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.

liquidio CN23XX VF support
Following is the V6 patch series for adding VF support on
CN23XX devices. This version addressed:
1) Your concern for ordering of local variable declarations
from longest to shortest line.
2) Removed module parameters max_vfs, num_queues_per_{p,v}f.
3) Minor changes for fixing new checkpatch script related
errors on pre-existing driver.
4) Fixed compilation issues when CONFIG_PCI_IOV/CONFIG_PCI_ATS
options are disabled.
5) Modified qualifiers for printing mac addresses with pM format.
I will post remaining VF patches soon after this patchseries is
applied. Please apply patches in the following order as some of
the patches depend on earlier patches.

is executed in an "else if" check and the final "else" statement.

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

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.

The stmmac driver does not take into account the processor may be big
endian when writing the DMA descriptors. This causes the ethernet
interface not to be initialised correctly when running a big-endian
kernel. Change the descriptors for DMA to use __le32 and ensure they are
suitably swapped before writing. Tested successfully on the
Cubieboard2.

All drivers below are converted to use this new helper function. Some
