2020-07-23ice: add link lenient and default override supportPaul Greenwalt
Adds functions to check for link override firmware support and get the override settings for a port. The previously supported/default link mode was strict mode. In strict mode link is configured based on get PHY capabilities PHY types with media. Lenient mode is now the default link mode. In lenient mode the link is configured based on get PHY capabilities PHY types without media. This allows the user to configure link that the media does not report. Limit the minimum supported link mode to 25G for devices that support 100G, and 1G for devices that support less than 100G. Default override is only supported in lenient mode. If default override is supported and enabled, then default override values are used for configuring speed and FEC. Default override provide persistent link settings in the NVM.

2020-07-23ice: split ice_discover_caps into two functionsJacob Keller
Using the new ice_aq_list_caps and ice_parse_(dev|func)_caps functions, replace ice_discover_caps with two functions that each take a pointer to the dev_caps and func_caps structures respectively. This makes the side effect of updating the hw->dev_caps and hw->func_caps obvious from reading the implementation of the function. Additionally, it opens the way for enabling reading of device capabilities outside of the initialization flow. By passing in a pointer, another caller will be able to read the capabilities without modifying the HW capabilities structures. As there are no other callers, it is safe to now remove ice_aq_discover_caps and ice_parse_caps.

2020-07-23ice: split ice_parse_caps into separate functionsJacob Keller
The ice_parse_caps function is used to convert the capability block data coming from firmware into a structured format used by other parts of the code. The current implementation directly updates the hw->func_caps and hw->dev_caps structures. It is directly called from within ice_aq_discover_caps. This causes the discover_caps function to have the side effect of modifying the HW capability structures, which is not intuitive. Split this function into ice_parse_dev_caps and ice_parse_func_caps. These functions will take a pointer to the dev_caps and func_caps respectively. Also create an ice_parse_common_caps for sharing the capability logic that is common to device and function. Doing so enables a future refactor to allow reading and parsing capabilities into a local caps structure instead of modifying the members of the HW structure directly.

2020-07-23ice: refactor ice_discover_caps to avoid need to retryJacob Keller
The ice_discover_caps function is used to read the device and function capabilities, updating the hardware capabilities structures with relevant data. The exact number of capabilities returned by the hardware is unknown ahead of time. The AdminQ command will report the total number of capabilities in the return buffer. The current implementation involves requesting capabilities once, reading this returned size, and then re-requested with that size. This isn't really necessary. The firmware interface has a maximum size of ICE_AQ_MAX_BUF_LEN. Firmware can never return more than ICE_AQ_MAX_BUF_LEN / sizeof(struct ice_aqc_list_caps_elem) capabilities. Avoid the retry loop by simply allocating a buffer of size ICE_AQ_MAX_BUF_LEN. This is significantly simpler than retrying. The extra allocation isn't a big deal, as it will be released after we finish parsing the capabilities.

2020-07-23cxgb4: add loopback ethtool self-testVishal Kulkarni
In this test, loopback pkt is created and sent on default queue. The packet goes until the Multi Port Switch (MPS) just before the MAC and based on the specified channel number, it either goes outside the wire on one of the physical ports or looped back to Rx path by MPS. In this case, we're specifying loopback channel, instead of physical ports, so the packet gets looped back to Rx path, instead of getting transmitted on the wire. v3: - Modify commit message to include test details. v2: - Add only loopback self-test.

2020-07-23sfc: convert to new udp_tunnel infrastructureJakub Kicinski
Check MC_CMD_DRV_ATTACH_EXT_OUT_FLAG_TRUSTED, before setting the info, which will hopefully protect us from -EPERM errors the previous code was gracefully ignoring. Ed reports this is not the 100% correct bit, but it's the best approximation we have. Shared code reports the port information back to user space, so we really want to know what was added and what failed. Ignoring -EPERM is not an option. The driver does not call udp_tunnel_get_rx_info(), so its own management of table state is not really all that problematic, we can leave it be. This allows the driver to continue with its copious table syncing, and matching the ports to TX frames, which it will reportedly do one day. Leave the feature checking in the callbacks, as the device may remove the capabilities on reset. Inline the loop from __efx_ef10_udp_tnl_lookup_port() into efx_ef10_udp_tnl_has_port(), since it's the only caller now. With new infra this driver gains port replace - when space frees up in a full table a new port will be selected for offload. Plus efx will no longer sleep in an atomic context. v2: - amend the commit message about TRUSTED not being 100% - add TUNNEL_ENCAP_UDP_PORT_ENTRY_INVALID to mark unsed entries Signed-off-by: Jakub Kicinski <kuba@kernel.org> Acked-By: Edward Cree <ecree@solarflare.com> Signed-off-by: David S.

2020-07-22hv_netvsc: add support for vlans in AF_PACKET modeSriram Krishnan
Vlan tagged packets are getting dropped when used with DPDK that uses the AF_PACKET interface on a hyperV guest. The packet layer uses the tpacket interface to communicate the vlans information to the upper layers. On Rx path, these drivers can read the vlan info from the tpacket header but on the Tx path, this information is still within the packet frame and requires the paravirtual drivers to push this back into the NDIS header which is then used by the host OS to form the packet. This transition from the packet frame to NDIS header is currently missing hence causing the host OS to drop the all vlan tagged packets sent by the drivers that use AF_PACKET (ETH_P_ALL) such as DPDK. Here is an overview of the changes in the vlan header in the packet path: The RX path (userspace handles everything): 1. RX VLAN packet is stripped by HOST OS and placed in NDIS header 2. Guest Kernel RX hv_netvsc packets and moves VLAN info from NDIS header into kernel SKB 3. Kernel shares packets with user space application with PACKET_MMAP. The SKB VLAN info is copied to tpacket layer and indication set TP_STATUS_VLAN_VALID. 4. The user space application will re-insert the VLAN info into the frame The TX path: 1. The user space application has the VLAN info in the frame. 2. Guest kernel gets packets from the application with PACKET_MMAP. 3. The kernel later sends the frame to the hv_netvsc driver. The only way to send VLANs is when the SKB is setup & the VLAN is stripped from the frame. 4. TX VLAN is re-inserted by HOST OS based on the NDIS header. If it sees a VLAN in the frame the packet is dropped.

2020-07-22enetc: Remove the mdio bus on PF probe bailoutClaudiu Manoil
For ENETC ports that register an external MDIO bus, the bus doesn't get removed on the error bailout path of enetc_pf_probe(). This issue became much more visible after recent: commit 07095c025ac2 ("net: enetc: Use DT protocol information to set up the ports") Before this commit, one could make probing fail on the error path only by having register_netdev() fail, which is unlikely. But after this commit, because it moved the enetc_of_phy_get() call up in the probing sequence, now we can trigger an mdiobus_free() bug just by forcing enetc_alloc_msix() to return error, i.e. with the 'pci=nomsi' kernel bootarg (since ENETC relies on MSI support to work), as the calltrace below shows: kernel BUG at /home/eiz/work/enetc/net/drivers/net/phy/mdio_bus.c:648!

Due to devs_in_pkg being zero, the rest of get_phy_c45_ids() is short-circuited too: the following loop never reaches below this point either (it executes "continue" for every device in package, failing to retrieve PHY ID for any of them): /* Now probe Device Identifiers for each device present. */ for (i = 1; i < num_ids; i++) { if (!(devs_in_pkg & (1 << i))) continue; So c45_ids->device_ids remains populated with zeroes. This causes an Aquantia AQR412 PHY (same as any C45 PHY would, in fact) to be probed by the Generic PHY driver. The issue seems to be a case of submitting partially committed work (and therefore testing something other than was submitted). The intention of the patch was to delay exiting the loop until one more condition is reached (the devs_in_pkg read from hardware is either 0, OR mostly f's). So fix the patch to reflect that. Tested with traffic on a LS1028A-QDS, the PHY is now probed correctly using the Aquantia driver. The devs_in_pkg bit field is set to 0xe000009a, and the MMDs that are present have the following IDs: [ 5.600772] libphy: get_phy_c45_ids: device_ids[1]=0x3a1b662 [ 5.618781] libphy: get_phy_c45_ids: device_ids[3]=0x3a1b662 [ 5.630797] libphy: get_phy_c45_ids: device_ids[4]=0x3a1b662 [ 5.654535] libphy: get_phy_c45_ids: device_ids[7]=0x3a1b662 [ 5.791723] libphy: get_phy_c45_ids: device_ids[29]=0x3a1b662 [ 5.804050] libphy: get_phy_c45_ids: device_ids[30]=0x3a1b662 [ 5.816375] libphy: get_phy_c45_ids: device_ids[31]=0x0 [ 7.690237] mscc_felix 0000:00:00.5: PHY [0.5:00] driver [Aquantia AQR412] (irq=POLL) [ 7.704739] mscc_felix 0000:00:00.5: PHY [0.5:01] driver [Aquantia AQR412] (irq=POLL) [ 7.718918] mscc_felix 0000:00:00.5: PHY [0.5:02] driver [Aquantia AQR412] (irq=POLL) [ 7.733044] mscc_felix 0000:00:00.5: PHY [0.5:03] driver [Aquantia AQR412] (irq=POLL) Fixes: bba238ed037c ("net: phy: continue searching for C45 MMDs even if first returned ffff:ffff") Reported-by: Colin King <colin.king@canonical.com> Reported-by: Ioana Ciornei <ioana.ciornei@nxp.com> Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.

2020-07-22net: mscc: ocelot: fix non-initialized CPU port on VSC7514Vladimir Oltean
The VSC7514 is marketed as a 10-port switch, however it has 11 physical ports (0->10) in the block diagram: https://www.microsemi.com/product-directory/ethernet-switches/3992-vsc7514 (also in the device tree at arch/mips/boot/dts/mscc/ocelot.dtsi) Additionally, by architecture it has one more entry in the analyzer block, situated right after the physical ports, for the CPU port module. This is not a physical port, it only represents a channel for frame injection and extraction. That entry for the CPU port is at index 11 in the analyzer. When the register groups for QSYS_SWITCH_PORT_MODE, SYS_PORT_MODE and SYS_PAUSE_CFG are declared to be replicated 11 times, the 11th entry in the array of regfields is not initialized, so the CPU port module is not initialized either. The documentation of QSYS_SWITCH_PORT_MODE for VSC7514 also says that this register group is replicated 12 times, so this patch is simply reflecting that and not introducing any further inconsistency.

2020-07-21ionic: set netdev default nameShannon Nelson
If the host system's udev fails to set a new name for the network port, there is no NETDEV_CHANGENAME event to trigger the driver to send the name down to the firmware. It is safe to set the lif name multiple times, so we add a call early on to set the default netdev name to be sure the FW has something to use in its internal debug logging. Then when udev gets around to changing it we can update it to the actual name the system will be using. Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S.

2020-07-21bareudp: Reverted support to enable & disable rx metadata collectionMartin Varghese
The commit fe80536acf83 ("bareudp: Added attribute to enable & disable rx metadata collection") breaks the the original(5.7) default behavior of bareudp module to collect RX metadadata at the receive. It was added to avoid the crash at the kernel neighbour subsytem when packet with metadata from bareudp is processed. But it is no more needed as the commit 394de110a733 ("net: Added pointer check for dst->ops->neigh_lookup in dst_neigh_lookup_skb") solves this crash.
