This patch:
- Clarifies the specific requirements of devices returning
CHECKSUM_UNNECESSARY (comments in skbuff.h).
- Adds csum_level field to skbuff. This is used to express how
many checksums are covered by CHECKSUM_UNNECESSARY (stores n - 1).
This replaces the overloading of skb->encapsulation, that field is
is now only used to indicate inner headers are valid.
- Change __skb_checksum_validate_needed to "consume" each checksum
as indicated by csum_level as layers of the the packet are parsed.
- Remove skb_pop_rcv_encapsulation, no longer needed in the new
csum_level model.

ii) Medium mode (takes about 2930 ms)
iii) Slow mode (takes about 7500 ms)
To run POST, firmware file with name "83xx_post_fw.bin" should be present under
/lib/firmware directory. load_fw_file module parameter is used to specify
POST operation and its speed mode.

Intel Wired LAN Driver Updates 2014-08-27
This series contains updates to i40e and i40evf.
Carolyn provides two patches, first changes the wording of the flow
director add/remove and asynchronous failure messages to include the
fd_id to try and add some way to track the operations on a given fd_id.
Second adds a check during handle_link_event for unqualified modules
when link is down and there is a module plugged in.
Anjali provides four patches to i40e/i40evf. First update flow director
messages so that a user can tell if a filter was added or deleted. Then
updates the ATR policy to not auto-disable ATR when we have errors in
programming. The disabling of ATR when we got programming errors was
buggy and was still adding new rules and causing continuous errors.
With this policy change, we flush instead when we see too many errors.
In addition she adds a flow director flush counter to ethtool to help
know how many times the interface had to flush and replay the flow
director filter table. Updates the driver to ignores a driver
perceived transmit hang if the number of descriptors pending is less
than 4, and instead log a stat when this situation happens. This is
because the queue progresses forward and the stack never experiences
a real hang in these situations.
Shannon provides three patches for i40e/i40evf, first enables the
l2tsel bit on receive queue contexts that are assigned to VFs so that
the VF can get the stripped VLAN tag. Then adds a max buffer size
parameter to the print helper to be sure the code knows when to stop.
Lastly, remove the complaint when removing the default MAC VLAN filter.
This was because old firmware had an incorrect MAC VLAN filter that
needed to be replaced at startup, and now newer firmware does not have
this problem. So now we only add the new filter if the removal
succeeded and no need to complain if the removal fails.
Ashish provides a change to vsi->num_queue_pairs to equal the number
that is configured by the VF. This limits the number of queues that
are enabled/disabled and fixes the mismatch case for when a VF
configures fewer queues than is allocated to it by the PF.

dsa: Broadcom Starfighter 2 switch support
This patch series adds support for the Broadcom Starfighter 2 (Roboswitch
successor) using the existing DSA infrastructure. This integrated switch
is heavily used in Set Top Box, Cable gateways and DSL gateways products
from Broadcom, and to a larger extent the new ARM-based Wi-Fi routers although
slightly differently.
Changes in v5 are the introduction of ETH_P_XDSA as suggested by Alexander to
help capture applications see this is a multiplexed DSA approach now.
Changes in v4 are the introducing of an indirection level for DSA switch tag
protocols receive and transmit functions.
I intentionnaly did not address one comment from Alexander who suggested to
move port_names and port_dn in a separate structure since that involves
touching arch/arm/ and arch/blackfin/ code which I am not yet comfortable
doing.
Notable changes in v3 is the preliminary patch that reworks the skb->protocol
override helpers for non-Ethertype switch tags, based on feedback from
Alexander Duyck.
The biggest changes from v1 of this patch series are:
- use the new fixed PHY helpers
- improved the switch driver with more complete features (interrupts,
(RG)MII configuration, memory arrays power down/up, port disabling/enable
VLAN separation
Future work will focus on bringing the upstream driver in feature parity with
the current downstream driver, including:
- adding Wake-on-LAN support to the switch
- adding suspend/resume callbacks for S2/S3 Power Management modes
- extending the switch register interface to cover BCM5310X SoCs

- support for the per-port MIB counters
- support for link interrupts for special ports (e.g: MoCA)
- powering up/down of switch memories to conserve power when ports are

Some platforms have special bank registers which might be used to
select the correct clock or the right mode for Media Indepent Interface

in the right order to supply the ethernet controller at the right time.
This patch is an architecture refactoring of the arc-emac device driver.
It adds a new software design which allows to add specific platform
glue layer. Each platform has now its own module which performs custom
initialization and remove for the target and then calls to the

Older firmware has an incorrect MAC VLAN filter that needs to be replaced
at startup, and now newer firmware doesn't have this problem. With this
change we no longer complain if the remove fails, and we only add the
new filter if the remove succeeded.
Setting a new LAA worked the first time, but didn't work well in successive
operations, including returning to the HW default address. This simplifies
the code that was trying to be too smart.
Lastly, this pulls the hardware default mac address out into separate
handling code and keeps the broadcast filtering from getting munged.

There is at least one case in the Firmware API where the response to a
command changes the buffer size field in the AQ descriptor to a larger
number than what the request's buffer size started as. This is in addition
to setting an error flag and is in order to tell the requester how much
larger a buffer is required for the answer. We need to be sure not to
use that number when dumping the contents of the data buffer because it
can send us into the weeds and generate an invalid pointer exception.
This patch adds a max buffer size parameter to the print helper to be
sure the code knows when to stop.

When one tries to add eth as a port into team and that eth is already in
use by other rx_handler device (macvlan, bond, bridge, ...) a bug in

team_device_event() sees IFF_TEAM_PORT and thinks that rx_handler_data

Fix this by reordering rx_handler register and IFF_TEAM_PORT priv flag
