This patch adds supports for setting VF trust by host. If specified VF is trusted, then it can enable promisc(include allmulti mode). If a trusted VF enabled promisc, and being untrusted, host will disable promisc mode for this VF. For VF will update its promisc mode from set_rx_mode now, so it's unnecessary to set broadcst promisc mode when initialization or reset.

This patch adds support for spoof check configuration for VFs. When it is enabled, "spoof checking" is done for both mac address and VLAN. For each VF, the HW ensures that the source MAC address (or VLAN) of every outgoing packet exists in the MAC-list (or VLAN-list) configured for RX filtering for that VF. If not, the packet is dropped. Signed-off-by: NJian Shen <shenjian15@huawei.com> Signed-off-by: NHuazhong Tan <tanhuazhong@huawei.com> Signed-off-by: NJakub Kicinski <jakub.kicinski@netronome.com>

This patch adds support to configure VF link properties. The options are auto, enable, and disable. Even if the PF is down, the communication between VFs will be normal if the VFs are set to enable. The commands are as follows: 'ip link set <pf> vf <vf_id> state <auto|enable|disable>' change the VF status 'ip link show' show the setting status Signed-off-by: NYufeng Mo <moyufeng@huawei.com> Signed-off-by: NHuazhong Tan <tanhuazhong@huawei.com> Signed-off-by: NJakub Kicinski <jakub.kicinski@netronome.com>

syzbot reported a warning [1] that triggered after recent Jiri patch. This exposes a bug that we hit already in the past (see commit ff244c6b ("tun: handle register_netdevice() failures properly") for details) tun uses priv->destructor without an ndo_init() method. register_netdevice() can return an error, but will not call priv->destructor() in some cases. Jiri recent patch added one more. A long term fix would be to transfer the initialization of what we destroy in ->destructor() in the ndo_init() This looks a bit risky given the complexity of tun driver. A simpler fix is to detect after the failed register_netdevice() if the tun_free_netdev() function was called already.

Throughout the driver there are several places where we wait indefinitely for DPIO portal commands to be executed, while the portal returns a busy response code. Even though in theory we are guaranteed the portals become available eventually, in practice the QBMan hardware module may become unresponsive in various corner cases.

Read the PHY-specific status register for the current operating mode (speed and duplex) of the PHY. This register reflects the actual mode that the PHY has resolved depending on either the advertisements of autoneg is enabled, or the forced mode if autoneg is disabled. This ensures that phylib's software state always tracks the hardware state. It seems both AR8033 (which uses the AR8031 ID) and AR8035 support this status register. AR8030 is not known at the present time. This patch depends on "net: phy: extract pause mode" and "net: phy: extract link partner advertisement reading".

mdio_device_reset() makes use of the atomic-pretending API flavor for handling the PHY reset GPIO line. I found no hint that mdio_device_reset() is called from atomic context and indeed it uses usleep_range() since long time, so I would assume that it is OK to sleep there. This patch switch to gpiod_set_value_cansleep() in mdio_device_reset(). This is relevant if e.g. the PHY reset line is tied to a I2C GPIO controller. This has been tested on a ZynqMP board running an upstream 4.19 kernel and then hand-ported on current kernel tree.
