2013-04-29vxlan: allow choosing destination port per vxlanstephen hemminger1-5/+13
Allow configuring the default destination port on a per-device basis. Adds new netlink paramater IFLA_VXLAN_PORT to allow setting destination port when creating new vxlan. Signed-off-by: Stephen Hemminger <stephen@networkplumber.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2013-04-29vxlan: fix byte order issues with NDA_PORTstephen hemminger1-13/+15
The NDA_PORT attribute was added, but the author wasn't careful about width (port is 16 bits), or byte order. The attribute was being dumped as 16 bits, but only 32 bit value would be accepted when setting up a device. Also, the remote port is in network byte order and was being compared with default port in host byte order. Signed-off-by: Stephen Hemminger <stephen@networkplumber.org> Signed-off-by: David S.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next Jeff Kirsher says: ==================== This series contains updates to e1000e, igb and ixgbe. There are 2 patches in this series which could be applied to net, but since Linus is so very close to releasing 3.9, I do not think it prudent to try and push these into net at this time. I have CC'd stable on these patches so that they can queue them up as soon as 3.9 gets released. The 2 patches are: e1000e: fix numeric overflow in phc settime method ixgbe: fix EICR write in ixgbe_msix_other Richard provides a fix for e1000e by using a helper function from time.h to resolve a unintended overflow in the PTP settime function. Bruce provides a fix to wait for NAPI to be done with the current context after disabling interrupts and then disable NAPI when the interface is going down. This fixes a possible "unable to handle kernel paging request" panic in net-next. Andi Kleen provides a patch for igb to use mdelay instead of udelay when we needed 100000us. Jacob provides a fix for ixgbe to simply mask the lower 16bits off so that ixgbe_msix_other does not write them in the EICR, which causes them to remain high and be properly handled by the clean_rings interrupt routine as normal. Emil cleans up the logic in ixgbe_setup_loopback_test() to only access registers applicable to the MAC type. In addition, removes majority of the AUTOC register reads by using a cached value instead to avoid writing corrupted values to AUTOC due to bad FW. Emil also add support for disabling link during boot time. Lastly, he provides a patch which adds the MAC type to the version in ethtool_regs which will make it easier to check the MAC type when dumping registers with ethtool. There is a separate ethtool tool patch which is dependent upon Emil's last patch of the series to add the MAC type to the version in ethtool_regs, which will be sent separately. ==================== Signed-off-by: David S.

2013-04-25ixgbe: fix EICR write in ixgbe_msix_otherJacob Keller1-0/+10
Previously, the ixgbe_msix_other was writing the full 32bits of the set interrupts, instead of only the ones which the ixgbe_msix_other is handling. This resulted in a loss of performance when the X540's PPS feature is enabled due to sometimes clearing queue interrupts which resulted in the driver not getting the interrupt for cleaning the q_vector rings often enough. The fix is to simply mask the lower 16bits off so that this handler does not write them in the EICR, which causes them to remain high and be properly handled by the clean_rings interrupt routine as normal.

2013-04-25net/cpsw: fix irq_disable() with threaded interruptsSebastian Siewior1-3/+22
During high throughput it is likely that we receive both: an RX and TX interrupt. The normal behaviour is that once we enter the ISR the interrupts are disabled in the IRQ chip and so the ISR is invoked only once and the interrupt line is disabled once. It will be re-enabled after napi completes. With threaded interrupts on the other hand the interrupt the interrupt is disabled immediately and the ISR is marked for "later". By having TX and RX interrupt marked pending we invoke them both and disable the interrupt line twice. The napi callback is still executed once and so after it completes we remain with interrupts disabled. The initial patch simply removed the cpsw_{enable|disable}_irq() calls and it worked well on my AM335X ES1.0 (beagle bone). On ES2.0 (beagle bone black) it caused an never ending interrupt (even after the mask via cpsw_intr_disable()) according to Mugunthan V N. Since I don't have the ES2.0 and no idea what is going on this patch tracks the state of the irq_disable() call and execute it only when not yet done. The book keeping is done on the first struct since with dual_emac we can have two of those and only one interrupt line.

2013-04-25net/cpsw: redo rx skb allocation in rx pathSebastian Siewior2-21/+19
In case that we run into OOM during the allocation of the new rx-skb we don't get one and we have one skb less than we used to have. If this continues to happen then we end up with no rx-skbs at all. This patch changes the following: - if we fail to allocate the new skb, then we treat the currently completed skb as the new one and so drop the currently received data. - instead of testing multiple times if the device is gone we rely one the status field which is set to -ENOSYS in case the channel is going down and incomplete requests are purged. cpdma_chan_stop() removes most of the packages with -ENOSYS. The currently active packet which is removed has the "tear down" bit set. So if that bit is set, we send ENOSYS as well otherwise we pass the status bits which are required to figure out which of the two possible just finished.

2013-04-25net/cpsw: don't rely only on netif_running() to check which device is activeSebastian Siewior1-11/+22
netif_running() reports false before the ->ndo_stop() callback is called. That means if one executes "ifconfig down" and the system receives an interrupt before the interrupt source has been disabled we hang for always for two reasons: - we never disable the interrupt source because devices claim to be already inactive and don't feel responsible. - since the ISR always reports IRQ_HANDLED the line is never deactivated because it looks like the ISR feels responsible. This patch changes the logic in the ISR a little: - If none of the status registers reports an active source (RX or TX, misc is ignored because it is not actived) we leave with IRQ_NONE. - the interrupt is deactivated - The first active network device is taken and napi is scheduled. If none are active (a small race window between ndo_down() and the interrupt the) then we leave and should not come back because the source is off. There is no need to schedule the second NAPI because both share the same dma queue.

In worst case we have zero RX skbs and can't ever receive further packets since the RX skbs are never reallocated. If cpdma_chan_submit() fails we even leak the skb. This patch changes the behavior here: If we fail to allocate an skb during bring up we don't continue and report that error. Same goes for errors from cpdma_chan_submit(). While here I changed to __netdev_alloc_skb_ip_align() so GFP_KERNEL can be used.

2013-04-24pci: Add SRIOV helper function to determine if VFs are assigned to guestAlexander Duyck1-0/+41
This function is meant to add a helper function that will determine if a PF has any VFs that are currently assigned to a guest. We currently have been implementing this function per driver, and going forward I would like to avoid that by making this function generic and using this helper. v2: Removed extern from declaration of pci_vfs_assigned in pci.h and return 0 if SR-IOV is disabled with is inline with other PCI SRIOV functions.

2013-04-24igb: Add SMBI semaphore to I210/I211Matthew Vick3-26/+43
It was previously thought that, since I210/I211 are single port devices, they did not need the SMBI semaphore. This is not the case. Add support for the SMBI semaphore.

2013-04-24igb: SERDES loopback sigdetect bit on i210 devicesAkeem G. Abodunrin1-7/+2
This patch implements SERDES loopback configuration for i210 devices by unsetting sigdetect bit, so as to fix Ethtool loopback test failure. Old sigdetect code is also simplified to take care of all devices newer than 82580 Signed-off-by: Akeem G Abodunrin <akeem.g.abodunrin@intel.com> Tested-by: Aaron Brown <aaron.f.brown@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>

2013-04-24ixgbe: add SFP+ LX module supportDon Skidmore4-10/+25
This patch adds LX support to 82599 devices. This is an alternate patch to the one suggested by Stefan Behte <s.behte@babiel.com> In addition this patch includes some cleanups such as: - removed parenthesis around "x == y ||" lines inside an if statement for consistency. - grouped the sx/lx sfp types along with srlr in ixgbe_get_settings() since they all have the same supported, advertised and port values.
