vrf: remove slave queue and private slave struct
The private slave queue and slave struct haven't been used for anything

enslave/release. We can use netdev_for_each_lower_dev() to free the vrf

Intel Wired LAN Driver Updates 2015-11-23
This series contains updates to ixgbe, ixgbevf, fm10k, i40e and i40evf.
Jacob fixes an issue where VF could attempt to read queues it does not own,
so prevent this we check queue 0 before we continue.
Matthew fixes the MTU for jumbo frames for fm10k.
Julia Lawall cleans up a unneeded NULL test in ixgbe.
Mark cleans up a redundant header inclusion. Adds KR mode support for
CS4227 chip. Cleaned up diagnostic code, which is no longer needed, for
the CS4227 chip.
Jean Sacren fixes kernel documentation for ixgbe.
Alex Duyck fixes an fm10k and ixgbe issue in which the polling routine would
increase the budget for receive to at least 1 per queue if multiple queues were
present. This would result in receive packets being processed when the budget
was 0 which is meant to indicate that no receive can be handled. Also fixes
an ixgbevf performance issue where netperf test will starve for memory in the
time form one transmit interrupt to the next, so limit lowest interrupt rate
for adaptive interrupt moderation to 12K. Fixed up ixgbe and ixgbevf to
use napi_schedule_irqoff() where the drivers were run from hard interrupt
context or with interrupts already disabled in netpoll.
Jesse fixes a compiler warning about an unused variable for i40evf.
John Greene fixes an issue with ixgbevf, where if the VF driver is loaded
while the corresponding PH interface is down, the driver assigns a random
MAC address, can be overwritten with the value of hw->mac.perm_addr which
is 0 at that point. So avoid this case by initializing hw->mac.perm_addr
to the randomly generated address and do not set it unless we receive an
ACK from ixgbe.

====================
improve fault-tolerance of rhashtable runtime-test
The following series aims to improve lib/test_rhashtable in different
situations:
Patch 1 allows the kernel to reschedule so the test does not block too
long on slow systems.
Patch 2 fixes behaviour under pressure, retrying inserts in non-permanent
error case (-EBUSY).
Patch 3 auto-adjusts the upper table size limit according to the number
of threads (in concurrency test). In fact, the current default is
already too small.
Patch 4 makes it possible to retry inserts even in supposedly permanent
error case (-ENOMEM) to expose rhashtable's remaining problem of
-ENOMEM being not as permanent as it is expected to be.
Changes since v1:
- Introduce insert_retry() which is then used in single-threaded test as
well.
- Do not retry inserts by default if -ENOMEM was returned.
- Rename the retry counter to be a bit more verbose about what it
contains.
- Add patch 4 as a debugging aid.

tipc: convert node lock to rwlock
According to the node FSM a node in state SELF_UP_PEER_UP cannot
change state inside a lock context, except when a TUNNEL_PROTOCOL
(SYNCH or FAILOVER) packet arrives. However, the node's individual
links may still change state.
Since each link now is protected by its own spinlock, we finally have
the conditions in place to convert the node spinlock to an rwlock_t.
If the node state and arriving packet type are rigth, we can let the
link directly receive the packet under protection of its own spinlock
and the node lock in read mode. In all other cases we use the node
lock in write mode. This enables full concurrent execution between
parallel links during steady-state traffic situations, i.e., 99+ %
of the time.

tipc: small cleanup of function tipc_node_check_state()
The function tipc_node_check_state() contains the core logics
for handling link synchronization and failover. For this reason,
it is important to keep it as comprehensible as possible.
In this commit, we make three small cleanups.
1) If the node is in state SELF_DOWN_PEER_LEAVING and the received
packet confirms that the peer has lost contact, there will be no
further action in this function. To make this clearer, we return
from the function directly after the state change.
2) Since commit
0f8b8e28fb3241f9fd ("tipc: eliminate risk of stalled
link synchronization") only the logically first TUNNEL_PROTO/SYNCH
packet can alter the link state and set the synch point,
independently of arrival order. Hence, there is not any longer any
need to adjust the synch value in case such packets arrive in
disorder. We remove this adjustment.
3) It is the intention that any message arriving on any of the links
may trig a check for and possible termination of a node SYNCH state.
A redundant and unnoticed check for tipc_link_is_synching() obviously
beats this purpose, with the effect that only packets arriving on the
synching link may currently end the synch state. We remove this check.
This change will further shorten the synchronization period between
parallel links.

Bluetooth: Simplify request cleanup code
The hci_req_sync_cancel() is just as much related to the request
cleanup as hci_request_cancel_all() is. Just move the former into the
latter and do the cleanup from a single place in hci_dev_do_close().
The important thing is to avoid deadlocks by holding the req_sync
lock: previously hci_request_cancel_all was done right after releasing
the lock and with this patch it's right before taking it.

Bluetooth: Fix specifying role for LE connections
The hci_connect_le_scan() is (as the name implies) a master/central
role API, so it makes no sense in passing a role parameter to it. At
the same time this patch also fixes the direct advertising support for
LE L2CAP sockets where we now call the more appropriate hci_le_connect()
API if slave/peripheral role is desired.

Bluetooth: Move Stop Discovery to req_workqueue
Since discovery also deals with LE scanning it makes sense to move it
behind the same req_workqueue as other LE scanning changes. This also
simplifies the logic since we do many of the actions in a synchronous
manner.
Part of this refactoring is moving hci_req_stop_discovery() to
hci_request.c. At the same time the function receives support for
properly handling the STOPPING state since that's the state we'll be
in when stopping through the req_workqueue.
