The definition of I217_PROXY_CTRL must use the BM_PHY_REG() macro instead of the PHY_REG() macro for PHY page 800 register 70 since it is for a PHY register greater than the maximum allowed by the latter macro, and fix a typo setting the I217_MEMPWR register in e1000_suspend_workarounds_ich8lan. Also for clarity, rename a few defines as bit definitions instead of masks. Signed-off-by:

While testing how linux behaves on SYNFLOOD attack on multiqueue device (ixgbe), I found that SYNACK messages were dropped at Qdisc level because we send them all on a single queue. Obvious choice is to reflect incoming SYN packet @queue_mapping to SYNACK packet. Under stress, my machine could only send 25.000 SYNACK per second (for 200.000 incoming SYN per second). NIC : ixgbe with 16 rx/tx queues. After patch, not a single SYNACK is dropped. Signed-off-by:

Currently, we terminate the eeprom access through clearing the CS by: RTL_W8 (Cfg9346, ~EE_CS); or writeb (~EE_CS, ee_addr); This would left the eeprom into "Config. Register Write Enable:" state which is not expcted as the highest two bits were set to 0x11 ( expected is the "Normal" mode (0x00)). Solving this by write 0x0 instead of ~EE_CS when terminating the eeprom access. Signed-off-by:

When NetLabel is not enabled, e.g. CONFIG_NETLABEL=n, and the system receives a CIPSO tagged packet it is dropped (cipso_v4_validate() returns non-zero). In most cases this is the correct and desired behavior, however, in the case where we are simply forwarding the traffic, e.g. acting as a network bridge, this becomes a problem. This patch fixes the forwarding problem by providing the basic CIPSO validation code directly in ip_options_compile() without the need for the NetLabel or CIPSO code. The new validation code can not perform any of the CIPSO option label/value verification that cipso_v4_validate() does, but it can verify the basic CIPSO option format. The behavior when NetLabel is enabled is unchanged. Signed-off-by:

Port is used as an array index before we know if that is proper. For example, in the catas event case, port is zero; however, the port index should lie in the range (1..2). Fix this by using 'port' only in the events where it is of interest. Test for port out of range in the default (unhandled event) case, and do not output a message if it is not an ethernet port.

In SRIOV mode, the number of EQs used when computing the total ICM size was incorrect. To fix this, we do the following: 1. We add a new structure to mlx4_dev, mlx4_phys_caps, to contain physical HCA capabilities. The PPF uses the phys capabilities when it computes things like ICM size. The dev_caps structure will then contain the paravirtualized values, making bookkeeping much easier in SRIOV mode. We add a structure rather than a single parameter because there will be other fields in the phys_caps. The first field we add to the mlx4_phys_caps structure is num_phys_eqs. 2. In INIT_HCA, when running in SRIOV mode, the "log_num_eqs" parameter passed to the FW is the number of EQs per VF/PF; each function (PF or VF) has this number of EQs available. However, the total number of EQs which must be allowed for in the ICM is (1 << log_num_eqs) * (#VFs + #PFs). Rather than compute this quantity, we allocate ICM space for 1024 EQs (which is the device maximum number of EQs, and which is the value we place in the mlx4_phys_caps structure). For INIT_HCA, however, we use the per-function number of EQs as described above. Signed-off-by:

Pull Sparc updates from David S. Miller: 1) Remove the idiotic situation wherein Leon was a special case in all of the TLB/cache handling code. The worst side effect of this bogosity is that you couldn't build a kernel with Leon support enabled (to get better build coverage), and test boot it on a non-LEON cpu. Leon is, in all core respects, programatically identical to the 32-bit SRMMU. Except that they put the TLB registers in a different alternate address space location. Through code patching (for fast paths) and run time checks, this issue is now a thing of the past. From Sam Ravnborg. 2) There was a mis-merge of arch/sparc/Kconfig for one of the clockevents changes that went in, causing 32-bit sparc to start failing to build. I merged in your tree to get those clockevents changes (and added a note to the merge commit) then added Stephen Rothwell's fix for the merge error. 3) Software quad floating point emulation was not working properly on more recent Niagara chips, because the way the situation is reported by the cpu has changed.

'cmd_issue_lock' is for only acquiring a free slot, and it is not used in interrupt context. So replaced irq version with non-irq version of spinlock. Signed-off-by:
