2017-06-05iwlwifi: mvm: support init flow debuggingLiad Kaufman
In case an assert happens on init flow, the current driver powers down the NIC, except if iwlmvm modparam init_dbg=1, and only on very specific flows. Extend this capability to cover most failure cases by keeping track of what init configurations have been completed. This way, we can allow NOT powering down the NIC, while making sure that when the driver is removed we don't try to free resources that haven't been allocated. (This can result in a kernel panic.)

2017-06-05iwlwifi: mvm: fix firmware debug restart recordingEmmanuel Grumbach
When we want to stop the recording of the firmware debug and restart it later without reloading the firmware we don't need to resend the configuration that comes with host commands. Sending those commands confused the hardware and led to an NMI 0x66. Change the flow as following: * read the relevant registers (DBGC_IN_SAMPLE, DBGC_OUT_CTRL) * clear those registers * wait for the hardware to complete its write to the buffer * get the data * restore the value of those registers (to restart the recording) For early start (where the configuration is already compiled in the firmware), we don't need to set those registers after the firmware has been loaded, but only when we want to restart the recording without having restarted the firmware.

2017-06-05iwlwifi: mvm: rs: start using LQ command colorGregory Greenman
Up until now, the driver was comparing the rate reported by the FW and the rate of the latest LQ command to avoid processing data belonging to the old LQ command. Recently, FW changed the meaning of the initial rate field in tx response and it holds the actual rate (which is not necessarily the initial rate of LQ's rate table). Use instead LQ cmd color to be able to filter out tx responses/BA notifications which where sent during earlier LQ commands' time frame. This fixes some throughput degradation in noisy environments.

2017-06-05net-next: stmmac: dwmac-sun8i: ensure the EPHY is properly resetedIcenowy Zheng
The EPHY may be already enabled by bootloaders which have Ethernet capability (e.g. current U-Boot). Thus it should be reseted properly before doing the enabling sequence in the dwmac-sun8i driver, otherwise the EMAC reset process may fail if no cable is plugged, and then fail the dwmac-sun8i probing. Tested on Orange Pi PC, One and Zero. All the boards fail to have dwmac-sun8i probed with "EMAC reset timeout" without cable plugged before, and with this fix they're now all able to successfully probe the EMAC without cable plugged and then use the connection after a cable is hot-plugged in.

2017-06-04qed: VFs to try utilizing the doorbell barMintz, Yuval
VFs are currently not mapping their doorbell bar, instead relying on the small doorbell window they have in their limited regview bar. In order to increase the number of possible Tx connections [queues] employeed by VF past 16, we need to start using the doorbell bar if one such is exposed - VF would communicate this fact to PF which would return the size-bar internally configured into chip, according to which the VF would decide whether to actually utilize the doorbell bar.

This adds the infrastructure for supporting VFs that want to open multiple transmission queues on the same queue-zone. At this point, there are no VFs that actually request this functionality, but later patches would remedy that. a. VF and PF would communicate the capability during ACQUIRE; Legacy VFs would continue on behaving as they do today b. PF would communicate number of supported CIDs to the VF and would enforce said limitation c.

2017-06-04qed: Make VF legacy a bitfieldMintz, Yuval
Until now we used to have a single VF legacy compatibility mode, one that affected the place of the Rx producers of those VFs [mostly]. As PF would soon support allocating CIDs for VFs instead of having a static CID<->queue configuration for them, we'll need to have an additional legacy mode since existing VFs would need to continue on using the older mode of operation. Change the infrastrucutre so that the legacy would be able to indicate which of the legacy behaviors is needed for a given VF.

2017-06-04qed: Assign a unique per-queue index to queue-cidMintz, Yuval
When a queue-cid is allocated, assign an index inside that's CID's queue-zone. For PFs and VFS, this number is going to be unique and derive from a per-queue-zone bitmap, while for PF's VFs queues the number is currently going to constant; Later, we'd add the capability of a VF to communicate such an index to its PF.

2017-06-04qed: Pass vf_params when creating a queue-cidMintz, Yuval
We're going to need additional information for queue-cids that a PF creates for its VFs, so start by refactoring existing logic used for initializing said struct into receiving a structure encapsulating the VF-specific information that needs to be provided. This also introduces QED_QUEUE_CID_SELF - each queue-cid would hold an indication to whether it belongs to the hw-function holding it [whether that's a PF or a VF], or else what's the VF id it belongs to.

2017-06-04qed: Add bitmaps for VF CIDsMintz, Yuval
Each PF has a bitmap for its own ranges of CIDs, to allow easy grabbing of an available CID when such is needed. But VFs are not using the same mechanism, instead relying on hard-coded CIDs [ queue-index == cid ]. As an infrastructure step toward increasing number of CIDs of VFs, the PF is going to maintain bitmaps for the VF CIDs as well - the bitmaps would be per-VF and the ranges would be the same [in HW all VFs of a given PF have the same mapping of CIDs, and the HW is capable of distinguishing between those according to the VF index] Signed-off-by: Yuval Mintz <Yuval.Mintz@cavium.com> Signed-off-by: David S.
