Sathya Perla says: ==================== be2net: add vxlan offload support The first patch adds the FW cmds needed to configure the Skyhawk-R chip for supporting VxLAN offloads. The second patch implements the ndo_add/del_vxlan_port() methods and the plumbing for supporting RX/TX csum, TSO and RSS steering offloads for VxLAN traffic. v2 changes: NETIF_F_SG need not be set for hw_enc_features by the driver as it is done by the stack. v3 changes: * Defer FW cmds needed for VxLAN offloads to a workqueue * Reset FW to VxLAN offloads disabled state in the unload path v4 changes: * Revert the usage of workqueue (introduced in v3) to implement ndo_add/del_vxlan_port() as it is currently not needed (none of the FW cmd calls sleep.)

2014-03-28be2net: add FW cmds needed for VxLAN offloadsSathya Perla
This patch adds support for the FW cmds needed for VxLAN offloads on Skyhawk-R: 1) The VxLAN UDP port needs to be configured via the port-desc of SET_PROFILE_CONFIG_v1 cmd. This patch re-factors the be_set_profile_config() code (used so far only for setting VF QoS) to be used to set any type of descriptor. 2) The MANAGE_IFACE_FILTERS cmds is needed to convert a normal interface into a tunnel interface. This allows for RSS to work even on the inner TCP/UDP headers of VxLAN traffic. Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2014-03-28Input: synaptics - add manual min/max quirkBenjamin Tissoires
The new Lenovo Haswell series (-40's) contains a new Synaptics touchpad. However, these new Synaptics devices report bad axis ranges. Under Windows, it is not a problem because the Windows driver uses RMI4 over SMBus to talk to the device. Under Linux, we are using the PS/2 fallback interface and it occurs the reported ranges are wrong. Of course, it would be too easy to have only one range for the whole series, each touchpad seems to be calibrated in a different way. We can not use SMBus to get the actual range because I suspect the firmware will switch into the SMBus mode and stop talking through PS/2 (this is the case for hybrid HID over I2C / PS/2 Synaptics touchpads). So as a temporary solution (until RMI4 land into upstream), start a new list of quirks with the min/max manually set.

2014-03-28i40e: eeprom integrity check on load and emprShannon Nelson
The driver needs to verify the eeprom checksum and firmware crc status bits, and shutdown the driver if they fail. This code stops the processing of traffic, but doesn't kill the PF netdev so that the NVMUpdate process should still have a chance at fixing the image. The eeprom is checked on driver load and after an EMP reset, the latter of which should be generated after an NVMUpdate.

2014-03-28time: Revert to calling clock_was_set_delayed() while in irq contextJohn Stultz
In commit 47a1b796306356f35 ("tick/timekeeping: Call update_wall_time outside the jiffies lock"), we moved to calling clock_was_set() due to the fact that we were no longer holding the timekeeping or jiffies lock. However, there is still the problem that clock_was_set() triggers an IPI, which cannot be done from the timer's hard irq context, and will generate WARN_ON warnings. Apparently in my earlier testing, I'm guessing I didn't bump the dmesg log level, so I somehow missed the WARN_ONs. Thus we need to revert back to calling clock_was_set_delayed().

When the UniMAC block is configured to forward the CRC as part of the Ethernet frame (priv->crc_fwd_en, set by default), enabling the hardware RX checksum block unveiled that the dma_rxchk_bit was never set in the per-packet status bits (dma_flag in bcmgenet_desc_rx). This would make the chksum_ok variable to be never set to 1, and the networking stack would have to compute the packet checksums, which takes a substantial amount of time. In order for the RXCHK block to properly compute the packet checksum in hardware, we also need to set the RBUF_SKIP_FCS bit accordingly.
