net: ethernet: ave: Fix MAC to be in charge of PHY PM

2022-10-27T03:21:34Z

The phylib callback is called after MAC driver's own resume callback is called. For AVE driver, after resuming immediately, PHY state machine is in PHY_NOLINK because there is a time lag from link-down to link-up due to autoneg. The result is WARN_ON() dump in mdio_bus_phy_resume(). Since ave_resume() itself calls phy_resume(), AVE driver should manage PHY PM. To indicate that MAC driver manages PHY PM, set phydev->mac_managed_pm to true to avoid the unnecessary phylib call and add missing phy_init_hw() to ave_resume().

net: netsec: fix error handling in netsec_register_mdio()

2022-10-21T04:08:41Z

If phy_device_register() fails, phy_device_free() need be called to put refcount, so memory of phy device and device name can be freed in callback function. If get_phy_device() fails, mdiobus_unregister() need be called, or it will cause warning in mdiobus_free() and kobject is leaked.

net: drop the weight argument from netif_napi_add

2022-09-29T01:57:14Z

We tell driver developers to always pass NAPI_POLL_WEIGHT as the weight to netif_napi_add(). This may be confusing to newcomers, drop the weight argument, those who really need to tweak the weight can use netif_napi_add_weight().

net: ethernet: move from strlcpy with unused retval to strscpy

Follow the advice of the below link and prefer 'strscpy' in this subsystem. Conversion is 1:1 because the return value is not used. Generated by a coccinelle script.

ethernet: netsec: Use platform_get_irq() to get the interrupt

2021-12-27T12:22:19Z

platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static allocation of IRQ resources in DT core code, this causes an issue when using hierarchical interrupt domains using "interrupts" property in the node as this bypasses the hierarchical setup and messes up the irq chaining. In preparation for removal of static setup of IRQ resource from DT core code use platform_get_irq(). Signed-off-by: Lad Prabhakar Signed-off-by: David S. Miller

bpf: Let bpf_warn_invalid_xdp_action() report more info

2021-12-13T21:28:27Z

In non trivial scenarios, the action id alone is not sufficient to identify the program causing the warning. Before the previous patch, the generated stack-trace pointed out at least the involved device driver. Let's additionally include the program name and id, and the relevant device name. If the user needs additional infos, he can fetch them via a kernel probe, leveraging the arguments added here.

ethernet: netsec: use eth_hw_addr_set()

2021-10-20T10:41:01Z

Commit 406f42fa0d3c ("net-next: When a bond have a massive amount of VLANs...") introduced a rbtree for faster Ethernet address look up. To maintain netdev->dev_addr in this tree we need to make all the writes to it got through appropriate helpers. Read the address into an array on the stack, then call eth_hw_addr_set().
