Currently, multicast packet filtering is accomplished by installing MCAM rule that matches all-multicast MAC address and has its NPC_RX_ACTION set to unicast to PF. Similarly promisc feature is achieved by installing MCAM rule that matches all the traffic received by the channel and unicast the packets to PF. This approach only applies to PF and is not scalable across VFs. This patch adds support for PF/VF multicast and promisc feature by reserving NIX_RX_MCE_S entries from the global MCE list allocated during NIX block initialization. The NIX_RX_MCE_S entries create a linked list with a flag indicating the end of the list, and each entry points to a PF_FUNC (either PF or VF). When a packet NPC_RX_ACTION is set to MCAST, the corresponding NIX_RX_MCE_S list is traversed and the packet is queued to each PF_FUNC available on the list. The PF or VF driver adds the multicast/promisc packet match entry and updates the MCE list with correspondng PF_FUNC. When a PF or VF interface is disabled, the corresponding NIX_RX_MCE_S entry is removed from the MCE list and the MCAM entry will be disabled if the list is empty. Signed-off-by:

The commit d96febed ("net: stmmac: arrange Tx tail pointer update to stmmac_flush_tx_descriptors") introduced the following coverity warning:- 1. Unintentional integer overflow (OVERFLOW_BEFORE_WIDEN) overflow_before_widen: Potentially overflowing expression 'tx_q->cur_tx * desc_size' with type 'unsigned int' (32 bits, unsigned) is evaluated using 32-bit arithmetic, and then used in a context that expects an expression of type dma_addr_t (64 bits, unsigned). Fixed this by assigning tx_tail_addr to dma_addr_t type, as dma_addr_t datatype is decided by CONFIG_ARCH_DMA_ADDR_T_64_BIT.

Ioana Ciornei says: ==================== ACPI support for dpaa2 driver This patch set provides ACPI support to DPAA2 network drivers. It also introduces new fwnode based APIs to support phylink and phy layers Following functions are defined: phylink_fwnode_phy_connect() fwnode_mdiobus_register_phy() fwnode_get_phy_id() fwnode_phy_find_device() device_phy_find_device() fwnode_get_phy_node() fwnode_mdio_find_device() acpi_get_local_address() First one helps in connecting phy to phylink instance. Next three helps in getting phy_id and registering phy to mdiobus Next two help in finding a phy on a mdiobus. Next one helps in getting phy_node from a fwnode. Last one is used to get local address from _ADR object. Corresponding OF functions are refactored. Tested-on: LX2160ARDB Changes in v9: - merged some minimal changes requested in the wording of the commit messages - fixed some build problems in patch 8/15 by moving the removal of of_find_mii_timestamper from patch 8/15 to 9/15. Changes in v8: - fixed some checkpatch warnings/checks - included linux/fwnode_mdio.h in fwnode_mdio.c (fixed the build warnings) - added fwnode_find_mii_timestamper() and fwnode_mdiobus_phy_device_register() in order to get rid of the cycle dependency. - change to 'depends on (ACPI || OF) || COMPILE_TEST (for FWNODE_MDIO) - remove the fwnode_mdiobus_register from fwnode_mdio.c since it introduces a cycle of dependencies. Changes in v7: - correct fwnode_mdio_find_device() description - check NULL in unregister_mii_timestamper() - Call unregister_mii_timestamper() without NULL check - Create fwnode_mdio.c and move fwnode_mdiobus_register_phy() - include fwnode_mdio.h - Include headers directly used in acpi_mdio.c - Move fwnode_mdiobus_register() to fwnode_mdio.c - Include fwnode_mdio.h - Alphabetically sort header inclusions - remove unnecassary checks Changes in v6: - Minor cleanup - fix warning for function parameter of fwnode_mdio_find_device() - Initialize mii_ts to NULL - use GENMASK() and ACPI_COMPANION_SET() - some cleanup - remove unwanted header inclusion - remove OF check for fixed-link - use dev_fwnode() - remove useless else - replace of_device_is_available() to fwnode_device_is_available() Changes in v5: - More cleanup - Replace fwnode_get_id() with acpi_get_local_address() - add missing MODULE_LICENSE() - replace fwnode_get_id() with OF and ACPI function calls - replace fwnode_get_id() with OF and ACPI function calls Changes in v4: - More cleanup - Improve code structure to handle all cases - Remove redundant else from fwnode_mdiobus_register() - Cleanup xgmac_mdio_probe() - call phy_device_free() before returning Changes in v3: - Add more info on legacy DT properties "phy" and "phy-device" - Redefine fwnode_phy_find_device() to follow of_phy_find_device() - Use traditional comparison pattern - Use GENMASK - Modified to retrieve reg property value for ACPI as well - Resolved compilation issue with CONFIG_ACPI = n - Added more info into documentation - Use acpi_mdiobus_register() - Avoid unnecessary line removal - Remove unused inclusion of acpi.h Changes in v2: - Updated with more description in document - use reverse christmas tree ordering for local variables - Refactor OF functions to use fwnode functions ==================== Signed-off-by: -

Introduce fwnode_mdiobus_register_phy() to register PHYs on the mdiobus. From the compatible string, identify whether the PHY is c45 and based on this create a PHY device instance which is registered on the mdiobus. Along with fwnode_mdiobus_register_phy() also introduce fwnode_find_mii_timestamper() and fwnode_mdiobus_phy_device_register() since they are needed. While at it, also use the newly introduced fwnode operation in of_mdiobus_phy_device_register(). Signed-off-by:

The commit 8532f613 ("net: stmmac: introduce MSI Interrupt routines for mac, safety, RX & TX") introduced the converity warnings:- 1. Unused value (UNUSED_VALUE) assigned_value: Assigning value REQ_IRQ_ERR_MAC to irq_err here, but that stored value is not used. 2. Unused value (UNUSED_VALUE) assigned_value: Assigning value REQ_IRQ_ERR_NO to irq_err here, but that stored value is overwritten before it can used. 3. Unused value (UNUSED_VALUE) assigned_value: Assigning value REQ_IRQ_ERR_WOL to irq_err here, but that stored value is not used. Fixed these by removing the unnecessary value assignments.

It has been reported that on RTL8106e the link-up interrupt may be significantly delayed if the user enables ASPM L1. Per default ASPM is disabled. The change leaves L1 enabled on the PCIe link (thus still allowing to reach higher package power saving states), but the NIC won't actively trigger it. Reported-by:

This enables TX NAPI for those devices that didn't use it previously, so that we can eventually rip out the qdio layer's internal interrupt machinery. Other than that it's just the normal mix of minor improvements and cleanups. ==================== Signed-off-by: -

Julian Wiedmann authored
Maintaining a pointer inside the aob's user-definable area is fragile and unnecessary. At this stage we only need it to overload the buffer's state field, and to access the buffer's TX queue. The first part is easily solved by tracking the aob's state within the aob itself. This also feels much cleaner and self-contained. For enabling the access to the associated TX queue, we can store the queue's index in the aob. Signed-off-by:

Julian Wiedmann authored
With commit 396c1004 ("s390/qdio: let driver manage the QAOB") a pending TX buffer now has access to its associated QAOB during TX completion processing. We can thus reduce the amount of work & state propagation that needs to be done by qeth_qdio_handle_aob(). Move all this logic into the respective TX completion paths. Doing so even allows us to determine more precise TX_NOTIFY_* values via qeth_compute_cq_notification(aob->aorc, ...). Signed-off-by:
