These settings are related to a specific integration that requires
the firmware to drive some GPIOs for external RF coexistency.
Since this is really linked to specific hardware integration let's
remove them.

Neil sees this in his tests and it also triggers on pmem driver unbind
for the libnvdimm tests. This fix is on top of an initial fix by Keith
for incorrect usage of mutex_lock() in this path: 2da78092dda1 "block:
Fix dev_t minor allocation lifetime". Both this and 2da78092dda1 are
candidates for -stable.

Laptop with Turks/Thames GPU will freeze if dpm is enabled. It seems
the SMC engine is relying on some state inside the CP engine. CP needs
to chew at least one packet for it to get in good state for dynamic
power management.
This patch simply disabled and re-enable DPM after the ring test which
is enough to avoid the freeze.

When the DEBUG preprocessor macro is defined the ps3_gelic_net driver build
fails due to an undeclared routine gelic_descr_get_status(). This problem
was introduced during the code cleanup of commit
6b0c21cede22be1f68f0a632c0ca38008ce1abe7 (net: Fix p3_gelic_net sparse warnings),
which re-arranged the ordering of some of the gelic routines.
This change just moves the gelic_descr_get_status() routine up in the
ps3_gelic_net.c source file. There is no functional change.
Fixes build errors like these:

====================
net: broadcom MDIO support for broken turn-around
These two patches update the GENET and UniMAC MDIO controllers to deal with
PHYs that are known to have a broken turn-around bug (e.g: BCM53125 and others)
This utilizes the infrastructure that code recently added to do that in 'net-next'.
Note that the changes look nearly identical and I will try to address the MDIO
code duplication between GENET and UniMAC in a future patch series.
Changes in v2:
- remove brcmphy.h include in mdio-bcm-unimac.c
- use the same comment as with GENET's MDIO read function

Some Ethernet PHYs/switches such as Broadcom's BCM53125 have a hardware bug
which makes them not release the MDIO line during turn-around time. This gets
flagged by the UniMAC MDIO controller as a read failure, and we fail the read
transaction.
Check the MDIO bus phy_ignore_ta_mask bitmask for the PHY we are reading
from and if it is listed in this bitmask, ignore the read failure and
proceed with returning the data we read out of the controller.

Add PHY IDs for Davicom DM9161B and DM9161C variants.
Tested with a DM9161C on a custom Atmel-based SAM9X25 board in RMII
mode.
The DM9161B uses the same model id with just the LSB bit of the version
id changing (which is masked out).
For all intents and purposes they're the same as the DM9161A with an
added GPSI mode and better fabrication process.

Ethernet AVB device includes the gPTP timer, so we can implement a PTP clock
driver. We're doing that in a separate file, with the main Ethernet driver
calling the PTP driver's [de]initialization and interrupt handler functions.
Unfortunately, the clock seems tightly coupled with the AVB-DMAC, so when that
one leaves the operation mode, we have to unregister the PTP clock... :-(

Ethernet AVB includes an Gigabit Ethernet controller (E-MAC) that is basically
compatible with SuperH Gigabit Ethernet E-MAC. Ethernet AVB has a dedicated
direct memory access controller (AVB-DMAC) that is a new design compared to the
SuperH E-DMAC. The AVB-DMAC is compliant with 3 standards formulated for IEEE
802.1BA: IEEE 802.1AS timing and synchronization protocol, IEEE 802.1Qav real-
time transfer, and the IEEE 802.1Qat stream reservation protocol.
The driver only supports device tree probing, so the binding document is
included in this patch.

CAIA Delay-Gradient (CDG) is a TCP congestion control that modifies
the TCP sender in order to [1]:
o Use the delay gradient as a congestion signal.
o Back off with an average probability that is independent of the RTT.
o Coexist with flows that use loss-based congestion control, i.e.,
flows that are unresponsive to the delay signal.
o Tolerate packet loss unrelated to congestion. (Disabled by default.)
Its FreeBSD implementation was presented for the ICCRG in July 2012;
slides are available at http://www.ietf.org/proceedings/84/iccrg.html
Running the experiment scenarios in [1] suggests that our implementation
achieves more goodput compared with FreeBSD 10.0 senders, although it also
causes more queueing delay for a given backoff factor.
The loss tolerance heuristic is disabled by default due to safety concerns
for its use in the Internet [2, p. 45-46].
We use a variant of the Hybrid Slow start algorithm in tcp_cubic to reduce
the probability of slow start overshoot.

If CONFIG_NET_SWITCHDEV is enabled, but port driver does not implement
support for IPv4 FIB add/del ops, don't fail route add/del offload
operations. Route adds will not be marked as OFFLOAD. Routes will be
installed in the kernel FIB, as usual.
This was report/fixed by Florian when testing DSA driver with net-next on
devices with L2 offload support but no L3 offload support. What he reported
was an initial route installed from DHCP client would fail (route not
installed to kernel FIB). This was triggering the setting of
ipv4.fib_offload_disabled, which would disable route offloading after the
first failure. So subsequent attempts to install the route would succeed.
There is follow-on work/discussion to address the handling of route install
failures, but for now, let's differentiate between no support and failed
support.

When incoming packet qualifies for rx_copybreak, we copy the data to newly
allocated skb. We do not free/unmap the original buffer. At this point driver
assumes this buffer is unallocated. When enic_rq_alloc_buf() is called for
buffer allocation, it checks if buf->os_buf is NULL. If its not NULL that means
buffer can be re-used.
When vnic_rq_clean() is called for freeing all rq buffers, and if the
rx_copybreak reused buffer falls outside the used desc, we do not free the
buffer. The following trace is observer when dma-debug is enabled.
Fix is to walk through complete ring and clean if buffer is present.

In this window if an irq occurs and napi is scheduled on different cpu, it tries

dctcp_alpha can be read by from dctcp_get_info() without
synchro, so use WRITE_ONCE() to prevent compiler from using
dctcp_alpha as a temporary variable.
Also, playing with small dctcp_shift_g (like 1), can expose
an overflow with 32bit values shifted 9 times before divide.
Use an u64 field to avoid this problem, and perform the divide
only if acked_bytes_ecn is not zero.

Johannes Berg says:
====================
For this round we mostly have fixes:
* mesh fixes from Alexis Green and Chun-Yeow Yeoh,
* a documentation fix from Jakub Kicinski,
* a missing channel release (from Michal Kazior),
* a fix for a signal strength reporting bug (from Sara Sharon),
* handle deauth while associating (myself),
* don't report mangled TX SKB back to userspace for status (myself),
* handle aggregation session timeouts properly in fast-xmit (myself)
However, there are also a few cleanups and one big change that
affects all drivers (and that required me to pull in your tree)
to change the mac80211 HW flags to use an unsigned long bitmap
so that we can extend them more easily - we're running out of
flags even with a cleanup to remove the two unused ones.

SCM_SECURITY was originally only implemented for datagram sockets,
not for stream sockets. However, SCM_CREDENTIALS is supported on
Unix stream sockets. For consistency, implement Unix stream support
for SCM_SECURITY as well. Also clean up the existing code and get
rid of the superfluous UNIXSID macro.
Motivated by https://bugzilla.redhat.com/show_bug.cgi?id=1224211,
where systemd was using SCM_CREDENTIALS and assumed wrongly that
SCM_SECURITY was also supported on Unix stream sockets.

Use the timer API function setup_timer instead of structure field
assignments to initialize a timer.
A simplified version of the Coccinelle semantic patch that performs
this transformation is as follows:
@change@

-init_timer(&e1);
+setup_timer(&e1, a, 0UL);
... when != a = e2
-e1.function = a;

Since the addition of sysfs multicast router support if one set
multicast_router to "2" more than once, then the port would be added to
the hlist every time and could end up linking to itself and thus causing an
endless loop for rlist walkers.
So to reproduce just do:
echo 2 > multicast_router; echo 2 > multicast_router;
in a bridge port and let some igmp traffic flow, for me it hangs up
in br_multicast_flood().
Fix this by adding a check in br_multicast_add_router() if the port is
already linked.
The reason this didn't happen before the addition of multicast_router
sysfs entries is because there's a !hlist_unhashed check that prevents
it.

If the TIPC connection timer expires in a probing state, a
self abort message is supposed to be generated and delivered
to the local socket. This is currently broken, and the abort
message is actually sent out to the peer node with invalid
addressing information. This will cause the link to enter
a constant retransmission state and eventually reset.
We fix this by removing the self-abort message creation and
tear down connection immediately instead.

Before this patch the user-specified bridge port was ignored when
deleting an fdb entry and thus one could delete an entry that belonged
to any port.
Example (eth0 and eth1 are br0 ports):
bridge fdb add 00:11:22:33:44:55 dev eth0 master
bridge fdb del 00:11:22:33:44:55 dev eth1 master
(succeeds)
after the patch:
bridge fdb add 00:11:22:33:44:55 dev eth0 master
bridge fdb del 00:11:22:33:44:55 dev eth1 master
