Pull networking fixes from David Miller: "Bug fixes galore, mostly in drivers as is often the case: 1) USB gadget and cdc_eem drivers need adjustments to their frame size lengths in order to handle VLANs correctly. From Ian Coolidge. 2) TIPC and several network drivers erroneously call tasklet_disable before tasklet_kill, fix from Xiaotian Feng. 3) r8169 driver needs to apply the WOL suspend quirk to more chipsets, fix from Cyril Brulebois. 4) Fix multicast filters on RTL_GIGA_MAC_VER_35 r8169 chips, from Nathan Walp. 5) FDB netlink dumps should use RTM_NEWNEIGH as the message type, not zero. From John Fastabend. 6) Fix smsc95xx tx checksum offload on big-endian, from Steve Glendinning. 7) __inet_diag_dump() needs to repsect and report the error value returned from inet_diag_lock_handler() rather than ignore it. Otherwise if an inet diag handler is not available for a particular protocol, we essentially report success instead of giving an error indication. Fix from Cyrill Gorcunov. 8) When the QFQ packet scheduler sees TSO/GSO packets it does not handle things properly, and in fact ends up corrupting it's datastructures as well as mis-schedule packets. Fix from Paolo Valente. 9) Fix oopser in skb_loop_sk(), from Eric Leblond. 10) CXGB4 passes partially uninitialized datastructures in to FW commands, fix from Vipul Pandya. 11) When we send unsolicited ipv6 neighbour advertisements, we should send them to the link-local allnodes multicast address, as per RFC4861. Fix from Hannes Frederic Sowa. 12) There is some kind of bug in the usbnet's kevent deferral mechanism, but more immediately when it triggers an uncontrolled stream of kernel messages spam the log. Rate limit the error log message triggered when this problem occurs, as sending thousands of error messages into the kernel log doesn't help matters at all, and in fact makes further diagnosis more difficult. From Steve Glendinning. 13) Fix gianfar restore from hibernation, from Wang Dongsheng. 14) The netlink message attribute sizes are wrong in the ipv6 GRE driver, it was using the size of ipv4 addresses instead of ipv6 ones :-) Fix from Nicolas Dichtel." * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: gre6: fix rtnl dump messages gianfar: ethernet vanishes after restoring from hibernation usbnet: ratelimit kevent may have been dropped warnings ipv6: send unsolicited neighbour advertisements to all-nodes net: usb: cdc_eem: Fix rx skb allocation for 802.1Q VLANs usb: gadget: g_ether: fix frame size check for 802.1Q cxgb4: Fix initialization of SGE_CONTROL register isdn: Make CONFIG_ISDN depend on CONFIG_NETDEVICES cxgb4: Initialize data structures before using. af-packet: fix oops when socket is not present pkt_sched: enable QFQ to support TSO/GSO net: inet_diag -- Return error code if protocol handler is missed net: bnx2x: Fix typo in bnx2x driver smsc95xx: fix tx checksum offload for big endian rtnetlink: Use nlmsg type RTM_NEWNEIGH from dflt fdb dump ptp: update adjfreq callback description r8169: allow multicast packets on sub-8168f chipset. r8169: Fix WoL on RTL8168d/8111d. drivers/net: use tasklet_kill in device remove/close process tipc: do not use tasklet_disable before tasklet_kill

2012-11-09sparc: Add sparc support for platform_get_irq()Andreas Larsson
This adds sparc support for platform_get_irq that in the normal case use platform_get_resource() to get an irq. This standard approach fails for sparc as there are no resources of type IORESOURCE_IRQ for irqs for sparc. Cross platform drivers can then use this standard platform function and work on sparc instead of having to have a special case for sparc.

2012-11-09gianfar: ethernet vanishes after restoring from hibernationWang Dongsheng
If a gianfar ethernet device is down prior to hibernating a system, it will no longer be present upon system restore. For example: ~# ifconfig eth0 down ~# echo disk > /sys/power/state <trigger a restore from hibernation> ~# ifconfig eth0 up SIOCSIFFLAGS: No such device This happens because the restore function bails out early upon finding devices that were not up at hibernation. In doing so, it never gets to the netif_device_attach call at the end of the restore function. Adding the netif_device_attach as done here also makes the gfar_restore code consistent with what is done in the gfar_resume code.

2012-11-09usbnet: ratelimit kevent may have been dropped warningsSteve Glendinning
when something goes wrong, a flood of these messages can be generated by usbnet (thousands per second). This doesn't generally *help* the condition so this patch ratelimits the rate of their generation. There's an underlying problem in usbnet's kevent deferral mechanism which needs fixing, specifically that events *can* get dropped and not handled. This patch doesn't address this, but just mitigates fallout caused by the current implemention. Signed-off-by: Steve Glendinning <steve.glendinning@shawell.net> Signed-off-by: David S.

2012-11-09virtio: Don't access index after unregister.Cornelia Huck
Virtio wants to release used indices after the corresponding virtio device has been unregistered. However, virtio does not hold an extra reference, giving up its last reference with device_unregister(), making accessing dev->index afterwards invalid. I actually saw problems when testing my (not-yet-merged) virtio-ccw code: - device_add virtio-net,id=xxx -> creates device virtio<n> with n>0 - device_del xxx -> deletes virtio<n>, but calls ida_simple_remove with an index of 0 - device_add virtio-net,id=xxx -> tries to add virtio0, which is still in use... So let's save the index we want to release before calling device_unregister().

There are two problems here: The check for vmmc was printing an unnecessary pr_info() when host->vmmc is NULL.

2012-11-07mmc: dw_mmc: fix multiple drv_data NULL dereferencesJames Hogan
800d78bfccb3d ("mmc: dw_mmc: add support for implementation specific callbacks") -- merged in v3.7-rc1 -- introduced multiple NULL pointer dereferences when the default dw_mci_pltfm_probe() is used, as it sets host->drv_data to NULL, and that's only checked against NULL in 1 out of the 7 cases where it is dereferenced.

2012-11-07mmc: dw_mmc: enable controller interrupt before calling mmc_start_hostYuvaraj CD
As mmc_start_host is getting called before enabling the dw_mmc controller interrupt, there is a problem of missing the SDMMC_INT_CMD_DONE for the very first command sent by the sdio_reset. This problem occurs only when we disable MMC debugging i.e, MMC_DEBUG=n. This patch enables the dw_mmc controller interrupt before mmc_start_host.

2012-11-07mmc: sdhci-of-esdhc: disable CMD23 for some Freescale SoCsJerry Huang
CMD23 causes lots of errors in kernel on some freescale SoCs (P1020, P1021, P1022, P1024, P1025 and P4080) when MMC card used, which is because these controllers does not support CMD23, even on the SoCs which declares CMD23 is supported. Therefore, we'll not use CMD23.
