In compat mode SIOC{G,S}IFBR ioctls were only supporting BRCTL_GET_VERSION returning an artificially version to spur userland tool to use SIOCDEVPRIVATE instead. But some userland tools ignore that and use SIOC{G,S}IFBR unconditionally as seen with busybox's brctl.

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() for DT users only. While at it propagate error code in case request_irq() fails instead of returning -EBUSY. Signed-off-by:

We are seeing spurious wakeup caused by Intel 7560 WWAN on AMD laptops. This prevent those laptops to stay in s2idle state. >From what I can understand, the intention of ipc_pcie_suspend() is to put the device to D3cold, and ipc_pcie_suspend_s2idle() is to keep the device at D0. However, the device can still be put to D3hot/D3cold by PCI core. So explicitly let PCI core know this device should stay at D0, to solve the spurious wakeup. Signed-off-by:

The blamed commit changed the vlan used by the host ports to be 4095 instead of 0. Because of this change the following issues are seen: - when the port is probed first it was adding an entry in the MAC table with the wrong vlan (port->pvid which is default 0) and not HOST_PVID - when the port is removed from a bridge, it was using the wrong vlan to add entries in the MAC table. It was using the old PVID and not the HOST_PVID This patch fixes this two issues by using the HOST_PVID instead of port->pvid. Fixes: 6d2c186a ("net: lan966x: Add vlan support.") Signed-off-by:

Michael Chan authored
CQE coalescing mode is the same as the timer reset coalescing mode on Broadcom devices. Currently this mode is always enabled if it is supported by the device. Restructure the code slightly to support dynamically changing this mode. Add a flags field to struct bnxt_coal. Initially, the CQE flag will be set for the RX and TX side if the device supports it. We need to move bnxt_init_dflt_coal() to set up default coalescing until the capability is determined. Reviewed-by:

Change the case that sends packets with "too short inner packet" to include part of ethernet header, to make the trap to be triggered due to the correct reason. According to ASIC arch, the trap is triggered if overlay packet length is less than 18B, and the minimum inner packet should include source MAC and destination MAC. Till now the case passed because one of the reserved bits in VxLAN header was used. This issue was found while adding an equivalent test for IPv6. Signed-off-by:
