHY end of the link to re-negotiate results in the bypass bit clearing on the PHY, and then re-setting - indicating that the problem is at the mvpp22 GMAC end. Asserting the GMAC reset and de-asserting it resolves the issue. Arrange to assert the GMAC reset at probe time, and deassert it only after we have configured the GMAC for the appropriate mode. This resolves the issue. Tested-by: Sven Auhagen <sven.auhagen@voleatech.de> Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-02-08net: marvell: mvpp2: phylink compliance updatesRussell King
Sven Auhagen reported issues with negotiation on a couple of his platforms using a mixture of SFP and PHYs in various different modes. Debugging to root cause proved difficult, but essentially the problem comes down to the mvpp2 phylink implementation being slightly at odds with what is expected. phylink operates in three modes: phy, fixed-link, and in-band mode. In the first two modes, the expected behaviour from a MAC driver is that phylink resolves the operating mode and passes the mode to the MAC driver for it to program, including when the link should be brought up or taken down. This is basically the same as the libphy approach. This does not negate the requirement to advertise a correct control word for interface modes that have control words where that can be reasonably controlled. The second mode is in-band mode, where the MAC is expected to use the in-band control word to determine the operating mode. The mvneta driver implements the correct pattern required to support this: configure the port interface type separately from the in-band mode(s). This is now specified in the phylink documentation patches. mvpp2 was programming in-band mode for SGMII and the 802.3z modes no what, and avoided forcing the link up in fixed/phy modes. This caused a problem with some boards where the PHY is by default programmed to enter AN bypass mode, the PHY would report that the link was up, but the mvpp2 never completed the exchange of control word. Another issue that mvpp2 has is it sets SGMII AN format control word for both SGMII and 802.3z modes. The format of the control word is defined by MVPP2_GMAC_INBAND_AN_MASK, which should be set for SGMII and clear for 802.3z. Available Marvell documentation for earlier GMAC implementations does not make this clear, but this has been ascertained via extensive testing on earlier GMAC implementations, and then confirmed with a Macchiatobin Single Shot connected to a Clearfog: when MVPP2_GMAC_INBAND_AN_MASK is set, the clearfog does not receive the advertised pause mode settings. Lastly, there is no flow control in the in-band control word in Cisco SGMII, setting the flow control autonegotiation bit even with a PHY that has the Marvell extension to send this information does not result in the flow control being enabled at the MAC. We need to do this manually using the information provided via phylink. Re-code mvpp2's mac_config() and mac_link_up() to follow this pattern. This allows Sven Auhagen's board and Macchiatobin to reliably bring the link up with the 88e1512 PHY with phylink operating in PHY mode with COMPHY built as a module but the rest of the networking built-in, and u-boot having brought up the interface. in-band mode requires an additional patch to resolve another problem.

2019-02-05net: marvell: mvpp2: fix lack of link interruptsRussell King
Sven Auhagen reports that if he changes a SFP+ module for a SFP module on the Macchiatobin Single Shot, the link does not come back up. For Sven, it is as easy as: - Insert a SFP+ module connected, and use ping6 to verify link is up. - Remove SFP+ module - Insert SFP 1000base-X module use ping6 to verify link is up: Link up event did not trigger and the link is down but that doesn't show the problem for me. Locally, this has been reproduced by: - Boot with no modules. - Insert SFP+ module, confirm link is up. - Replace module with 25000base-X module. Confirm link is up. - Set remote end down, link is reported as dropped at both ends. - Set remote end up, link is reported up at remote end, but not local end due to lack of link interrupt. Fix this by setting up both GMAC and XLG interrupts for port 0, but only unmasking the appropriate interrupt according to the current mode set in the mac_config() method. However, only do the mask/unmask dance when we are really changing the link mode to avoid missing any link interrupts.

When acpi_match_device fails, its return value is NULL. Directly using the return value without a check may result in a NULL-pointer dereference.

2018-12-04net: mvpp2: fix detection of 10G SFP modulesBaruch Siach
The mvpp2_phylink_validate() relies on the interface field of phylink_link_state to determine valid link modes. However, when called from phylink_sfp_module_insert() this field in not initialized. The default switch case then excludes 10G link modes. This allows 10G SFP modules that are detected correctly to be configured at max rate of 2.5G. Catch the uninitialized PHY mode case, and allow 10G rates.

2018-10-30net: mvpp2: Fix affinity hint allocationMarc Zyngier
The mvpp2 driver has the curious behaviour of passing a stack variable to irq_set_affinity_hint(), which results in the kernel exploding the first time anyone accesses this information. News flash: userspace does, and irqbalance will happily take the machine down. Great stuff. An easy fix is to track the mask within the queue_vector structure, and to make sure it has the same lifetime as the interrupt itself.

2018-10-05net: mvpp2: Extract the correct ethtype from the skb for tx csum offloadMaxime Chevallier
When offloading the L3 and L4 csum computation on TX, we need to extract the l3_proto from the ethtype, independently of the presence of a vlan tag. The actual driver uses skb->protocol as-is, resulting in packets with the wrong L4 checksum being sent when there's a vlan tag in the packet header and checksum offloading is enabled. This commit makes use of vlan_protocol_get() to get the correct ethtype regardless the presence of a vlan tag.
