2014-10-06fec: Fix fec_enet_alloc_buffers() error pathFabio Estevam1-7/+10
When fec_enet_alloc_buffers() fails we should better undo the previous actions, which consists of: disabling the FEC clocks and putting the FEC pins into inactive state. The error path for fec_enet_mii_probe() is kept unchanged. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2014-10-05Altera TSE: Add support for no PHYWalter Lozano1-0/+8
This patch avoids PHY and MDIO probing if no PHY chip is present. This is the case mainly in optical links where there is no need for PHY chip, and therefore no need of MDIO.

Linville says: ==================== pull request: wireless-next 2014-10-03 Please pull tihs batch of updates intended for the 3.18 stream! For the iwlwifi bits, Emmanuel says: "I have here a few things that depend on the latest mac80211's changes: RRM, TPC, Quiet Period etc... Eyal keeps improving our rate control and we have a new device ID. This last patch should probably have gone to wireless.git, but at that stage, I preferred to send it to -next and CC stable." For (most of) the Atheros bits, Kalle says: "The only new feature is testmode support from me. Ben added a new method to crash the firmware with an assert for debug purposes. As usual, we have lots of smaller fixes from Michal. Matteo fixed a Kconfig dependency with debugfs. I fixed some warnings recently added to checkpatch." For the NFC bits, Samuel says: "We've had major updates for TI and ST Microelectronics drivers, and a few NCI related changes. For TI's trf7970a driver: - Target mode support for trf7970a - Suspend/resume support for trf7970a - DT properties additions to handle different quirks - A bunch of fixes for smartphone IOP related issues For ST Microelectronics' ST21NFCA and ST21NFCB drivers: - ISO15693 support for st21nfcb - checkpatch and sparse related warning fixes - Code cleanups and a few minor fixes Finally, Marvell added ISO15693 support to the NCI stack, together with a couple of NCI fixes." For the Bluetooth bits, Johan says: "This 3.18 pull request replaces the one I did on Monday ("bluetooth-next 2014-09-22", which hasn't been pulled yet). The additions since the last request are: - SCO connection fix for devices not supporting eSCO - Cleanups regarding the SCO establishment logic - Remove unnecessary return value from logging functions - Header compression fix for 6lowpan - Cleanups to the ieee802154/mrf24j40 driver Here's a copy from previous request that this one replaces: ' Here are some more patches for 3.18. They include various fixes to the btusb HCI driver, a fix for LE SMP, as well as adding Jukka to the MAINTAINERS file for generic 6LoWPAN (as requested by Alexander Aring). I've held on to this pull request a bit since we were waiting for a SCO related fix to get sorted out first. However, since the merge window is getting closer I decided not to wait for it. If we do get the fix sorted out there'll probably be a second small pull request later this week. '" And, "Unless 3.17 gets delayed this will probably be our last -next pull request for 3.18. We've got: - New Marvell hardware supportr - Multicast support for 6lowpan - Several of 6lowpan fixes & cleanups - Fix for a (false-positive) lockdep warning in L2CAP - Minor btusb cleanup" On top of all that comes the usual sort of updates to ath5k, ath9k, ath10k, brcmfmac, mwifiex, and wil6210. This time around there are also a number of rtlwifi updates to enable some new hardware and to reconcile the in-kernel drivers with some newer releases of the Realtek vendor drivers. Also of note is some device tree work for the bcma bus. Please let me know if there are problems! ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-10-02 This series contains updates to fm10k, igb, ixgbe and i40e. Alex provides two updates to the fm10k driver. First reduces the buffer size to 2k for all page sizes, since most frames only have a 1500 MTU so supporting a buffer size larger than this is somewhat wasteful. Second fixes an issue where the number of transmit queues was not being updated, so added the lines necessary to update the number of transmit queues. Rick Jones provides two patches to convert ixgbe, igb and i40e to use dev_consume_skb_any(). Emil provides two patches for ixgbe, first cleans up a couple of wait loops on auto-negotiation that were not needed. Second fixes an issue reported by Fujitsu/Red Hat, which consolidates the logic behind the dynamically setting of TXDCTL.WTHRESH depending on interrupt throttle rate (ITR) setting regardless of BQL. Ethan Zhao provides a cleanup patch for ixgbe where he noticed a duplicate define. Bernhard Kaindl provides a patch for igb to remove a source of latency spikes by not calling code that uses mdelay() for feeding a PHY stat while being called with a spinlock held. Todd bumps the igb version based on the recent changes. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2014-10-02ath9k: Fix queue handling for channel contextsSujith Manoharan1-6/+1
When a full chip reset is done, all the queues across all VIFs are stopped, but if MCC is enabled, only the queues of the current context is awakened, when we complete the reset. This results in unfairness for the inactive context. Since frames are queued internally in the driver if there is a context mismatch, we can awaken all the queues when coming out of a reset. The VIF-specific queues are still used in flow control, to ensure fairness when traffic is high. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W.

2014-10-02igb: remove blocking phy read from inside spinlockBernhard Kaindl3-18/+0
Remove a source of latency spikes (in my case up to 10ms) by not calling code that uses mdelay() for feeding a phy statistic (rx errors for idle symbols - not data -> idle_errors) while being called with a spinlock held. As idle_errors isn't read, this patch only removes unused code and data. Later, more complicated changes may be applied to address the spinlock and allow for some PHY diagnostics by harvesting this PHY stats register fully. This patch is designed to fix the issue and be safe for longterm/stable. For the Intel e1000e driver, the same change was applied in 2008 with commit 23033fad5be0 ("e1000e: remove phy read from inside spinlock"). The mdelay is triggered by HW/SW semaphores, thus it depends on the HW. I've HW that triggers it even when idle. Others may trigger it only e.g. when Ethernet ports aquire or loose the link or on ifconfig up / down. We've noticed this first from delays in frame rx/tx due to the mdelay(). Example command for checking if the issue is triggered: cyclictest -Smp1 (Look for occasional "Max:" values > 4000 or use -b 4000 to stop if greater) It was observed with I350 ports connected to other I350 ports, but not if driver and EEPROM was modified to run the I350 in EEPROM-less mode. phy_stats.idle_errors and .receive_errors (isn't touched) occupy 64 not used bits in the adapter struct: Their allocation may be removed as well.

2014-10-02ixgbe: fix setting of TXDCTL.WTRHESH when ITR is set to 0 and no BQLEmil Tantilov2-6/+1
This patch consolidates the logic behind dynamically setting TXDCTL.WTHRESH depending on interrupt throttle rate (ITR) setting regardless of BQL. Previously TXDCTL.WTHRESH was dynamically being set only with BQL being enabled, but we have to set it regardless of BQL when ITR is low to avoid Tx stalls/hangs.

2014-10-02ixgbe: remove wait loop on autoneg for copper devicesEmil Tantilov1-41/+0
This patch removes couple of wait loops on autoneg that are not needed. During validation we noticed that the loops always time out, so there should be no user impact.

2014-10-02ixgbe: Convert the normal transmit complete path to dev_consume_skb_any()Rick Jones1-1/+1
Convert the normal packet completion path to dev_consume_skb_any() so packet drop profiling via dropwatch or perf top -G -e skb_kfree_skb is not cluttered with false hits. Compile tested only. There is a dev_kfree_skb_any() in the routine ixgbe_ptp_tx_hwtstamp() in ixgbe_ptp.c that looks like a conversion candidate but I wasn't familiar enough with the code to pull the trigger.
