Simon Horman says: ==================== ravb: remove use of undocumented registers this short series cleans up the RAVB driver a little. The first patch corrects the spelling of the FBP field of SFO register. This register field is unused and should have no run-time effect. The remaining patches remove the use of undocumented registers after some consultation with the internal Renesas BSP team. Changes in v2: * Corrected mangled state of first patch * Patches 2/4 and 3/4 split out of a large patch * Accumulated acks * Tweaked changelog * Claimed authorship of all patches v1 of this series was tested on the following platforms. No behaviour change is expected in v2. * E3 Ebisu * H3 Salvator-XS (ES2.0) * M3-W Salvator-XS * M3-N Salvator-XS * RZ/G1C iW-RainboW-G23S ==================== Signed-off-by:David S.

Only use the TROCR register on R-Car Gen3 as it is not present on other SoCs. Offsets used for the undocumented registers are considered reserved and should not be written to. After some internal investigation with Renesas it remains unclear why this driver accesses these fields on R-Car Gen2 but regardless of what the historical reasons are the current code is considered incorrect.

This patch removes the use of the undocumented BOC bit of the CCC register. Current documentation for EtherAVB (ravb) describes the offset of what the driver uses as the BOC bit as reserved and that only a value of 0 should be written. After some internal investigation with Renesas it remains unclear why this driver accesses these fields but regardless of what the historical reasons are the current code is considered incorrect.

Since hclge_get_reset_level may return HNAE3_NONE_RESET, so hdev->reset_level can not be assigned with the return value in the hclge_reset(), otherwise, it will cause the use of hdev->reset_level in hclge_reset_event get into error.

In original codes, the VF index used incorrectly in function hclge_set_vlan_rx_offload_cfg() and hclge_set_vlan_rx_offload_cfg(). When VF id is greater than 8, for example 9, it will set the same bit with VF id 1. This patch fixes it by using vport->vport_id % HCLGE_VF_NUM_PER_CMD / HCLGE_VF_NUM_PER_BYTE as the array index, instead of vport->vport_id / HCLGE_VF_NUM_PER_CMD.

While running stmmac selftests I found that in my 1G setup some tests were failling when running with PHY loopback enabled. It looks like when loopback is enabled the PHY will report that Link is down even though there is a valid connection. As in loopback mode the data will not be sent anywhere we can bypass the logic of checking if Link is valid thus saving unecessary reads. Signed-off-by:

For high speed adapter like Mellanox CX-5 card, it can reach upto 100 Gbits per second bandwidth. Currently htb already supports 64bit rate in tc utility. However police action rate and peakrate are still limited to 32bit value (upto 32 Gbits per second). Add 2 new attributes TCA_POLICE_RATE64 and TCA_POLICE_RATE64 in kernel for 64bit support so that tc utility can use them for 64bit rate and peakrate value to break the 32bit limit, and still keep the backward binary compatibility.

Offloaded OvS datapath rules are translated one to one to tc rules, for example the following simplified OvS rule: recirc_id(0),in_port(dev1),eth_type(0x0800),ct_state(-trk) actions:ct(),recirc(2) Will be translated to the following tc rule: $ tc filter add dev dev1 ingress \ prio 1 chain 0 proto ip \ flower tcp ct_state -trk \ action ct pipe \ action goto chain 2 Received packets will first travel though tc, and if they aren't stolen by it, like in the above rule, they will continue to OvS datapath. Since we already did some actions (action ct in this case) which might modify the packets, and updated action stats, we would like to continue the proccessing with the correct recirc_id in OvS (here recirc_id(2)) where we left off. To support this, introduce a new skb extension for tc, which will be used for translating tc chain to ovs recirc_id to handle these miss cases. Last tc chain index will be set by tc goto chain action and read by OvS datapath. Signed-off-by:

The UPS feature only works for runtime suspend, so UPS flags only need to be set before enabling runtime suspend. Therefore, I create a struct to record relative information, and use it before runtime suspend. All chips could record such information, even though not all of them support the feature of UPS. Then, some functions could be combined. Signed-off-by:

Arseny Solokha says: ==================== gianfar: some assorted cleanup This is a cleanup series for the gianfar Ethernet driver, following up a discussion in [1]. It is intended to precede a conversion of gianfar from PHYLIB to PHYLINK API, which will be submitted later in its version 2. However, it won't make a conversion cleaner, except for the last patch in this series. Obviously this series is not intended for -stable. The first patch looks super controversial to me, as it moves lots of code around for the sole purpose of getting rid of static forward declarations in two translation units. On the other hand, this change is purely mechanical and cannot do any harm other than cluttering git blame output. I can prepare an alternative patch for only swapping adjacent functions around, if necessary. The second patch is a trivial follow-up to the first one, making functions that are only called from the same translation unit static. The third patch removes some now unused macro and structure definitions from gianfar.h, slipped away from various cleanups in the past. The fourth patch, also suggested in [1], makes the driver consistently use PHY connection type value obtained from a Device Tree node, instead of ignoring it and using the one auto-detected by MAC, when connecting to PHY. Obviously a value has to be specified correctly in DT source, or omitted altogether, in which case the driver will fall back to auto-detection. When querying a DT node, the driver will also take both applicable properties into account by making a proper API call instead of open-coding the lookup half-way correctly.

Historically, gianfar only used phy-connection-type DT property when connected to PHY in the rgmii-id mode. It ignored the property otherwise, relying on the connection type auto-detection carried out by MAC and providing that reconstructed mode to of_phy_connect(). It also did not consider alternative phy-mode property at all. Make the driver properly query DT node for PHY connection type first and use an obtained value if it was specified there. Otherwise, if a particular DT relies on connection type auto-detection, fall back to reconstructing the value from MAC registers, as before. Signed-off-by:
