2017-04-19i40e: dump VF information in debugfsMitch Williams
Dump some internal state about VFs through debugfs. This provides information not available with 'ip link show'. To use, write "dump vf <id>" to the command file, or just "dump vf" to dump information on all of the VFs.

2017-04-19i40e: Fix support for flow director programming statusAlexander Duyck
This patch fixes an issue I introduced when I converted the code over to using the length field to determine if a descriptor was done or not. It turns out that we are also processing programming descriptors in the Rx path and need to have these processed even though the length field will be 0 on these packets. What will happen with a programming descriptor is that we will receive a descriptor that has the SPH bit set, and the header length and packet length fields cleared. To account for this we should be checking for the bit for split header being set even though we aren't actually using header split. This bit is set in the length field to indicate if a programming descriptor response is contained in the descriptor. Since we don't support header split we don't need to perform the extra checks of using a fixed value for the entire length field. In addition I am moving the function for checking if a filter is a programming status filter into the i40e_txrx.c file since there is no longer support for FCoE it doesn't make sense to keep this file in i40e.h.

2017-04-19i40e/i40evf: Remove VF Rx csum offload for tunneled packetsalice michael
Rx checksum offload for tunneled packets was never being negotiated or requested by VF. This capability was assumed by default and enabled in current hardware for VF. Going forward, this feature needs to be disabled or advanced ptypes should be negotiated with PF in the future.

2017-04-18be2net: VxLAN offload should be re-enabled when only 1 UDP port is leftSriharsha Basavapatna
We disable VxLAN offload when more than 1 UDP port is added to the driver, since Skyhawk doesn't support offload with multiple ports. The existing driver design expects the user to delete all port configurations and create a configuration with a single UDP port for VxLAN offload to be re-enabled. Remove this restriction by tracking the ports added and re-enabling offload when ports get deleted and only 1 port is left.

2017-04-18ftgmac100: Fix potential ordering issue in NAPI pollBenjamin Herrenschmidt
We need to ensure the loads from the descriptor are done after the MMIO store clearing the interrupts has completed, otherwise we might still miss work. A read back from the MMIO register will "push" the posted store and ioread32 has a barrier on weakly aordered architectures that will order subsequent accesses.

Recently, suspend/resume and WOL support are added into mvneta driver. If we enable WOL, then we get some error as below on Marvell BG4CT platforms during suspend: [ 184.149723] dpm_run_callback(): mdio_bus_suspend+0x0/0x50 returns -16 [ 184.149727] PM: Device f7b62004.mdio-mi:00 failed to suspend: error -16 -16 means -EBUSY, phy_suspend() will return -EBUSY if it finds the device has WOL enabled. We fix this issue by properly setting the netdev's power.can_wakeup and power.wakeup, i.e 1. in mvneta_mdio_probe(), call device_set_wakeup_capable() to set power.can_wakeup if the phy support WOL. 2. in mvneta_ethtool_set_wol(), call device_set_wakeup_enable() to set power.wakeup if WOL has been successfully enabled in phy.
