Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-11-03 This series contains updates to i40e and i40evf. Akeem adds a check for i40e so that flow director flush and reinit are not done when flow director is not enabled. Mitch fixes the i40evf driver to properly handle multiple admin queue messages, by reinit the msg_size field each time we go through the loop. Without this, we may receive truncated messages due to the firmware thinking we have insufficient buffer size. Also fixes the link checking logic to only check the carrier state if the interface is actually open, which allows link changes to be reported correctly without spamming the VFs. Updates i40e to inset the VSI ID in the QTX_CTL register when configuring queues for VMDq VSIs. Paul adds support for 10G-base-T in i40evf. Jesse fixes i40e where the call to irq_dynamic_disable() was turning off the interrupt completely when trying to set ITR to 0 (for lowest moderation). Shannon removes debugfs dump stats function, since it was not being kept up-to-date and was redundant with the ethtool output. Also, scales back the LAN MSIx usage to force queue/vector sharing and leave some vectors for Flow Director, VMDq, etc. when there are more cores than vectors available to the PF. Cleans up the error reporting for get_lump() resource tracking errors. Also adds a check for the debug module parameter earlier to be able to catch the early configuration phase admin queue messages. ==================== Signed-off-by: NDavid S.

Or Gerlitz says: ==================== Mellanox ethernet driver update Oct-30-2014 The 1st patch from Saeed fixes a bug in the last net-next batch where a VF could get access to set port configuration, the next patch from Amir fixes a race in the port VPI logic. Next are two performance patches from Ido. The patch to add checksum complete status on GRE and such packets was preceded with a patch that converted the driver to only use napi_gro_receive vs. the current code which goes through napi_gro_frags on it's usual track. Eric D. has some thoughts and suggestions on that change for which we want to take the time and consider, so for the time being dropped that patch and the ones that depend on it. Changes from V0: - have the caller to provide the __GFP_COLD hint to the service function - dropped the patch that changes the GRO logic and the subsequent dependent patches. ==================== Signed-off-by: NDavid S.

When IP_ALIGN has a non zero value, hardware will write to a non aligned address. The only reader from this address is when copying the header from the first frag into the linear buffer (further access to the IP address will be from the linear buffer, in which the headers are aligned). Since the penalty of non align access by the hardware is greater than the software memcpy, changing the frag_align to always be 0.

net_rx_action() can mask irqs a single time to transfert sd->poll_list into a private list, for a very short duration. Then, napi_complete() can avoid masking irqs again, and net_rx_action() only needs to mask irq again in slow path. This patch removes 2 couples of irq mask/unmask per typical NAPI run, more if multiple napi were triggered. Note this also allows to give control back to caller (do_softirq()) more often, so that other softirq handlers can be called a bit earlier, or ksoftirqd can be wakeup earlier under pressure. This was developed while testing an alternative to RX interrupt mitigation to reduce latencies while keeping or improving GRO aggregation on fast NIC. Idea is to test napi->gro_list at the end of a napi->poll() and reschedule one NAPI poll, but after servicing a full round of softirqs (timers, TX, rcu, ...). This will be allowed only if softirq is currently serviced by idle task or ksoftirqd, and resched not needed.

Pull ACPI and power management fixes from Rafael Wysocki: "These are fixes received after my previous pull request plus one that has been in the works for quite a while, but its previous version caused problems to happen, so it's been deferred till now.

Specifics: - Fix a crash on r8a7791/koelsch during resume from system suspend caused by a recent cpufreq-dt commit (Geert Uytterhoeven). - Fix an MFD enumeration problem introduced by a recent commit adding ACPI support to the MFD subsystem that exposed a weakness in the ACPI core causing ACPI enumeration to be applied to all devices associated with one ACPI companion object, although it should be used for one of them only (Mika Westerberg). - Fix an ACPI EC regression introduced during the 3.17 cycle causing some Samsung laptops to misbehave as a result of a workaround targeted at some Acer machines. That includes a revert of a commit that went too far and a quirk for the Acer machines in question.
