If bus = kzalloc() fails then we end up dereferencing bus when we do
"bus->irq[i] = PHY_POLL;". The code is a little simpler if we reverse
the NULL check and return directly on failure.

Commit 1f718f0f4f ("bonding: populate neighbour's private on enslave")
undoes the fix provided by commit c2edacf80e ("bonding / ipv6: no addrconf
for slaves separately from master") by effectively setting the slave flag
after the slave has been opened. If the slave comes up quickly enough, it
will go through the IPv6 addrconf before the slave flag has been set and
will get a link local IPv6 address.
In order to ensure that addrconf knows to ignore the slave devices on state
change, set IFF_SLAVE before dev_open() during bonding enslavement.

Add exports to flow steering API for mlx5_ib usage.
The following functions are exported:
1. mlx5_create_auto_grouped_flow_table - used to create flow
table with auto flow grouping management (create and destroy
flow groups). In auto-grouped flow tables, we create groups
automatically if needed (if we don't find an existing
flow group with same match criteria when we add new rule).
2. mlx5_destroy_flow_table - used to destroy a flow table.
3. mlx5_add_flow_rule - used to add flow rule into a flow table.
4. mlx5_del_flow_rule - used to delete flow rule from its flow table.

When the driver is loaded, we create flow steering namespace
for kernel bypass with nine priorities and another namespace
for leftovers(in order to catch packets that weren't matched).
Verbs applications will use these priorities.
we found nine as a number that balances the requirements from the
user and retains performance.
The bypass namespace is used by verbs applications that want to bypass
the kernel networking stack. The leftovers namespace is used by verbs
applications and the sniffer in order to catch packets that weren't
handled by any preceding rules.

Each priority has two attributes:
1. max_ft - maximum allowed flow tables under this priority.
2. start_level - start level range of the flow tables
in the priority.
These attributes are set by traversing the tree nodes by
DFS and set start level and max flow tables to each priority.
Start level depends on the max flow tables of the prior priorities
in the tree.
The leaves of the trees have max_ft set in them. Each node accumulates
the max_ft of its children and set it accordingly.

Flow tables from different priorities should be chained together.
When a packet arrives we search for a match in the
by-pass flow tables (first we search for a match in priority 0
and if we don't find a match we move to the next priority).
If we can't find a match in any of the bypass flow-tables, we continue
searching in the flow-tables of the next priority, which are the
kernel's flow tables.
Setting the miss flow table in a new flow table to be the next one in
the list is performed via create flow table API. If we want to change an
existing flow table, for example in order to point from an
existing flow table to the new next-in-list flow table, we use the
modify flow table API.

The spew in /proc/net/bonding/bond0 uses netif_carrier_ok() to determine
mii_status, while /sys/class/net/bond0/bonding/mii_status looks at
curr_active_slave, which doesn't actually seem to be set sometimes when
the bond actually is up. A mode 4 bond configured via ifcfg-foo files on a
Red Hat Enterprise Linux system, after boot, comes up clean and
functional, but the sysfs node shows mii_status of down, while proc shows
up. A simple enough fix here seems to be to use the same method for
determining up or down in both places, and I'd opt for the one that seems
to match reality.

Dumping the FDB (invoked with a process context) or handling FDB
notifications (polled periodicly in delayed work) might each entail
multiple EMAD transcations due to the number of entries.
While we only allow one EMAD transaction at a time, there is nothing
stopping the dump and notification processing sessions from
interleaving. However, this is forbidden by the hardware, so we need to
make sure only one of these sessions can run at a time.
Solve this by adding a mutex ('fdb_lock'), as both kernel threads can
sleep while waiting for the response EMAD.

Instead of looping over the list of phy addresses to find a phy chip,
use phy_find_first(). While the intent of the original code was to return
an error if more than one phy was specified, this code path was never
executed because the loop aborted after finding the first phy. The
original code is therefore semantically identical to phy_find_first(),
thus it is simpler and more straightforward to use phy_find_first()
directly.

udp tunnel offloads tend to aggregate datagrams based on inner
headers. gro engine gets notified by tunnel implementations about
possible offloads. The match is solely based on the port number.
Imagine a tunnel bound to port 53, the offloading will look into all
DNS packets and tries to aggregate them based on the inner data found
within. This could lead to data corruption and malformed DNS packets.
While this patch minimizes the problem and helps an administrator to find
the issue by querying ip tunnel/fou, a better way would be to match on
the specific destination ip address so if a user space socket is bound
to the same address it will conflict.

the vxlan socket is done only when the interface is set up, thus it breaks
that test.
Example:
$ ip l a vxlan10 type vxlan id 10 group 239.0.0.10 dev eth0 dstport 0
$ ip l a vxlan11 type vxlan id 10 group 239.0.0.10 dev eth0 dstport 0
$ ip -br l | grep vxlan
vxlan10 DOWN f2:55:1c:6a:fb:00 <BROADCAST,MULTICAST>
vxlan11 DOWN 7a:cb:b9:38:59:0d <BROADCAST,MULTICAST>
Instead of checking sockets, let's loop over the vxlan iface list.

10GbE Intel Wired LAN Driver Updates 2016-01-08
This series contains updates to ixgbe only.
Vasu provides three fixes for ixgbe, first assigns a minimum credit to
a traffic class to resolve a Tx hang for CEE mode configuration. Second
fix changes the driver to use netdev->fcoe_ddp_xid instead of our local
IXGBE_FCOE_DDP_MAX, since it is correctly set for our different devices
and avoids a DDP skip error on X550. Lastly fix the PFC configuration
to include X550 devices.
Emil provides a fix for reporting the speed in ethtool by using the
stored value in out adapter structure. This is due to external drivers
may end up with unknown speed when calling ethtool_get_settings().
Mark fixes the handling of any outer UDP checksum, by passing the
skb up with CHECKSUM_NONE when an outer UDP checksum is set. This
will cause the stack to check the checksum, also do not increment an
error counter because we do not really know if there is an actual error.
Ixgbe ATR was not handling IPv6 extended headers, so ATR is not being
performed on such packets. Fix this by skipping extended headers
when they are present.
Usha fixes an issue with X550 and getting FDMI HBA attributes when
FCoE support is enabled.
Neerav fixes an issue for X550 when FCoE and SR-IOV are enabled, which
the hardware generates MDD events. Resolve this by setting the expected
values in the transmit context descriptors for FCoE/FIP frames and
adding a flush after writing the RDLEN register.

Right now ATR is not handling IPv6 extended headers, so ATR is not
being performed on such packets. Fix that by skipping extended
headers when they are present. This also fixes a problem where
the ATR code was not checking that the inner protocol was actually
TCP before setting up the signature rules. Since the protocol check
is intimately involved with the extended header processing as well,
this all gets fixed together.

In ixgbe_get_settings() the link status and speed of the interface
are determined based on a read from the LINKS register via the call
to mac.ops.check.link(). This can cause issues where external drivers
may end up with unknown speed when calling ethtool_get_setings().
Instead of calling the mac.ops.check_link() we can report the speed
from the adapter structure which is populated by the driver.

If the driver calls skb_set_hash even with a zero hash, that
indicates to the stack that the hash calculation is offloaded
in hardware. So the Stack doesn't do a SW hash which is required
for load balancing if the user decides to turn of rx-hashing
on our device.
This patch fixes the path so that we do not call skb_set_hash
if the feature is disabled.

This is the i40e equivalent of commit c762dff24c ("ixgbe: Look up MAC
address in Open Firmware or IDPROM").
As with that fix, attempt to look up the MAC address in Open Firmware
on systems that support it, and use IDPROM on SPARC if no OF address
is found.
In the case of the i40e there is an assumption that the default mac
address has already been set up as the primary mac filter on probe,
so if this filter is obtained from the Open Firmware or IDPROM, an
explicit write is needed via i40e_aq_mac_address_write() and
i40e_aq_add_macvlan() invocation.
The I40E_FLAG_PF_MAC flag in the platform-private i40e_pf structure
tracks whether a platform-specific mac address was found, in which
case calls to i40e_aq_mac_address_write() and i40e_aq_add_macvlan()
will be triggered.
