2014-03-31ixgbe: fix race conditions on queuing skb for HW time stampJakub Kicinski
ixgbe has a single set of TX time stamping resources per NIC. Use a simple bit lock to avoid race conditions and leaking skbs when multiple TX rings try to claim time stamping.

2014-03-31ixgbe: never generate both software and hardware timestampsJakub Kicinski
skb_tx_timestamp() does not report software time stamp if SKBTX_IN_PROGRESS is set. According to timestamping.txt software time stamps are a fallback and should not be generated if hardware time stamp is provided. Move call to skb_tx_timestamp() after setting SKBTX_IN_PROGRESS.

2014-03-31e1000e: Fix no connectivity when driver loaded with cable outDavid Ertman
In commit da1e2046e5, the flow for enabling/disabling an Si errata workaround (e1000_lv_jumbo_workaround_ich8lan) was changed to fix a problem with iAMT connections dropping on interface down with jumbo frames set. Part of this change was to move the function call disabling the workaround to e1000e_down() from the e1000_setup_rctl() function. The mechanic for disabling of this workaround involves writing several MAC and PHY registers back to hardware defaults. After this commit, when the driver is loaded with the cable out, the PHY registers are not programmed with the correct default values. This causes the device to be capable of transmitting packets, but is unable to recieve them until this workaround is called. The flow of e1000e's open code relies upon calling the above workaround to expicitly program these registers either with jumbo frame appropriate settings or h/w defaults on 82579 and newer hardware. Fix this issue by adding logic to e1000_setup_rctl() that not only calls e1000_lv_jumbo_workaround_ich8lan() when jumbo frames are set, to enable the workaround, but also calls this function to explicitly disable the workaround in the case that jumbo frames are not set.

2014-03-31rtl8180: don't use weird trick to access "far" registersAndrea Merello
In rtl8180/rtl8185/rtl8187se the register space is represented using packed structure type. Register are thus accessed using a pointer of this type. All registers are packed toghether, and only small gaps are present. However Rtl8187se has also some "sparse" registers, very far from the "main register block". It could be possible to access them by simply declare huge reserved blocks inside the register struct (and this causes NO memory waste). However, for various reasons, access to those "far" registers is done with special dedicated macros, without declaring them in the register struct. This is done in an intricate manner, that makes code less readable and caused static analisys tool to produce warnings. This patch keeps the "macro" mechanism, but it changes its implementation in a simplier and more straightforward way. Signed-off-by: Andrea Merello <andrea.merello@gmail.com> Signed-off-by: John W.

There are currently pch_gbe, cpts, and ixp4xx_eth drivers that open-code and reimplement a BPF classifier for the PTP protocol. Since all of them effectively do the very same thing and load the very same PTP/BPF filter, we can just consolidate that code by introducing ptp_classify_raw() in the time-stamping core framework which can be used in drivers. As drivers get initialized after bootstrapping the core networking subsystem, they can make use of ptp_insns wrapped through ptp_classify_raw(), which allows to simplify and remove PTP classifier setup code in drivers.

2014-03-29xen-netback: worse-case estimate in xenvif_rx_action is underestimatingPaul Durrant
The worse-case estimate for skb ring slot usage in xenvif_rx_action() fails to take fragment page_offset into account. The page_offset does, however, affect the number of times the fragmentation code calls start_new_rx_buffer() (i.e. consume another slot) and the worse-case should assume that will always return true. This patch adds the page_offset into the DIV_ROUND_UP for each frag. Unfortunately some frontends aggressively limit the number of requests they post into the shared ring so to avoid an estimate that is 'too' pessimal it is capped at MAX_SKB_FRAGS.

2014-03-29net: mvneta: use devm_ioremap_resource() instead of of_iomap()Thomas Petazzoni
The mvneta driver currently uses of_iomap(), which has two drawbacks: it doesn't request the resource, and it isn't devm-style so some error handling is needed. This commit switches to use devm_ioremap_resource() instead, which automatically requests the resource (so the I/O registers region shows up properly in /proc/iomem), and also is devm-style, which allows to get rid of some error handling to unmap the I/O registers region.

qlge driver turns off NETIF_F_HW_CTAG_FILTER, but forgets to turn off HW_CTAG_TX and HW_CTAG_RX on vlan devices. With the current settings, q-in-q will only generate a single vlan header. Remember to mask off CTAG_TX and CTAG_RX features in vlan_features.

2014-03-28sh_eth: ensure pm_runtime cannot suspend the device during initBen Dooks
The pm_rumtime work queue is causing the device to be suspended during initialisation, thus the initialisation may not be able to access registers properly. As the code is called from a work queue, it is possible that this is not seen from certain configurations/builds due to the asynchronos nature of the code. Another issue has also been found where the network device registration calls back into the driver thus causing further pm_runtime calls that also caused issues with the MDIO bus code. This has now been checked and is the only place the MDIO can be called without the device open. Use pm_runtime_get_sync() and pm_runtime_put() to ensure that the pm system does not suspend it during the probe() call and remove the now unnecessary pm_runtime_resume() call. Also add a call in the error path to call pm_runtime_disable(). This fixes the external abort that can cause /sbin/init or other such init processed to die.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series contains updates to e1000e, igb, i40e and i40evf Anjali provides i40e fix to remove the ATR filter on RST as well as FIN packets. Cleans up add_del_fdir() because it was used and implemented only for the add, so change the name and drop a parameter. Adds the ability to drop a flow if we wanted to and adds a flow director message level to be used for flow director specific messages. Mitch fixes an issue on i40evf where the Tx watchdog handler was causing an oops when sending an admin queue message to request a reset because the admin queue functions use spinlocks. Greg provides a change to i40e to make the alloc and free queue vector calls orthogonal. Shannon fixes i40e to verify the eeprom checksum and firmware CRC status bits, and shutdown the driver if they fail. This change stops the processing of traffic, but does not kill the PF netdev so that the NVMUpdate process still has a chance at fixing the image. Also provides a fix to make sure the VSI has a netdev before trying to use it in the debugfs netdev_ops commands. Jakub Kicinski provides patches for e1000e and igb to fix a number issues found in the PTP code. v2: - drop patch 11 "i40e: Add a fallback debug flow for the driver" from the series based on feedback from David Miller ==================== Signed-off-by: David S.
