2015-10-08i40evf: detect reset more reliablyMitch Williams
Using VFGEN_RSTAT to detect a VF reset is an endeavor that is fraught with peril. It's entirely too easy to miss a reset because none of the bits are sticky. By the time the VF driver reads the register, the reset may have been processed and cleaned up by the PF driver, leaving the register in the same state that it was before the reset. Instead, detect a reset with the VF_ARQLEN register. When the VF is reset, the enable bit in this register is cleared, and it stays cleared until the VF driver processes the reset and re-enables the admin queue. Because we now deal with multiple registers in the reset and watchdog tasks, rename the rstat_val variable to reg_val.

2015-10-08i40e/i40evf: Explicitly assign enum index for VSI typeSerey Kong
Ran into an issue where PF's VSI type list was different from VF's, which was resulted in different enum index. The VSI type list can be different depending on what build flag is used for PF and VF. The change is to explicitly assign enum index for each VSI type so that PF and VF always reference to the same VSI type event if the enum lists are different.

2015-10-07i40evf: propagate interrupt allocation failureMitch Williams
Lower level functions are properly reporting errors, and higher-level functions are correctly responding to errors, but the errors aren't actually getting through.

2015-10-07i40e/i40evf: fix unicast mac address addShannon Nelson
When using something like "ip maddr add ..." to add another unicast mac address to the netdev, the mac address comes into the set_rx_mode handler in the multicast list whether it is a unicast or multicast address. This was confusing the code when it was trying to search for addresses that needed to be deleted from the VSI, because it was looking for the VSI unicast address in the netdev unicast list. The result was that a new unicast address would get added to the VSI list and then immediately removed, and would never actually make it down into the hardware. This patch removes the separation from unicast and multicast in the search for filters to be deleted. It also simplifies the logic a little with a jump to the bottom of the loop when an address is found. Now it doesn't matter which netdev list the address is hiding in, we'll check them all.

2015-10-03i40evf: don't blow away MAC addressMitch Williams
Under certain circumstances, we can get an extra VF_RESOURCES message from the PF driver at runtime. When this happens, we need to parse it because our VSI may have changed out from underneath us, and that will affect our relationship with the PF driver. However, parsing the resources message also blows away our current MAC address in the hardware struct, usually with all zeros. When this happens, the next time the interface is opened, it will have no MAC address and will a) not work and b) complain. Fix this issue by restoring the current MAC address from the netdev struct after we parse the resource message.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-09-30 This series contains updates to i40e and i40evf only. Vasily Averin provides a couple of rtnl lock/unlock fixes for both i40e and i40evf. Shannon provides several updates and fixes, first fixes up a type clash in i40e_aq_rc_to_posix(), where the error codes are signed values, so we need to treat them as such. Then fixes up a padding issue where an extra byte is added in i40e_aqc_get_cee_dcb_cfg_v1_resp to directly acknowledge the padding. Updated i40e to keep debugfs register read and writes from accessing outside of the io-remapped space. Added support and device id for another 20 GbE device. Jesse fixes the transmit hand workaround code for ARM that was causing Tx hangs to still occur occasionally when there really was no hang. Then fixed the receive dropped counter to show up in netstat interface. Refactor the interrupt enable function since it was always making the caller add the base_vector from the VSI struct which is already passed to the function. Fix kbuild warnings found in 0day build infrastructure by adding a harmless cast to a dev_info(), also fix 32 bit build warnings found by sparse. Greg fixed a configuration error that results if a port VLAN is set for a VF before the VF driver is loaded, so that when the VF driver is loaded the port VLAN is ignored. Mitch fixes the use of QOS field consistently in i40e_ndo_set_vf_port_vlan(). Modified the init timing of the driver to increase stability on load/unload and SR-IOV enable/disable cycles. Anjali updates i40e to not collect VEB stats if they are disabled in the hardware for performance reasons. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2015-09-30i40evf: tweak init timingMitch Williams
This patch tweaks the init timing of the driver just a little bit to increase stability on load/unload and SR-IOV enable/disable cycles. First, run the init_task loop a little quicker in order to reduce overall init time. Second, stagger the start of the init task based on the device's PCIe function ID. This lessens the impact on the firmware when a whole bunch of VFs are initialized simultaneously, e.g. enabling SR-IOV without the VF driver blacklisted. For single VFs assigned to VMs this will have no effect as the function ID will always be 0.

2015-07-23i40e: use BIT and BIT_ULL macrosJesse Brandeburg
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.

2015-07-23i40e: clean up error status messagesShannon Nelson
Clean up a little confusion in reporting error status in phy and fcoe setup error reports by separating the return status from the AQ error. Add two decoder functions to make this easier.

2015-07-23i40evf: support virtual channel API version 1.1Mitch Williams
Store off the PF's API version, then use it to determine whether or not to send it our capabilities. Change the version checking to allow for PF drivers with lower API versions than our current version, so we can still talk to PF drivers over the 1.0 API.

2015-07-23i40evf: handle big resetsMitch Williams
The most common type of reset that the VF will encounter is a PF reset that cascades down into a VF reset for each VF. In this case, the VF will always be assigned the same VSI and recovery is fairly simple. However, in the case of 'bigger' resets, such as a Core or EMP reset, when the device is reinitialized, it's probable that the VF will NOT get the same VSI. When this happens, the VF will not be able to recover, as it will continue to request resources for its original VSI. Add an extra state to the admin queue state machine so that the driver can re-request its configuration information at runtime. During reset recovery, set this bit in the aq_required field, and fetch the (possibly new) configuration information before attempting to bring the driver back up. Since the driver doesn't know what kind of reset it has encountered, this step is done even for a PF reset, but it doesn't hurt anything - it just gets the same VSI back.

2015-07-23i40e/i40evf: add macros for virtual channel API version and device capabilityMitch Williams
Now that we've rolled the virtual channel API version to 1.1, add some macros to test what version is being used by our partner in crime. For the VF, add some macros to determine what our device capabilities are.
