fba52e21e5 i40e: Fix for truncated interrupt name
This patch extends the size of the text available for the interrupt names.
Without this patch, all the descriptive data available for the Flow
Director interrupts is truncated.

9e1c26e350 i40e/i40evf: assure clean asq status report
There was a possibility where the asq_last_status could get through without
update and thus report a previous error.  I don't think we've actually seen
this happen, but this patch will help make sure it doesn't.

21364bcfc7 i40e: make i40e_init_pf_fcoe to void
i40e_init_pf_fcoe() didn't return anything except 0, it prints enough
error info already, and no driver logic depends on the return value,
so this can be void.

0325fca757 i40e: stop VF rings
Explicitly stop the rings belonging to each VF when disabling SR-IOV.
Even though the VFs were gone, and the associated VSIs were removed, the
rings were not stopped, and in some circumstances the hardware would
continue to access the memory formerly used by the rings, causing memory
corruption or DMAR errors, both of which would lead to general malaise
of the kernel.

To relieve this condition, explicitly stop all the rings associated with
each VF before releasing its resources.

fe5c802882 s390/qeth: optimize MAC handling in rx_mode callback
In layer2 mode of the qeth driver, MAC address lists
from struct net_device require mapping to the OSA-card.
The existing implementation is inefficient for lists with
more than several MAC addresses, since for every
ndo_set_rx_mode callback it removes all MAC addresses first,
and then registers the current MAC address list.
This patch changes implementation of ndo_set_rx_mode callback
in qeth, only performing hardware registration/removal for
new/deleted addresses. To shorten lookup of MAC addresses
registered addresses are kept in a hashtable instead of a
linear list.

3e905b80b9 gianfar: Add WAKE_UCAST and "wake-on-filer" support
This enables eTSEC's filer (Rx parser) and the FGPI Rx
interrupt (Filer General Purpose Interrupt) as a wakeup
source event.

Upon entering suspend state, the eTSEC filer is given
a rule to match incoming L2 unicast packets.  A packet
matching the rule will be enqueued in the Rx ring and
a FGPI Rx interrupt will be asserted by the filer to
wakeup the system.  Other packet types will be dropped.
On resume the filer table is restored to the content
before entering suspend state.
The set of rules from gfar_filer_config_wol() could be
extended to implement other WoL capabilities as well.

The "fsl,wake-on-filer" DT binding enables this capability
on certain platforms that feature the necessary power
management infrastructure, targeting mainly printing and
imaging applications.

00a93babd0 openvswitch: add tunnel protocol to sw_flow_key
Store tunnel protocol (AF_INET or AF_INET6) in sw_flow_key. This field now
also acts as an indicator whether the flow contains tunnel data (this was
previously indicated by tun_key.u.ipv4.dst being set but with IPv6 addresses
in an union with IPv4 ones this won't work anymore).

The new field was added to a hole in sw_flow_key.

Jeff Kirsher says:

====================
Intel Wired LAN Driver Updates 2015-10-03

This series contains updates to i40e and i40evf, some of which are to
resolve more Red Hat bugzilla issues.

Jiang Liu updates the i40e and i40evf drivers to use numa_mem_id()
instead of numa_node_id() to get the nearest node with memory which
better supports memoryless nodes.

Anjali fixes an issue from Dan Carpenter <dan.carpenter@oracle.com>,
to resolve a memory leak in X722 RSS configuration path, where we should
free the memory allocated before exiting.

Shannon modifies the drivers to ensure we have the spinlocks before we
clear the ARQ and ASQ management registers.  In addition, we widen the
locked portion insert a sanity check to ensure we are working with safe
register values.

Mitch fixes an issue where under certain circumstances, we can get an
extra VF_RESOURCES message from the PF driver at runtime.  When this
occurs, we need to parse it because our VSI may have changed and that
will affect the relationship with the PF driver.  But this parsing also
blows away our current MAC address, so resolve the issue by restoring
the current MAC address from the netdev struct after we parse the
resource message.

d25b8e7429 net: dsa: better error reporting
Add additional error reporting to the generic DSA code, so it's easier
to debug when things go wrong.  This was useful when initially bringing
up 88e6176 on a new board.

4bac50bace net: dsa: mv88e6xxx: remove link polling
The link status is polled by the generic phy layer, there's no need to
duplicate that polling with additional polling.  This additional polling
adds additional MDIO traffic, and races with the generic phy layer,
resulting in missing or duplicated link status messages.

Commit ea317b267e ("bpf: Add new bpf map type to store the pointer
to struct perf_event") added perf_event.h to the main eBPF header, so
it gets included for all users. perf_event.h is actually only needed
from array map side, so lets sanitize this a bit.
