net, phy, smsc: add posibility to disable energy detect mode
On some boards the energy enable detect mode leads in
trouble with some switches, so make the enabling of
this mode configurable through DT.
Therefore the property "smsc,disable-energy-detect" is
introduced.
Patch 1 introduces phy-handle support for the ti,cpsw
driver. This is needed now for the smsc phy.
Patch 2 adds the disable energy mode functionality
to the smsc phy
Changes in v2:
- add comments from Florian Fainelli
- I did not change disable property name into enable
because I fear to break existing behaviour
- add smsc vendor prefix
- remove CONFIG_OF and use __maybe_unused
- introduce "phy-handle" ability into ti,cpsw
driver, so I can remove bogus:
if (!of_node && dev->parent->of_node)
of_node = dev->parent->of_node;
construct. Therefore new patch for the ti,cpsw
driver is necessary.

Intel Wired LAN Driver Updates 2015-10-19
This series contains updates to i40e and i40evf only.
Kiran adds a spinlock around code accessing VSI MAC filter list to
ensure that we are synchronizing access to the filter list, otherwise
we can end up with multiple accesses at the same time which can cause
the VSI MAC filter list to get in an unstable or corrupted state.
Jesse fixes overlong BIT defines, where the RSS enabling call were
mistakenly missed. Also fixes a bug where the enable function was
enabling the interrupt twice while trying to update the two interrupt
throttle rate thresholds for Rx and Tx, while refactoring the IRQ
enable function to simplify reading the flow. Addressed the high
CPU utilization of some small streaming workloads that the driver should
reduce CPU in.
Anjali fixes two X722 issues with respect to EEPROM checksum verify and
reading NVM version info. Fixed where a mask value was accidentally
replaced with a bit mask causing Flow Director sideband to be broken.
Alex Duyck fixes areas of the drivers which run from hard interrupt

to communicate with the PF driver.
Carolyn fixes a problem where our tools MAC loopback test, after driver
unbind would fail because the hardware was configured for multiqueue and
unbind operation did not clear this configuration. Also fixed a issue
where the NVMUpdate tool gets bad data from the PHY when using the PHY
NVM feature because of contention on the MDIO interface from getting
PHY capability calls from the driver during regular operations.

The hci_conn objects don't have a dedicated lock themselves but rely
on the caller to hold the hci_dev lock for most types of access. The
hci_conn_timeout() function has so far sent certain HCI commands based
on the hci_conn state which has been possible without holding the
hci_dev lock.
The recent changes to do LE scanning before connect attempts added
even more operations to hci_conn and hci_dev from hci_conn_timeout,
thereby exposing potential race conditions with the hci_dev and
hci_conn states.
As an example of such a race, here there's a timeout but an
l2cap_sock_connect() call manages to race with the cleanup routine:

Above the l2cap_chan_connect() shouldn't have been able to reach the
hci_conn f53d56e0 anymore but since hci_conn_timeout didn't do proper
locking that's not the case. The end result is a reference to hci_conn
that's not in the conn_hash list, resulting in list corruption when
trying to remove it later:
[Oct21 08:15] l2cap_chan_timeout: chan ee4b1770 state BT_CONNECT

The necessary fix is unfortunately more complicated than just adding
hci_dev_lock/unlock calls to the hci_conn_timeout() call path.
Particularly, the hci_conn_del() API, which expects the hci_dev lock to
be held, performs a cancel_delayed_work_sync(&hcon->disc_work) which
would lead to a deadlock if the hci_conn_timeout() call path tries to
acquire the same lock.
This patch solves the problem by deferring the cleanup work to a
separate work callback. To protect against the hci_dev or hci_conn
going away meanwhile temporary references are taken with the help of
hci_dev_hold() and hci_conn_get().

There is a L2CAP protocol race between the local peer and
the remote peer demanding disconnection of the L2CAP link.
When L2CAP ERTM is used, l2cap_sock_shutdown() can be called
from userland to disconnect L2CAP. However, there can be a
delay introduced by waiting for ACKs. During this waiting
period, the remote peer may have sent a Disconnection Request.
Therefore, recheck the shutdown status of the socket
after waiting for ACKs because there is no need to do
further processing if the connection has gone.

This commit reorganizes the mutex lock and is now
only protecting l2cap_chan_close(). This is now consistent
with other places where l2cap_chan_close() is called.
If a conn connection exists, call
mutex_lock(&conn->chan_lock) before calling l2cap_chan_close()
to ensure other L2CAP protocol operations do not interfere.
Note that the conn structure has to be protected from being
freed as it is possible for the connection to be disconnected
whilst the locks are not held. This solution allows the mutex
lock to be used even when the connection has just been
disconnected.
This commit also reduces the scope of chan locking.
The only place where chan locking is needed is the call to
l2cap_chan_close(chan, 0) which if necessary closes the channel.
Therefore, move the l2cap_chan_lock(chan) and
l2cap_chan_lock(chan) locking calls to around
l2cap_chan_close(chan, 0).
This allows __l2cap_wait_ack(sk, chan) to be called with no
chan locks being held so L2CAP messaging over the ACL link
can be done unimpaired.

This patch reworks the handling of compression/decompression of traffic
class and flow label handling. The current method is hard to understand,
also doesn't checks if we can read the buffer from skb length.
I tried to put the shifting operations into static inline functions and
comment each steps which I did there to make it hopefully somewhat more
readable. The big mess to deal with that is the that the ipv6 header
bring the order "DSCP + ECN" but iphc uses "ECN + DSCP". Additional the
DCSP + ECN bits are splitted in ipv6_hdr inside the priority and
flow_lbl[0] fields.
I tested these compressions by using fakelb 802.15.4 driver and
manipulate the tc and flow label fields manually in function
"__ip6_local_out" before the skb will be send to lower layers. Then I
looked up the tc and flow label fields in wireshark on a wpan and lowpan
interface.

This patch changes the lowpan_header_decompress function by removing

The address parameters are also changed to a void pointer, so 6LoWPAN
linklayer specific code can put complex structures as these parameters
and cast it again inside the generic code by evaluating linklayer type
before. The order is also changed by destination address at first and
then source address, which is the same like all others functions where
destination is always the first, memcpy, dev_hard_header,

The commit 89cbb0638e introduced support for deferred connection
parameter removal when unpairing by removing them only once an
existing connection gets disconnected. However, it failed to address
the scenario when we're *not* connected and do an unpair operation.
What makes things worse is that most user space BlueZ versions will
first issue a disconnect request and only then unpair, meaning the
buggy code will be triggered every time. This effectively causes the
kernel to resume scanning and reconnect to a device for which we've
removed all keys and GATT database information.

The HIDP specs define an idle-timeout which automatically disconnects a
device. This has always been implemented in the HIDP layer and forced a
synchronous shutdown of the hidp-scheduler. This works just fine, but
lacks a forced disconnect on the underlying l2cap channels. This has been
broken since:

Author: David Herrmann <dh.herrmann@gmail.com>

Bluetooth: hidp: remove old session-management
The old session-management always forced an l2cap error on the ctrl/intr
channels when shutting down. The new session-management skips this, as we
don't want to enforce channel policy on the caller. In other words, if
user-space removes an HIDP device, the underlying channels (which are
*owned* and *referenced* by user-space) are still left active. User-space
needs to call shutdown(2) or close(2) to release them.
Unfortunately, this does not work with idle-timeouts. There is no way to
signal user-space that the HIDP layer has been stopped. The API simply
does not support any event-passing except for poll(2). Hence, we restore
old behavior and force EUNATCH on the sockets if the HIDP layer is
disconnected due to idle-timeouts (behavior of explicit disconnects
remains unmodified). User-space can still call
getsockopt(..., SO_ERROR, ...)
..to retrieve the EUNATCH error and clear sk_err. Hence, the channels can
still be re-used (which nobody does so far, though). Therefore, the API
still supports the new behavior, but with this patch it's also compatible
to the old implicit channel shutdown.

The change to bpa10x to use the h4_recv_buf helper added a dependency

warning: (BT_HCIBPA10X) selects BT_HCIUART which has unmet direct dependencies (NET && BT && TTY)

This replaces the 'select BT_HCIUART' dependency with 'depends on', which
does not have this kind of problem. Alternatively, one could add 'depends
on TTY', but avoiding 'select' on user-visible options is generally the
preferred choice as that does not introduce the potential for dependency
