Broadcom tags inserted by Broadcom switches put a 4 byte header after the MAC SA and before the EtherType, which may look like some sort of 0 length LLC/SNAP packet (tcpdump and wireshark do think that way). With ACS enabled in stmmac the packets were truncated to 8 bytes on reception, whereas clearing this bit allowed normal reception to occur. In order to make that possible, we need to pass a net_device argument to the different core_init() functions and we are dependent on the Broadcom tagger padding packets correctly (which it now does). To be as little invasive as possible, this is only done for gmac1000 when the network device is DSA-enabled (netdev_uses_dsa() returns true).

Commit ccfdec90 ("macsec: Add support for GCM-AES-256 cipher suite") changed a few values in the uapi headers for MACsec. Because of existing userspace implementations, we need to preserve the value of MACSEC_DEFAULT_CIPHER_ID. Not doing that resulted in wpa_supplicant segfaults when a secure channel was created using the default cipher. Thus, swap MACSEC_DEFAULT_CIPHER_{ID,ALT} back to their original values. Changing the maximum length of the MACSEC_SA_ATTR_KEY attribute is unnecessary, as the previous value (MACSEC_MAX_KEY_LEN, which was 128B) is large enough to carry 32-bytes keys. This patch reverts MACSEC_MAX_KEY_LEN to 128B and restores the old length check on MACSEC_SA_ATTR_KEY.

This patch introduces an alternative way of obtaining resources - via ACPI tables provided by firmware. Enabling coexistence with the DT support, in addition to the OF_*->device_*/fwnode_* API replacement, required following steps to be taken: * Add mvpp2_acpi_match table * Omit clock configuration and obtain tclk from the property - in ACPI world, the firmware is responsible for clock maintenance. * Disable comphy and syscon handling as they are not available for ACPI. * Modify way of obtaining interrupts - use newly introduced fwnode_irq_get() routine * Until proper MDIO bus and PHY handling with ACPI is established in the kernel, use only link interrupts feature in the driver. For the RGMII port it results in depending on GMAC settings done during firmware stage. * When booting with ACPI MVPP2_QDIST_MULTI_MODE is picked by default, as there is no need to keep any kind of the backward compatibility. Moreover, a memory region used by mvmdio driver is usually placed in the middle of the address space of the PP2 network controller. The MDIO base address is obtained without requesting memory region (by devm_ioremap() call) in mvmdio.c, later overlapping resources are requested by the network driver, which is responsible for avoiding a concurrent access. In case the MDIO memory region is declared in the ACPI, it can already appear as 'in-use' in the OS. Because it is overlapped by second region of the network controller, make sure it is released, before requesting it again. The care is taken by mvpp2 driver to avoid concurrent access to this memory region. Signed-off-by: NMarcin Wojtas <mw@semihalf.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

'port_count' field of the mvpp2 structure holds an overall amount of available ports, based on DT nodes status. In order to be prepared to support other HW description, obtain the value by incrementing it upon each successful port initialization. This allowed for simplifying port indexing in the controller's private array, whose size is now not dynamically allocated, but fixed to MVPP2_MAX_PORTS. This patch simplifies creating and filling list of enabled ports and is a part of the preparation for adding ACPI support in the mvpp2 driver.

Until now there were two very similar functions allowing to get Linux IRQ number from ACPI handle (acpi_irq_get()) and OF node (of_irq_get()). The first one appeared to be used only as a subroutine of platform_irq_get(), which (in the generic code) limited IRQ obtaining from _CRS method only to nodes associated to kernel's struct platform_device. This patch introduces a new helper routine - fwnode_irq_get(), which allows to get the IRQ number directly from the fwnode to be used as common for OF/ACPI worlds. It is usable not only for the parents fwnodes, but also for the child nodes comprising their own _CRS methods with interrupts description. In order to be able o satisfy compilation with !CONFIG_ACPI and also simplify the new code, introduce a helper macro (ACPI_HANDLE_FWNODE), with which it is possible to reach an ACPI handle directly from its fwnode.

由 Ido Schimmel 提交于
In commit fc922bb0 ("mlxsw: spectrum_router: Use one LPM tree for all virtual routers") I tried to make sure only used prefix lengths are present in the LPM tree shared between all virtual routers. However, this optimization had to be removed in commit a69518cf ("mlxsw: spectrum_router: Avoid expensive lookup during route removal"), since determining the used prefix lengths required us to traverse all the active virtual routers, which could result in a hung task depending on the number of VRFs and whether routes were removed due to abort or not. Re-introduce the optimization by moving the prefix usage accounting from the virtual routers to the LPM tree, as this accounting is only used in order to determine the tree's structure. To make the sharing of the trees more explicit, the two trees (for IPv4 and IPv6) are stored in the shared router struct and upon the creation of a virtual router it is immediately bound to both.

Currently, each FIB (IPv4 / IPv6) in a virtual router holds a prefix usage that is used to choose a matching LPM tree, but also to check if the FIB is empty, so that the LPM tree could be unbound. Next patches will remove the reliance on the per-FIB prefix usage for LPM tree matching. Keeping it only to check if the FIB is empty is a waste, since we can use the nodes ({Prefix, Length}) list instead.
