In uap mode the carrier is not enabled until after the first STA joins.
The carrier triggers the bridge to start its state machine, and if STP
is enabled, it takes 4 seconds as it transitions from disabled to
forwarding. During this time the bridge drops all traffic, and the EAPOL
handshake times out after 3 seconds, preventing stations from joining.
Follow the logic used in mac80211 and start the carrier in start_ap
and disable it in stop_ap. This has a nice benefit of allowing the
first station connection time to be reduced by up to 75% when STP is
in use.

wcn36xx implements a ring buffer for transmitted frames for each
(high and low priority) DMA channel. The ring buffers are lockless:
new frames are inserted at the head of the queue, while finished
packets are reaped from the tail.
Unfortunately, the list manipulations are missing any kind of barriers
so are susceptible to various races: for example, a TX completion
handler might read an updated desc->ctrl before the head has actually
advanced, and then null out the ctl->skb pointer while it is still
being used in the TX path.
Simplify things here by adding a spin lock when traversing the ring.
This change increased stability for me without adding any noticeable
overhead on my platform (xperia z).

Some of the ath9k_phyerr enums were wrong from the
beginning (and even before). Most of the time the
codes were used for counters to be displayed over
debugfs, which made this a non-functional issue.
Some (e.g. ATH9K_PHYERR_FALSE_RADAR_EXT) are used
for radar detection and require the correct code
to work as intended.
This patch includes:
a) fixes
ATH9K_PHYERR_FALSE_RADAR_EXT: 24 => 36
ATH9K_PHYERR_CCK_LENGTH_ILLEGAL: 32 => 28
ATH9K_PHYERR_CCK_POWER_DROP: 33 => 29
ATH9K_PHYERR_HT_CRC_ERROR: 34 => 32
ATH9K_PHYERR_HT_LENGTH_ILLEGAL: 35 => 33
ATH9K_PHYERR_HT_RATE_ILLEGAL: 36 => 34
b) extensions
ATH9K_PHYERR_CCK_BLOCKER = 24
ATH9K_PHYERR_HT_ZLF = 35
ATH9K_PHYERR_GREEN_FIELD = 37
Aside from the correction and completion made in
the enum, the patch also extends the display of
the related counters in the debugfs.

SIOCSIWAP is present in scan results.
This makes NetworkManager work for the first time but then unable to
find any other APs.

I'm planning to create similar directories for all vendors, currently we
just have ath, mediatek and realtek. This change has been in linux-next
for a couple of weeks so it should be safe, but of course you never
know.
There's also a new driver rtl8xxxu for few realtek USB devices. This
just made it to the last linux-next build.
Otherwise there's nothing really special, more info below. If time
permits, and it's ok for you, I'm hoping to send you a one more pull
request this week.

This patch adds support for dumping a process' (classic BPF) seccomp
filters via ptrace.
PTRACE_SECCOMP_GET_FILTER allows the tracer to dump the user's classic BPF
seccomp filters. addr should be an integer which represents the ith seccomp
filter (0 is the most recently installed filter). data should be a struct
sock_filter * with enough room for the ith filter, or NULL, in which case
the filter is not saved. The return value for this command is the number of
BPF instructions the program represents, or negative in the case of errors.
Command specific errors are ENOENT: which indicates that there is no ith
filter in this seccomp tree, and EMEDIUMTYPE, which indicates that the ith
filter was not installed as a classic BPF filter.
A caveat with this approach is that there is no way to get explicitly at
the heirarchy of seccomp filters, and users need to memcmp() filters to
decide which are inherited. This means that a task which installs two of
the same filter can potentially confuse users of this interface.
v2: * make save_orig const
* check that the orig_prog exists (not necessary right now, but when
grows eBPF support it will be)
* s/n/filter_off and make it an unsigned long to match ptrace
* count "down" the tree instead of "up" when passing a filter offset
v3: * don't take the current task's lock for inspecting its seccomp mode
* use a 0x42** constant for the ptrace command value
v4: * don't copy to userspace while holding spinlocks
v5: * add another condition to WARN_ON
v6: * rebase on net-next

mpls: mulipath improvements
Two improvements to the recently added mpls multipath support. The
first is a fix for missing initialisation the nexthop address length
for the v4 and v6 explicit null label routes, and the second is to
reduce the amount of memory used by mpls routes by changing the way
the via addresses are stored.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

Nexthops for MPLS routes have a via address field sized for the
largest via address that is expected, which is 32 bytes. This means
that in the most common case of having ipv4 via addresses, 28 bytes of
memory more than required are used per nexthop. In the other common
case of an ipv6 nexthop then 16 bytes more than required are
used. With large numbers of MPLS routes this extra memory usage could
start to become significant.
To avoid allocating memory for a maximum length via address when not
all of it is required and to allow for ease of iterating over
nexthops, then the via addresses are changed to be stored in the same
memory block as the route and nexthops, but in an array after the end
of the array of nexthops. New accessors are provided to retrieve a
pointer to the via address.
To allow for O(1) access without having to store a pointer or offset
per nh, the via address for each nexthop is sized according to the
maximum via address for any nexthop in the route, which is stored in a
new route field, rt_max_alen, but this is in an existing hole in
struct mpls_route so it doesn't increase the size of the
structure. Each via address is ensured to be aligned to VIA_ALEN_ALIGN
to account for architectures that don't allow unaligned accesses.

netstamp_needed is toggled for all socket families if they request
timestamping. But some protocols don't need the lower-layer timestamping
code at all. This patch starts disabling it for af-unix.
E.g. systemd enables timestamping during boot-up on the journald af-unix
sockets, thus causing the system to globally enable timestamping in the
lower networking stack. Still, it is very probable that timestamping
gets activated, by e.g. dhclient or various NTP implementations.

Add new drivers: qed & qede
This series implements the driver set for Qlogic's new QL4xxx series.
These are 10/20/25/40/50/100 Gig capable converged nics, supporting
ethernet (obviously), iscsi, fcoe, roce and iwarp protocols.
The overall driver design includes a common module ('qed') and protocol
specific dependent modules for ethernet ('qede'), fcoe ('qedf'),
iscsi ('qedi') and roce ('qedr').
The common module contains all of the common logic, e.g. initialization,
cleanup, infrastructure for interrupt handling, link management, slowpath
etc. as well as protocol agnostic features, and supplying an abstraction
layer for other modules.
The protocol specific modules can be compiled and operated independently
of each other, with the exception of the rdma modules which are dependent
on the ethernet module, in accordance with the kernel rdma stack design.
This series only adds the core and ethernet modules, with basic L2
capabilities. Future series will add the rest of the modules and enhance
the L2 functionality.
Ths patch series is constructed of the following patches:
qed: Add module with basic common support
qed: Add basic L2 interface
qede: Add basic Network driver
qed: Add slowpath L2 support
qede: Add basic network device support
qede: Add classification configuration
qed: Add link support
qede: Add support for link
qed: Add statistics support
qede: Add basic ethtool support
This project is a team effort, thanks go to Yuval Mintz, Dmitry Kravkov,
Michal Kalderon, Tomer Tayar, Manish Chopra, Sudarsana Kalluru,
Rajesh Borundia, Sony Chacko, Artum Zolotushko, Harish Patil, Rasesh Mody,
Sergey Ukhterov and Elad Manela, as well as former team members,
Eilon Greenstein and Shmulik Ravid.
Changes from previos version:
-----------------------------
From Version 7:
- Various small fixes according to Dave's suggestions; Largest change
[code-wise] - don't use tabs for indenting function arguments.
From Version 6:
- Reduced the number of arguments for functions with exceptionally
high number of parameters.
From Version 5:
- Style change and fixes [mostly in 1, 4 and 7].
Thanks go to Francois Romieu, a mere mortal. ;-)
From Version 4:
- Drop dependency for x86_64.
From Version 3:
- Limit support of initial submission to x86_64.
- Fix endian problems appearing via sparse [although no BE support yet].
- Fix small issues suggested by the kbuild test robot.
From Version 2:
- Removed U64_{HI,LO}; Using {upper,lower}_32_bits instead.
- Use regular napi weight definition.
- [We still use the __le variants for variables, since we didn't get
a reply regarding the change into non-user API types].
From Version 1:
- Removed private license file; Instead revised comments at source headers.

The Qlogic Everest Driver is the backend module for the QL4xxx ethernet
products by Qlogic.
This module serves two main purposes:
1. It's responsible to contain all the common code that will be shared
between the various drivers that would be used with said line of
products. Flows such as chip initialization and de-initialization
fall under this category.
2. It would abstract the protocol-specific HW & FW components, allowing
the protocol drivers to have a clean APIs which is detached in its
slowpath configuration from the actual HSI.
This adds a very basic module without any protocol-specific bits.
I.e., this adds a basic implementation that almost entirely falls under
the first category.

While the current driver mostly supports BCM7445 which has a hardcoded
location for its MoCA port on port 7 and port 0 for its internal PHY,
this is not necessarily true for all other chips out there such as
BCM3390 for instance.
Walk the list of ports from Device Tree, get their port number ("reg"
property), and then parse the "phy-mode" property and initialize two
internal variables: moca_port and a bitmask of internal PHYs. Since we
use interrupts for the MoCA port, we introduce two helper functions to
enable/disable interrupts and do this at the appropriate bank (INTRL2_0
or INTRL2_1).

The EAE PLX-PCI card has a special rotary encoder
to configure the address of every card individually.
We take this information for the initial setup of
the cards dev_id.

This patch sets the dev_port according to the index of
the card. This can be used by udev to name the ports
in userspace.

This patch changes the driver to properly work with the linux netif
interface. The controller gets enabled on open and disabled on close.
Therefor it removes every bogus start of the xceiver. It only gets
enabled on com20020_open and disabled on com20020_close.

The call for dev_free_skb is done only once. This patch
moves its call to its only user and removes the obsolete
condition variable.

bnxt_gro_skb() has unused variables when CONFIG_INET is not set. We
really cannot support hardware GRO if CONFIG_INET is not set, so
compile out bnxt_gro_skb() completely and define BNXT_FLAG_GRO to be 0
if CONFIG_INET is not set. This will effectively always disable
hardware GRO if CONFIG_INET is not set.

This fixes the mask used to update the LED configuration so that it clears
the necessary bits as well as setting the bits according to the mask.
Also reverse the LED configuration to show the Link state + collisions in
LEDA and the Link state + TX/RX events in LEDB.

====================
mvneta ethtool statistics
Sorry for v3 - I forgot to update the commit message on patch 1 as
requested by Marcin.
This short series adds ethtool statistics reporting to mvneta. Having
discussed with Andrew on IRC, we decided I'd pick up his patch into my
series.
My change for patch 1 compared to the previous RFC splits out the
reading of the statistics from the hardware into a separate function,
in order to facilitate work going on elsewhere to arrange for the
statistics to be preserved across a suspend/resume cycle.

The existing function to clear the MIB statatistics was using the
wrong address for the registers. Also, the counters would of been
cleared when the interface was brought up, not during the
probe. Fix both of these.

poll(POLLOUT) on a listener should not report fd is ready for
a write().
This would break some applications using poll() and pfd.events = -1,
as they would not block in poll()
