ipvs: call rtnl_lock early

When the sync damon is started we need to hold rtnl
lock while calling ip_mc_join_group. Currently, we have
a wrong locking order because the correct one is
rtnl_lock->__ip_vs_mutex. It is implied from the usage
of __ip_vs_mutex in ip_vs_dst_event() which is called
under rtnl lock during NETDEV_* notifications.

Fix the problem by calling rtnl_lock early only for the
start_sync_thread call. As a bonus this fixes the usage
__dev_get_by_name which was not called under rtnl lock.

lwtunnel: Fix the sparse warnings in fib_encap_match

When CONFIG_LWTUNNEL config is not enabled, the lwtstate_free() is not
declared in lwtunnel.h at all. However, even in this case, the function
is still referenced in fib_semantics.c so that there appears the

====================
Intel Wired LAN Driver Updates 2015-08-18

This series contains updates to igb, e100, e1000e and ixgbe.

Shota Suzuki provides a fix for a possible overflow in
igb_set_interrupt_capability() which leads to an oops.  When changing the
number of queues by "ethtool -L", set IGB_FLAG_QUEUE_PAIRS in the same
manner as when initializing the igb driver.

Vasily Averin provides a fix for a missing rtnl_unlock() for when we
error out due to not being able to allocate memory for our queues.

Stefan Assman provides a couple of fixes for igb/igbvf.  First changes
the igb driver in probe to simply call igb_enable_sriov() instead of
igb_sriov_reinit() since we are starting from scratch.  Then in igbvf,
fix the driver where it does not clear the buffer_info->dma in all
cases after calling dma_unmap_single(), which was found by changing the
MTU twice.

Richard Cochran implements the periodic output function using the
programmable clock outputs available in i210 when possible, falling
back to the target time for longer periods.

Todd adds support for the Marvell PHY 1512 which is required for i354
devices.  Then updates igb to make sure SR-IOV init uses the correct
number of queues, since recent changes could result in the PF holding
onto all of the queues.

Alex Williamson provides a fix in the case where a guest OS does not
support hot-unplug, so disable SR-IOV prior to unregister_netdev() to
avoid the problem.

Jia-Ju Bai provides several patches, first knocks some collecting dust
off an old e100 driver to add a check to avoid a null pointer
dereference.  Then cleans up a possible resource leak by releasing the
skb buffer allocated when the e100_xmit_prepare() runs into an issue
in the DMA mapping.  In igb, add a missing rtnl_unlock() for when we
error out due to igb_sriov_reinit() in the igb_init_interrupt_scheme().
Provides a e1000e fix, based on suggestions from Alex Duyck to move
head/tail register writing to e1000_configure_tx/rx() to avoid a
possible null pointer dereference (similar to igb driver).  Lastly,
fix a possible memory leak in igb_probe(), where the memory shadow_vfta
allocated by kcalloc in igb_sw_init() is not freed.

Mark simplifies port-specific macros for ixgbe by eliminating explicit
comparisons with 0 and enclose formal parameters in parens to eliminate
the risk of an operator precedence issue.

D in DSA patches

The D in DSA is distributed, meaning multiple switches can be

code is broken. This patchset contains two fixes, and a small helper.

With three of more switches, the current device tree binding is not
sufficient to express the routing between the switches. The first
patch extends the binding, in a backwards compatible way, to allow a
link between a switch to describe all the switches accessible over the
link, not just the direct neighbor.

e1000e: Modify Tx/Rx configurations to avoid null pointer dereferences in e1000_open

When e1000e_setup_rx_resources is failed in e1000_open,
e1000e_free_tx_resources in "err_setup_rx" segment is executed.
"writel(0, tx_ring->head)" statement in e1000_clean_tx_ring
in e1000e_free_tx_resources will cause a null poonter dereference(crash),
because "tx_ring->head" is only assigned in e1000_configure_tx
in e1000_configure, but it is after e1000e_setup_rx_resources.

This patch moves head/tail register writing to e1000_configure_tx/rx,
which can fix this problem. It is inspired by igb_configure_tx_ring
in the igb driver.

Specially, thank Alexander Duyck for his valuable suggestion.

igb: Teardown SR-IOV before unregister_netdev()

When the .remove() callback for a PF is called, SR-IOV support for the
device is disabled, which requires unbinding and removing the VFs.
The VFs may be in-use either by the host kernel or userspace, such as
assigned to a VM through vfio-pci.  In this latter case, the VFs may
be removed either by shutting down the VM or hot-unplugging the
devices from the VM.  Unfortunately in the case of a Windows 2012 R2
guest, hot-unplug is broken due to the ordering of the PF driver
teardown.  Disabling SR-IOV prior to unregister_netdev() avoids this
issue.

igb: do not re-init SR-IOV during probe

During driver probing the following code path is triggered.
igb_probe
->igb_sw_init
  ->igb_probe_vfs
    ->igb_pci_enable_sriov
      ->igb_sriov_reinit

Doing the SR-IOV re-init is not necessary during probing since we're
starting from scratch. Here we can call igb_enable_sriov() right away.

Running igb_sriov_reinit() during igb_probe() also seems to cause
occasional packet loss on some onboard 82576 NICs. Reproduced on
Dell and HP servers with onboard 82576 NICs.

igb: Fix oops caused by missing queue pairing

When initializing igb driver (e.g. 82576, I350), IGB_FLAG_QUEUE_PAIRS is
set if adapter->rss_queues exceeds half of max_rss_queues in
igb_init_queue_configuration().
On the other hand, IGB_FLAG_QUEUE_PAIRS is not set even if the number of
queues exceeds half of max_combined in igb_set_channels() when changing
the number of queues by "ethtool -L".
In this case, if numvecs is larger than MAX_MSIX_ENTRIES (10), the size
of adapter->msix_entries[], an overflow can occur in
igb_set_interrupt_capability(), which in turn leads to an oops.

Fix this problem as follows:
 - When changing the number of queues by "ethtool -L", set
   IGB_FLAG_QUEUE_PAIRS in the same way as initializing igb driver.
 - When increasing the size of q_vector, reallocate it appropriately.
   (With IGB_FLAG_QUEUE_PAIRS set, the size of q_vector gets larger.)

Another possible way to fix this problem is to cap the queues at its
initial number, which is the number of the initial online cpus. But this
is not the optimal way because we cannot increase queues when another
cpu becomes online.

Note that before commit cd14ef54d25b ("igb: Change to use statically
allocated array for MSIx entries"), this problem did not cause oops
but just made the number of queues become 1 because of entering msi_only
mode in igb_set_interrupt_capability().

Merge branch 'drivers_iff_no_queue'

Phil Sutter says:

====================
net: Convert drivers to IFF_NO_QUEUE and cleanup afterwards

This series converts in-tree users away from the old and deprecated
'tx_queue_len = 0' idiom, adds a warning to notify out-of-tree driver
maintainers that there is need for action on their behalf and finally drops any
workarounds in scheduling algorithm implementations.

net: sched: drop all special handling of tx_queue_len == 0

Those were all workarounds for the formerly double meaning of
tx_queue_len, which broke scheduling algorithms if untreated.

Now that all in-tree drivers have been converted away from setting
tx_queue_len = 0, it should be safe to drop these workarounds for
categorically broken setups.

net: warn if drivers set tx_queue_len = 0

Due to the introduction of IFF_NO_QUEUE, there is a better way for
drivers to indicate that no qdisc should be attached by default. Though,
the old convention can't be dropped since ignoring that setting would
break drivers still using it. Instead, add a warning so out-of-tree
driver maintainers get a chance to adjust their code before we finally
get rid of any special handling of tx_queue_len == 0.
