The AFE_RX_LP_COUNTER kept the last 3 bits set, which would not properly clear the EEE LPI mode errors bits.

Writing first to the AFE registers, and then the VCO, RCAL, RC_CAL registers turned out to unveil some spurious MDIO read/write failures which would make the workaround partially applied. The fix is to write first to the VCO, RCAL, RC_CAL registers, and then write to the AFE registers. Signed-off-by: NFlorian Fainelli <f.fainelli@gmail.com> Signed-off-by: NDavid S.

The packet hash can be considered a property of the packet, not just on RX path. This patch changes name of rxhash and l4_rxhash skbuff fields to be hash and l4_hash respectively.

Currently, if a VF's Rx Mode will be configured to support promiscuous mode the PF will comply, causing the VF to actually become promiscuous. This will enable the VF to see all unicast traffic which might be intended for other VMs, which we believe should not be possible. This patch will cause the hypervisor to ignore the VF's request for changes in its Rx mode (other than disabling it), preventing it from becoming promiscuous.

Since we now posses a workqueue dedicated for sriov, the paradigm that sriov- related tasks cannot sleep is no longer correct. The VFOP mechanism was the one previously supporting said paradigm - the sriov related tasks were broken into segments which did not require sleep, and the mechanism re-scheduled the next segment whenever possible. This patch remvoes the VFOP mechanism altogether - the resulting code is a much easier to follow code; The segments are gathered into straight-forward functions which sleep whenever neccessary.

The bnx2x sriov mechanisms were done in the bnx2x slowpath workitem which runs on the bnx2x's workqueue; This workitem is also responsible for the bottom half of interrupt handling in the driver, and specifically it also receives FW notifications of ramrod completions, allowing other flows to progress. The original design of the sriov reltaed-flows was based on the notion such flows must not sleep, since their context is the slowpath workitem. Otherwise, we might reach timeouts - those flows may wait for ramrod completion that will never arrive as the workitem wlll not be re-scheduled until that same flow will be over. In more recent time bnx2x started supporting features in which the VF interface can be configured by the tools accessing the PF on the hypervisor. This support created possible races on the VF-PF lock (which is taken either when the PF is handling a VF message or when the PF is doing some slowpath work on behalf of the VF) which may cause timeouts on the VF side and lags on the PF side. This patch changes the scheme - it creates a new workqueue for sriov related tasks and moves all handling currently done in the slowpath task into the the new workqueue.

The code which is dealing with SRIOV alias GUIDs in the mlx4 IB driver has some logic which operated according to the maximal possible active functions (PF + VFs).

John W. Linville says: ==================== Please pull this batch of wireless updates intended for 3.15! For the mac80211 bits, Johannes says: "This has a whole bunch of bugfixes for things that went into -next previously as well as some other bugfixes I didn't want to rush into 3.14 at this point. The rest of it is some cleanups and a few small features, the biggest of which is probably Janusz's regulatory DFS CAC time code." For the Bluetooth bits, Gustavo says: "One more pull request to 3.15. This is mostly and bug fix pull request, it contains several fixes and clean up all over the tree, plus some small new features." For the NFC bits, Samuel says: "This is the NFC pull request for 3.15. With this one we have: - Support for ISO 15693 a.k.a. NFC vicinity a.k.a. Type 5 tags. ISO 15693 are long range (1 - 2 meters) vicinity tags/cards. The kernel now supports those through the NFC netlink and digital APIs. - Support for TI's trf7970a chipset. This chipset relies on the NFC digital layer and the driver currently supports type 2, 4A and 5 tags. - Support for NXP's pn544 secure firmare download. The pn544 C3 chipsets relies on a different firmware download protocal than the C2 one. We now support both and use the right one depending on the version we detect at runtime. - Support for 4A tags from the NFC digital layer. - A bunch of cleanups and minor fixes from Axel Lin and Thierry Escande." For the iwlwifi bits, Emmanuel says: "We were sending a host command while the mutex wasn't held. This led to hard-to-catch races." And... "I have a fix for a "merge damage" which is not really a merge damage: it enables scheduled scan which has been disabled in wireless.git. Since you merged wireless.git into wireless-next.git, this can now be fixed in wireless-next.git. Besides this, Alex made a workaround for a hardware bug. This fix allows us to consume less power in S3. Arik and Eliad continue to work on D0i3 which is a run-time power saving feature. Eliad also contributes a few bits to the rate scaling logic to which Eyal adds his own contribution. Avri dives deep in the power code - newer firmware will allow to enable power save in newer scenarios. Johannes made a few clean-ups. I have the regular amount of BT Coex boring stuff. I disable uAPSD since we identified firmware bugs that cause packet loss. One thing that do stand out is the udev event that we now send when the FW asserts. I hope it will allow us to debug the FW more easily." Also included is one last iwlwifi pull for a build breakage fix... For the Atheros bits, Kalle says: "Michal now did some optimisations and was able to improve throughput by 100 Mbps on our MIPS based AP135 platform. Chun-Yeow added some workarounds to be able to better use ad-hoc mode. Ben improved log messages and added support for MSDU chaining. And, as usual, also some smaller fixes." Beyond that... Andrea Merello continues his rtl8180 refactoring, in preparation for a long-awaited rtl8187 driver. We get a new driver (rsi) for the RS9113 chip, from Fariya Fatima. And, of course, we get the usual round of updates for ath9k, brcmfmac, mwifiex, wil6210, etc. as well. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Eric W. Biederman says: ==================== Using dev_kfree/consume_skb_any for functions called in multiple contexts These changes are a result of walking through the network drivers supporting netpoll and verifying the code paths that netpoll can cause to be called in hard irq context use an appropriate flavor of kfree_skb. Either dev_kfree_skb_any or dev_consume_skb_any. Since my last pass at this I have become aware of the small differences between dev_kfree_skb_any and dev_consume_skb_any. net/core/drop_monitor.c reports the dev_kfree_skb_any as a drop and while being quite about the second. With the weird twist that dev_kfree_skb is unintuitively consume_skb. As netpoll now calls the napi poll function with budget == 0, pieces of a drivers the napi poll function that don't run when budget == 0 have been ignored. The most interesting change is to the atl1c which tried unsuccesfully to tell one of it's functions which context it is called in so that it could call dev_kfree_skb_irq or dev_kfree_skb as appropriate. I have just removed the extra parameter and called dev_consume_skb_any. At 54 separate changes I will post each change as a separate patch (so they can be reviewed) but for general sanity sake I have gathered them all into a git branch for easy acces. ==================== Acked-by: NEric Dumazet <edumazet@google.com> Signed-off-by: NDavid S.
