git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series contains updates to e1000e, igb, i40e and i40evf Anjali provides i40e fix to remove the ATR filter on RST as well as FIN packets. Cleans up add_del_fdir() because it was used and implemented only for the add, so change the name and drop a parameter. Adds the ability to drop a flow if we wanted to and adds a flow director message level to be used for flow director specific messages. Mitch fixes an issue on i40evf where the Tx watchdog handler was causing an oops when sending an admin queue message to request a reset because the admin queue functions use spinlocks. Greg provides a change to i40e to make the alloc and free queue vector calls orthogonal. Shannon fixes i40e to verify the eeprom checksum and firmware CRC status bits, and shutdown the driver if they fail. This change stops the processing of traffic, but does not kill the PF netdev so that the NVMUpdate process still has a chance at fixing the image. Also provides a fix to make sure the VSI has a netdev before trying to use it in the debugfs netdev_ops commands. Jakub Kicinski provides patches for e1000e and igb to fix a number issues found in the PTP code. v2: - drop patch 11 "i40e: Add a fallback debug flow for the driver" from the series based on feedback from David Miller ==================== Signed-off-by: David S.

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 Perla3-58/+154
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 <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2014-03-28Input: synaptics - add manual min/max quirkBenjamin Tissoires1-0/+47
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.

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.
