2019-09-12net: dsa: microchip: add ksz9567 to ksz9477 driverGeorge McCollister
Add support for the KSZ9567 7-Port Gigabit Ethernet Switch to the ksz9477 driver. The KSZ9567 supports both SPI and I2C. Oddly the ksz9567 is already in the device tree binding documentation.

2019-09-11ixgbe: fix double clean of Tx descriptors with xdpIlya Maximets
Tx code doesn't clear the descriptors' status after cleaning. So, if the budget is larger than number of used elems in a ring, some descriptors will be accounted twice and xsk_umem_complete_tx will move prod_tail far beyond the prod_head breaking the completion queue ring. Fix that by limiting the number of descriptors to clean by the number of used descriptors in the Tx ring. 'ixgbe_clean_xdp_tx_irq()' function refactored to look more like 'ixgbe_xsk_clean_tx_ring()' since we're allowed to directly use 'next_to_clean' and 'next_to_use' indexes.

2019-09-11ixgbe: Prevent u8 wrapping of ITR value to something less than 10usAlexander Duyck
There were a couple cases where the ITR value generated via the adaptive ITR scheme could exceed 126. This resulted in the value becoming either 0 or something less than 10. Switching back and forth between a value less than 10 and a value greater than 10 can cause issues as certain hardware features such as RSC to not function well when the ITR value has dropped that low.

2019-09-11i40e: fix potential RX buffer starvation for AF_XDPMagnus Karlsson
When the RX rings are created they are also populated with buffers so that packets can be received. Usually these are kernel buffers, but for AF_XDP in zero-copy mode, these are user-space buffers and in this case the application might not have sent down any buffers to the driver at this point. And if no buffers are allocated at ring creation time, no packets can be received and no interrupts will be generated so the NAPI poll function that allocates buffers to the rings will never get executed. To rectify this, we kick the NAPI context of any queue with an attached AF_XDP zero-copy socket in two places in the code. Once after an XDP program has loaded and once after the umem is registered. This take care of both cases: XDP program gets loaded first then AF_XDP socket is created, and the reverse, AF_XDP socket is created first, then XDP program is loaded.

2019-09-11iavf: fix MAC address setting for VFs when filter is rejectedStefan Assmann
Currently iavf unconditionally applies MAC address change requests. This brings the VF in a state where it is no longer able to pass traffic if the PF rejects a MAC filter change for the VF. A typical scenario for a rejected MAC filter is for an untrusted VF to request to change the MAC address when an administratively set MAC is present. To keep iavf working in this scenario the MAC filter handling in iavf needs to act on the PF reply regarding the MAC filter change. In the case of an ack the new MAC address gets set, whereas in the case of a nack the previous MAC address needs to stay in place.

2019-09-11net: stmmac: implement support for passive mode converters via dtAlexandru Ardelean
In-between the MAC & PHY there can be a mode converter, which converts one mode to another (e.g. GMII-to-RGMII). The converter, can be passive (i.e. no driver or OS/SW information required), so the MAC & PHY need to be configured differently. For the `stmmac` driver, this is implemented via a `mac-mode` property in the device-tree, which configures the MAC into a certain mode, and for the PHY a `phy_interface` field will hold the mode of the PHY. The mode of the PHY will be passed to the PHY and from there-on it work in a different mode. If unspecified, the default `phy-mode` will be used for both.

Currently when hns3 driver configures the tm shaper to limit bandwidth below 20Mbit using the parameters calculated by hclge_shaper_para_calc(), the actual bandwidth limited by tm hardware module is not accurate enough, for example, 1.28 Mbit when the user is configuring 1 Mbit. This patch adjusts the ir_calc to be closer to ir, and always calculate the ir_b parameter when user is configuring a small bandwidth. Also, removes an unnecessary parenthesis when calculating denominator.
