Based on a quick test with AR9271, TDLS seems to be working fine.
Tests were done with 2 Atheros AR9271 based devices with firmware
1.3 (sha1 8d49f928aa40ac53c729189bff1333cd373a7fb5), associated
with a WAP54G access point. TDLS worked fine both in WPA2 mode and
without encryption. Stations maintained ping flood traffic between
each other and towards the AP without significant losses.
Not tested with AR7010.
TDLS was enabled in earlier patches the same way for other
Atheros drivers:
ath9k (fd6562344d),
and carl9170 (d1f3de71a5).

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

Add support for the Broadcom Starfigther 2 switch chip using a DSA

- configuration of the external switch port interface: MII, RevMII,
RGMII and RGMII_NO_ID are supported
- 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
unused
Finally, update the compatible property for the DSA core code to match
our switch top-level compatible node.

Some platforms have special bank registers which might be used to
select the correct clock or the right mode for Media Indepent Interface
controllers. Sometimes, it is also required to activate vcc regulators
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
core driver.

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.

Instead of disabling ATR when we get a programming error, we now
will wait it out to see if some room gets created by ATR rule deletion.
If we still have too many errors and ATR filter count did not change
much, its time to flush and replay. We no more auto-disable ATR when
we have errors in programming.
The disabling of ATR when we get programming error 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.
ATR is still disabled if we add a SB rule for TCP/IPv4 flow type,
more logic is added to re-enable it once all SB TCP/IPv4 rules are gone.
