i40e: use BIT and BIT_ULL macros

2015-07-23T12:33:55Z

Use macros for abstracting (1 << foo) to BIT(foo) and (1ULL << foo64) to BIT_ULL(foo64) in order to match better with kernel requirements. NOTE: the adminq_cmd.h file was not modified on purpose because of the dependency upon firmware for that file.

i40e: start up in VEPA mode by default

2015-06-05T03:10:30Z

The patch fixes a bug in the default configuration which prevented a software bridge loaded on the PF interface from working correctly because broadcast packets are incorrectly looped back. Fix the general case, by loading the driver in VEPA mode Until a VF or VMDq VSI is added. This way loopback on the Main VSI is turned off until needed and can resolve the issue of unnecessary reflection for users that do not have VF or VMDq VSIs setup. The driver must now coordinate the loopback setting for the Flow Director (FDIR) VSI to make sure it is in sync with the current VEB or VEPA mode setting. The user can still switch bridge modes from the bridge commands and choose to be in VEPA mode with VF VSIs. Because of hardware requirements, the call to switch to VEB mode when no VF/VMDqs are present will be rejected. NOTE: This patch uses BIT_ULL as that is preferred going forward, a followup patch in the lower priority queue to net-next will fix up the remaining 1 << usages.

i40e: enable user dump of internal hardware state

2015-04-15T03:14:58Z

This is a feature to enable better debugging of user reported issues by allowing a bash script to acquire information about the internal hardware state. The data output to the kernel log is collected by the script and can then be sent to Intel. This is a critical debugging feature for helping us interpret and reproduce complex customer setups.

i40e: add MAC printing to debugfs dump VSI

2015-03-09T17:53:19Z

Print the LAN, SAN, and Port MACs for the VSI if debugfs command dump VSI is used on the PF's VSI. Example output: [260221.871244] i40e 0000:04:00.0: MAC address: 68:05:ca:26:15:e0 SAN MAC: 00:00:00:00:02:00 Port MAC: 68:05:ca:26:15:e3 Change-ID: I0b393113dfb5ee7ff4f9e5227e4177885f0cc15e Signed-off-by: Shannon Nelson Signed-off-by: Jeff Kirsher

i40e: Fix inconsistent use of PF/VF vs pf/vf

2015-03-09T12:20:47Z

Joe Perches pointed out that we were inconsistent in the use of PF vs pf or VF vs vf in our driver code. Since acronyms are usually capitalized to denote that it is an acronym, changed all references to be consistent throughout the code. Reported-by: Joe Perches Signed-off-by: Jeff Kirsher

i40e: Remove "hello world" strings from i40e driver

2015-03-09T12:20:44Z

While using the Linux "strings" command I found these two strings in the driver. There's no need for them and they're kinda silly. Change-ID: I4e19b02983d48b631e9a9979f49790492845f221 Signed-off-by: Greg Rose Signed-off-by: Jeff Kirsher

i40e: Add support for getlink, setlink ndo ops

2015-02-25T05:57:05Z

Add support for bridge offload ndo_ops getlink and setlink to enable bridge hardware mode as per the mode set via IFLA_BRIDGE_MODE. The support is only enabled in case of a PF VSI and not available for any other VSI type. By default the i40e driver inserts a bridge as part of the bring-up when a FDIR type VSI and/or a FCoE VSI is created. This bridge is created in VEB mode by default i.e. after creating the bridge using "Add VEB" AQ command the loopback for the PF's default VSI is enabled. The patch adds capability where all the VSIs created as downlink to the bridge inherits the loopback property and enables loopback only if the uplink bridge is operating in VEB mode. Hence, there is no need to explicitly enable loopback as part of allocating resources for SR-IOV VFs and call to do that has been removed. In case a user-request is made either via "bridge" utility or using the bridge netlink interface that requires to change the hardware bridge mode then that would require a PF reset and rebuild of the switch hierarchy. Also update the copyright year. Change-ID: I4d78fc1c83158efda29ba7be92239b74f75d6d25 Signed-off-by: Neerav Parikh Tested-By: Jim Young Signed-off-by: Jeff Kirsher

i40e: rename debugfs clear_stats option

2015-02-24T01:11:55Z

Change debugfs command from "clear_stats pf" to "clear_stats port" to be clearer what the action is. Also, limit the action to the base PF, not the NPAR partitions. Change-ID: I22aa39c0962d83a83a985097b1000ed7f8c66f3f Signed-off-by: Shannon Nelson Tested-by: Jim Young Signed-off-by: Jeff Kirsher
