2014-06-13vxlan: use dev->needed_headroom instead of dev->hard_header_lenCong Wang
When we mirror packets from a vxlan tunnel to other device, the mirror device should see the same packets (that is, without outer header). Because vxlan tunnel sets dev->hard_header_len, tcf_mirred() resets mac header back to outer mac, the mirror device actually sees packets with outer headers Vxlan tunnel should set dev->needed_headroom instead of dev->hard_header_len, like what other ip tunnels do. This fixes the above problem. Cc: "David S.

2014-06-12bnx2x: Enlarge the dorq threshold for VFsAriel Elior
A malicious VF might try to starve the other VFs & PF by creating contineous doorbell floods. In order to negate this, HW has a threshold of doorbells per client, which will stop the client doorbells from arriving if crossed. The threshold currently configured for VFs is too low - under extreme traffic scenarios, it's possible for a VF to reach the threshold and thus for its fastpath to stop working.

2014-06-11sfc: PIO:Restrict to 64bit arch and use 64-bit writes.Jon Cooper
Fixes:ee45fd92c739 ("sfc: Use TX PIO for sufficiently small packets") The linux net driver uses memcpy_toio() in order to copy into the PIO buffers. Even on a 64bit machine this causes 32bit accesses to a write- combined memory region. There are hardware limitations that mean that only 64bit naturally aligned accesses are safe in all cases. Due to being write-combined memory region two 32bit accesses may be coalesced to form a 64bit non 64bit aligned access. Solution was to open-code the memory copy routines using pointers and to only enable PIO for x86_64 machines. Not tested on platforms other than x86_64 because this patch disables the PIO feature on other platforms. Compile-tested on x86 to ensure that works. The WARN_ON_ONCE() code in the previous version of this patch has been moved into the internal sfc debug driver as the assertion was unnecessary in the upstream kernel code.

This patch fixes an issue that we cannot use nfs rootfs correctly on r8a7790 when the command below runs on a host PC. $ sudo ping -f -l 8 $BOARD_IP_ADDR Since the driver sets the RACT to 1 in the first while loop of sh_eth_rx(), the controller accepts a next frame into the next RX descriptor during the while loop.

The “affinity hint” mechanism is used by the user space daemon, irqbalancer, to indicate a preferred CPU mask for irqs. Irqbalancer can use this hint to balance the irqs between the cpus indicated by the mask. We wish the HCA to preferentially map the IRQs it uses to numa cores close to it. To accomplish this, we use cpumask_set_cpu_local_first(), that sets the affinity hint according the following policy: First it maps IRQs to “close” numa cores.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-06-11 This series contains updates to igb, i40e and i40evf. Todd makes a change to igb to un-hide invariant returns by getting rid of the E1000_SUCCESS define and converting those returns to return 0. Jacob separates the hardware logic from the set function, so that we can re-use it during a ptp_reset in igb. This enables the reset to return functionality to the last know timestamp mode, rather than resetting the value. Ashish implements context flags for headwb and headwb_addr so that we do not have to keep them always enabled. Shannon updates the admin queue API for the new firmware, which adds set_pf_content, nvm_config_read/write, replaces set_phy_reset with set_phy_debug and removes nvm_read/write_reg_se. Cleans up the driver to use the stored base_queue value since there is no need to read the PCI register for the PF's base queue on every single transmit queue enable and disable as we already have the value stored from reading the capability features at startup. Anjali changes the notion of source and destination for FD_SB in ethtool to align i40e with other drivers. Adds flow director statistics to the PF stats. Fixes a bug in ethtool for flow director drop packet filter where the drop action comes down as a ring_cookie value, so allow it as a special value that can be used to configure destination control. Mitch fixes the i40evf to keep the driver from going down when it is already in a down state. This prevents a CPU soft lock in napi_disable(). Also change the i40evf to check the admin queue error bits since the firmware can indicate any admin queue error states to the driver via some bits in the length registers. Neerav separates out the DCB capability and enabled flags because currently if the firmware reports DCB capability the driver enables I40E_FLAG_DCB_ENABLED flag. When this flag is enabled the driver inserts a tag when transmitting a packet from the port even if there are no DCB traffic classes configured at the port. So by adding the additional flag, I40E_FLAG_DCB_CAPABLE, that will be set when the DCB capability is present and the existing enabled flag will only be set if there are more than one traffic classes configured at the port. Greg fixes the i40e driver to not automatically accept tagged packets by default so that the system must request a VLAN tag packet filter to get packets with that tag. Greg also converts i40e to use the in-kernel ether_addr_copy() instead of mempcy(). Jesse removes the FTYPE field from the receive descriptor to match the hardware implementation. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2014-06-11i40e/i40evf: set headwb Tx context flags and use themAshish Shah
Set appropriate fields in Tx queue configuration virtchnl message to pf to enable headwb and setup headwb addr. Then use that info from the VF to set headwb and headwb_addr instead of always enabling them.

2014-06-11igb: separate hardware setting from the set_ts_config ioctlJacob Keller
This patch separates the hardware logic from the set function, so that we can re-use it during a ptp_reset. This enables the reset to return functionality to the last known timestamp mode, rather than resetting the value. We initialize the mode to off during the ptp_init cycle.

2014-06-11amd-xgbe: Rename MAX_DMA_CHANNELS to avoid powerpc conflictLendacky, Thomas
MAX_DMA_CHANNELS is defined in asm/scatterlist.h of the powerpc architecture. Rename this #define in xgbe.h to avoid the redefined warning issued during compilation.

2014-06-11farsync: Fix confusion about DMA address and buffer offset typesBen Hutchings
Use dma_addr_t for DMA address parameters and u32 for shared memory offset parameters. Do not assume that dma_addr_t is the same as unsigned long; it will not be in PAE configurations. Truncate DMA addresses to 32 bits when printing them. This is OK because the DMA mask for this device is 32-bit (per default). Also rename the DMA address parameters from 'skb' to 'dma'. Compile-tested only. Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Signed-off-by: David S. Miller <davem@davemloft.net>
