Under "heavy" RX load, the driver cannot handle the descriptors fast
enough. In detail, when a descriptor is consumed, its used flag is
cleared and once the RX budget is consumed all descriptors with a
cleared used flag are prepared to receive more data. Under load though,
the HW may constantly receive more data and use those descriptors with a
cleared used flag before they are actually prepared for next usage.

The head and tail pointers into the RX-ring should always be valid and
we can omit clearing and checking of the used flag.

In ip_tunnel_rcv(), set skb->network_header to inner IP header
before IP_ECN_decapsulate().

Without the fix, IP_ECN_decapsulate() takes outer IP header as
inner IP header, possibly causing error messages or packet drops.

Note that this skb_reset_network_header() call was in this spot when
the original feature for checking consistency of ECN bits through
tunnels was added in eccc1bb8 ("tunnel: drop packet if ECN present
with not-ECT"). It was only removed from this spot in 3d7b46cd
("ip_tunnel: push generic protocol handling to ip_tunnel module.").

Intel Wired LAN Driver Updates

This series contains updates to e1000e only.

David provides four fixes for e1000e, first is a workaround for a hardware
erratum on 82579 devices which experienced packet loss in gigabit and 100
speeds when interconnect between the PHY and MAC is exiting K1 power saving
state.  Second expands the scope of a workaround to include i217 and i218
parts as well to address over aggressive transmit behavior when connecting
at 10Mbs half-duplex.  Next is to resolve a reported link flap issue on
82579 parts which was root caused as an interoperability problem between
82579 and at least some Broadcom PHYs in the Energy Efficient Ethernet wake
mechanism.  Lastly, restricts the workaround of putting the PHY into MDIO
slow mode to access the PHY id to relevant parts since this issue has been
fixed on the newer hardware.

It has been determined that the workaround of putting the PHY into MDIO
slow mode to access the PHY id is not necessary with Lynx Point and newer
parts.  The issue that necessitated the workaround has been fixed on the
newer hardware.

We will maintains, as a last ditch attempt, the conversion to MDIO Slow
Mode in the failure branch when attempting to access the PHY id so as to
cover all contingencies.

Several customers have reported a link flap issue on 82579. The symptoms
are random and intermittent link losses when 82579 is connected to specific
link partners. Issue has been root caused as interoperability problem
between 82579 and at least some Broadcom PHYs in the Energy Efficient
Ethernet wake mechanism.

To fix the issue, we are disabling the Phase Locked Loop shutdown in 100M
Low Power Idle.  This solution will cause an increase of power in 100M EEE
link. It will cost additional 28mW in this specific mode.

to address the overaggressive transmit behavior of 82579 parts when connecting

This is a workaround for a HW erratum on 82579 devices.
Erratum is #23 in Intel 6 Series Chipset and Intel C200 Series Chipset
specification Update June 2013.

Problem: 82579 parts experience packet loss in Gig and 100 speeds
when interconnect between PHY and MAC is exiting K1 power saving state.
This was previously believed to only affect 1Gig speed, but has been observed
at 100Mbs also.

Commit 4d619f62 ("net: cdc_ncm: no point in filling up the NTBs
if we send ZLPs") changed the padding logic for devices with the ZLP
flag set.  This meant that frames of any size will be sent without
additional padding, except for the single byte added if the size is
a multiple of the USB packet size. But if the unpadded size is
identical to the maximum frame size, and the maximum size is a
multiplum of the USB packet size, then this one-byte padding will
overflow the buffer.

Prevent padding if already at maximum frame size, letting usbnet
transmit a ZLP instead in this case.

In case of an error (if there are not free PEB's for example),
__wl_get_peb will return a negative value. In order to prevent access
violation we need to test the returned value prior to using it later on.

Dan's "smatch" checker found out that there was a bug in the error path of the
'ubifs_remount_rw()' function. Instead of jumping to the "out" label which
cleans-things up, we just returned.

This patch fixes the problem.

hhf_change() takes the sch_tree_lock and releases it but misses the
error cases. Fix the missed case here.

To reproduce try a command like this,

# tc qdisc change dev p3p2 root hhf quantum 40960 non_hh_weight 300000

Pull arm64 fixes from Catalin Marinas:
 "These are mostly arm64 fixes with an additional arm(64) platform fix
  for the initialisation of vexpress clocks (the latter only affecting
  arm64; the arch/arm64 code is SoC agnostic and does not rely on early
  SoC-specific calls)

   - vexpress platform clocks initialisation moved earlier following the
     arm64 move of of_clk_init() call in a previous commit
   - Default DMA ops changed to non-coherent to preserve compatibility
     with 32-bit ARM DT files.  The "dma-coherent" property can be used
     to explicitly mark a device coherent.  The Applied Micro DT file
     has been updated to avoid DMA cache maintenance for the X-Gene SATA
     controller (the only arm64 related driver with such assumption in
     -rc mainline)
   - Fixmap correction for earlyprintk
   - kern_addr_valid() fix for huge pages"

* tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux:
  vexpress: Initialise the sysregs before setting up the clocks
  arm64: Mark the Applied Micro X-Gene SATA controller as DMA coherent
  arm64: Use bus notifiers to set per-device coherent DMA ops
  arm64: Make default dma_ops to be noncoherent
  arm64: fixmap: fix missing sub-page offset for earlyprintk
  arm64: Fix for the arm64 kern_addr_valid() function
