Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-12-06 This series contains updates to i40e and i40evf. Shannon provides several patches to cleanup and fix i40e. First removes an unneeded break statement in i40e_vsi_link_event(). Then removes some debug messages that really do not give any useful information and ends up getting printed every service_task loop, which fills the logfile with noise when AQ tracing is enabled. Updates the aq_cmd arguments to use %i which is much more forgiving and user friendly than the more restrictive %x, or %d. Fixes the netdev_stat macro, where the old xxx_NETDEV_STAT() macro was defined long before the newer rtnl_link_stats64 came into being, and just never got updated. Getting the pf_id from the function number had an issue when when the PF was setup in passthru mode, the PCI bus/device/function was virtualized and the number in the VM is different from the number in the bare metal. This caused HW configuration issues when the wrong pf_id was used to set up the HMC and other structures. The PF_FUNC_RID register has the real bus/device/function information as configured by the BIOS, so use that for a better number. Carolyn adds additional text description for the base pf0 and flow director generated interrupts, since these interrupts are difficult to distinguish per port on a multi-function device. Jacob resolves an issue related to images with multiple PFs per physical port. We cannot fully support 1588 PTP features, since only one port should control (i.e. write) the registers at a time. Doing so can cause interference of functionality. Anjali provides several updates to i40e, first adds the Virtual Channel OP event opcode for CONFIG_RSS, so that the Virtual Channel state machine can properly decipher status change events. Then updates the driver to add (and use) i40e_is_vf macro for future expansion when new VF MAC types get added. Adds new update VSI flow to accommodate a firmware dix with VSI loopback mode. All VSIs on a VEB should either have loopback enabled or disabled, a mixed mode is not supported for a VEB. Since our driver supports multiple VSIs per PF that need to talk to each other make sure to enable Loopback for the PF and FDIR VSI as well. Mitch provides a couple of i40e and i40evf patches. First updates i40evf init code more adept at handling when multiple VFs attempt to initialize simultaneously. Joe Perches provides a i40e patch which resolves a compile warning about about frame size being larger than 2048 bytes by reducing the stack use by using kmemdup and not using a very large struct on the stack. v2: - Dropped patch 13 & 14 while Mitch reworks the patches based on feedback from Ben Hutchings, probably the tryptophan in the turkey is to blame for the delay... - Added Joe Perches patch which resolves a compile warning about frame size ==================== Signed-off-by: David S.
