a4076d347f alx: prepare resource allocation for multi queue support
Allocate, initialise and free alx_tx_queue structs based on the number of
alx_napi structures. Also increase the size of the descriptor memory based
on the number of tx queues in use.

e0eac25460 alx: prepare interrupt functions for multiple queues
Extend the interrupt bringup code and the interrupt handler for msi-x
interrupts in order to handle multiple queues.

We must change the poll function because with multiple queues it is possible
that an alx_napi structure has only a tx or only a rx queue pointer.

b0999223f2 alx: add ability to allocate and free alx_napi structures
Add new functions to allocate and free the alx_napi structures and use them
in __alx_open and __alx_stop. We only allocate one of these structures for
now, as the rest of the driver is not yet ready for multiple queues.

We switch over the setup of the interrupt mask and the call to netif_napi_add
to the new function because we must adjust these later on a per queue basis.

8c2a4c8efb alx: refactor descriptor allocation
Split the allocation of descriptor memory and the buffer allocation into a
tx and rx function. This is in preparation for multiple queues where we
need to iterate over the new functions.

While at it drop the unneeded casting on the rx side.

====================
dpaa_eth: Add the QorIQ DPAA Ethernet driver

This patch series adds the Ethernet driver for the Freescale
QorIQ Data Path Acceleration Architecture (DPAA).

This version includes changes following the feedback received
on previous versions from Eric Dumazet, Bob Cochran, Joe Perches,
Paul Bolle, Joakim Tjernlund, Scott Wood, David Miller - thank you.

Together with the driver a managed version of alloc_percpu
is provided that simplifies the release of per-CPU memory.

The Freescale DPAA architecture consists in a series of hardware
blocks that support the Ethernet connectivity. The Ethernet driver
depends upon the following drivers that are currently in the Linux
kernel:
 - Peripheral Access Memory Unit (PAMU)
    drivers/iommu/fsl_*
 - Frame Manager (FMan) added in v4.4
    drivers/net/ethernet/freescale/fman
 - Queue Manager (QMan), Buffer Manager (BMan) added in v4.9-rc1
    drivers/soc/fsl/qbman

dpaa_eth interfaces mapping to FMan MACs:

 - remove the debug option to use a common buffer pool for all the
   interfaces

 - fixed an issue on an error path in dpaa_set_mac_address()

 - driver file structure cleanup

319b0534b9 tcp: allow to enable the repair mode for non-listening sockets
The repair mode is used to get and restore sequence numbers and
data from queues. It used to checkpoint/restore connections.

Currently the repair mode can be enabled for sockets in the established
and closed states, but for other states we have to dump the same socket
properties, so lets allow to enable repair mode for these sockets.

The repair mode reveals nothing more for sockets in other states.

====================
sun4i-emac: Fixes for running a big-endian kernel on Cubieboard2

the following patches are what remains to be fixed in order to allow running a
big-endian kernel on the Cubieboard2.

The first patch fixes up endianness problems with DMA descriptors in
the stmmac driver preventing it from working correctly when runnning a
big-endian kernel.

The second patch adds the ability to enable diagnostic messages in the
sun4i-emac driver which were instrumental in finding the problem fixed
by patch number three: Endianness confusion caused by dual-purpose I/O
register usage in sun4i-emac.

All of these have been tested successfully on a Cubieboard2 DualCard.

Changes since v4:
- Rebased to current master
- Removed already applied patches to sunxi-mmc and sunxi-Kconfig

Changes since v3:
- Rebased sunxi-mmc patch against Ulf's mmc.git/next
- Changed Kconfig change to enable big-endian support only for sun7i
  devices

Changes since v2:
- Fixed typo in stmmac patch causing a build failure
- Added sun4i-emac patches

Changes since v1:
- Fixed checkpatch niggles
- Added respective Cc:s

934d0048d0 net: ethernet: sun4i-emac: Read rxhdr in CPU byte-order
The EMAC EMAC_RX_IO_DATA_REG data register is dual-purpose: On one hand
it is used to move actual packet data off the wire. This will be in
wire-format and accepted as such by higher layers such as IP. Therefore
it is correctly read as-is (i.e. raw) using readsl.

On the other hand it provides metadata about incoming transfers to the
driver such as length and checksum validation status. This data is
little-endian, always and it is interpreted by the driver. Therefore it
needs to be swapped to CPU endianness to make sense to the driver. This
is already done for the "receive header" but not rxhdr.

Read rxhdr using readl in order for sun4i-emac to work correctly when
running a big-endian kernel.

8a29659132 Merge branch 'phy_ethtool_nway_reset'
Florian Fainelli says:

====================
net: phy: Centralize auto-negotation restart

This patch series centralizes how ethtool::nway_reset is implemented
by providing a PHYLIB function which calls into genphy_restart_aneg().

All drivers below are converted to use this new helper function. Some
other have specific requirements that make them not quite suitable for
a straight forward conversion.

There is another patch series which implements ethtool::nway_reset
using the helper function introduced that depends on this patch
series.
