On some arm-based platforms, we need to configure platform specific
parameters by device tree node and also define our node as a child
node of parent SDIO host controller.
This patch parses these parameters from device tree. It includes
calibration data download to firmware, wakeup pin configured to firmware,
and soc specific wake up gpio, which will be set as wakeup interrupt pin.

40GbE Intel Wired LAN Driver Updates 2016-05-01
This series contains updates to i40e and i40evf.
The theme of this series is code reduction, with several code cleanups in
this series. Starting with Neerav's removal of the code that implemented
the HMC AQ APIs and calls, since they are now obsolete and not supported
by firmware.
Anjali changes the default of VFs to make sure they are not trusted or
privileged until its explicitly set for trust through the new NDO op
interface. Also limited the number of MAC and VLAN addresses a VF can
add if it is untrusted/privileged.
Carolyn syncs the VF code for the changes made to the PF for the RSS
hash tuple settings, which ends up cleaning up much of the existing code.
Jesse cleans up compiler warnings which were found with gcc's W=2 option.
Then removed duplicate code, especially since only one copy was actually
being used.
Jacob addresses an issue which was found when testing GCC 6's which
happens to produce new warnings when you left shift a signed value
beyond the storage sizeof the type. The converts i40e & i40evf to use
the BIT() macro more consistently.
Alex actually bucks the trend of code removal by adding support for
both drivers to use GSO_PARTIAL so that segmentation of frames with
checksums enabled in outer headers is supported. Fortunately it does
not take much to add this support!

Prior to commit d92cff89a0 ("net_dbg_ratelimited: turn into no-op
when !DEBUG") the implementation of net_dbg_ratelimited() was buggy
for both the DEBUG and CONFIG_DYNAMIC_DEBUG cases.
The bug was that net_ratelimit() was being called and, despite
returning true, nothing was being printed to the console. This
resulted in messages like the following -
"net_ratelimit: %d callbacks suppressed"
with no other output nearby.
After commit d92cff89a0 ("net_dbg_ratelimited: turn into no-op when
!DEBUG") the bug is fixed for the DEBUG case. However, there's no
output at all for CONFIG_DYNAMIC_DEBUG case.
This patch restores debug output (if enabled) for the
CONFIG_DYNAMIC_DEBUG case.
Add a definition of net_dbg_ratelimited() for the CONFIG_DYNAMIC_DEBUG
case. The implementation takes care to check that dynamic debugging is
enabled before calling net_ratelimit().

This patch thus basically inverts the logic on fb586f2530 and signals
it as early as possible, similar to what we had before.

We have observed complete lock up of broadcast-link transmission due to
unacknowledged packets never being removed from the 'transmq' queue. This
is traced to nodes having their ack field set beyond the sequence number
of packets that have actually been transmitted to them.
Consider an example where node 1 has sent 10 packets to node 2 on a
link and node 3 has sent 20 packets to node 2 on another link. We
see examples of an ack from node 2 destined for node 3 being treated as
an ack from node 2 at node 1. This leads to the ack on the node 1 to node
2 link being increased to 20 even though we have only sent 10 packets.
When node 1 does get around to sending further packets, none of the
packets with sequence numbers less than 21 are actually removed from the
transmq.
To resolve this we reinstate some code lost in commit d999297c3d ("tipc:
reduce locking scope during packet reception") which ensures that only
messages destined for the receiving node are processed by that node. This
prevents the sequence numbers from getting out of sync and resolves the
packet leakage, thereby resolving the broadcast-link transmission
lock-ups we observed.
While we are aware that this change only patches over a root problem that
we still haven't identified, this is a sanity test that it is always
legitimate to do. It will remain in the code even after we identify and
fix the real problem.

Since commit b74766a0a0 ("phylib: don't return NULL
from get_phy_device()") in linux-next, phy_get_device() will return
ERR_PTR(-ENODEV) instead of NULL if the PHY device ID is all ones.
This causes problem with stmmac driver and likely some other drivers
which call mdiobus_register(). I triggered this bug on SoCFPGA MCVEVK
board with linux-next 20160427 and 20160428. In case of the stmmac, if
there is no PHY node specified in the DT for the stmmac block, the stmmac
driver ( drivers/net/ethernet/stmicro/stmmac/stmmac_mdio.c function
stmmac_mdio_register() ) will call mdiobus_register() , which will
register the MDIO bus and probe for the PHY.
The mdiobus_register() resp. __mdiobus_register() iterates over all of
the addresses on the MDIO bus and calls mdiobus_scan() for each of them,
which invokes get_phy_device(). Before the aforementioned patch, the
mdiobus_scan() would return NULL if no PHY was found on a given address
and mdiobus_register() would continue and try the next PHY address. Now,
mdiobus_scan() returns ERR_PTR(-ENODEV), which is caught by the
'if (IS_ERR(phydev))' condition and the loop exits immediately if the
PHY address does not contain PHY.
Repair this by explicitly checking for the ERR_PTR(-ENODEV) and if this
error comes around, continue with the next PHY address.

This patch makes it so that i40e and i40evf can use GSO_PARTIAL to support
segmentation for frames with checksums enabled in outer headers. As a
result we can now send data over these types of tunnels at over 20Gb/s
versus the 12Gb/s that was previously possible on my system.
The advantage with the i40e parts is that this offload is mostly
transparent as the hardware still deals with the inner and/or outer IPv4
headers so the IP ID is still incrementing for both when this offload is
performed.

Add a check whether the 'struct device_node' pointer passed to
of_mdiobus_register() is an available (aka enabled) node in the Device
Tree.
Rationale for doing this are cases where an Ethernet MAC provides a MDIO
bus controller and node, and an additional Ethernet MAC might be
connecting its PHY/switches to that first MDIO bus controller, while
still embedding one internally which is therefore marked as "disabled".
Instead of sprinkling checks like these in callers of
of_mdiobus_register(), do this in a central location.

This patch fixes a bug which causes the behavior of whether to ignore
udp6 checksum of udp6 encapsulated l2tp tunnel contrary to what
userspace program requests.
When the flag `L2TP_ATTR_UDP_ZERO_CSUM6_RX` is set by userspace, it is
expected that udp6 checksums of received packets of the l2tp tunnel
to create should be ignored. In `l2tp_netlink.c`:
`l2tp_nl_cmd_tunnel_create()`, `cfg.udp6_zero_rx_checksums` is set
according to the flag, and then passed to `l2tp_core.c`:
`l2tp_tunnel_create()` and then `l2tp_tunnel_sock_create()`. In
`l2tp_tunnel_sock_create()`, `udp_conf.use_udp6_rx_checksums` is set
the same to `cfg.udp6_zero_rx_checksums`. However, if we want the
checksum to be ignored, `udp_conf.use_udp6_rx_checksums` should be set
to `false`, i.e. be set to the contrary. Similarly, the same should be
done to `udp_conf.use_udp6_tx_checksums`.

pull request up. These are all small and I've got this kernel built

====================
Mellanox 100G mlx5 ethernet aRFS support
This series adds accelerated RFS support for the mlx5e driver.
I have added one patch non-related to aRFS that fixes the rtnl_lock
warning mlx5 driver been getting since b7aade1548 ('vxlan: break dependency with netdev drivers')
aRFS support in details:
A direct TIR per RQ is now required in order to have the essential building blocks
for aRFS. Today the driver has one direct TIR that forwards traffic to RQ[0] (core 0),
and one indirect TIR for RSS indirection table. For that we've added one direct TIR
per RQ, e.g.: TIR[i] -> RQ[i] (core i).
Publicize Modify flow rule destination and reveal it in flow steering API, to have the
ability to dynamically modify the destination TIR(core) for aRFS rules from the
ethernet driver.
Initializing CPU reverse mapping to notify upper layer on internal receive queue cpu
mappings.
Some design refactoring for mlx5e ethernet driver flow tables and flow steering API.
Now the caller of create_flow_table can choose the level of the flow table, this way
we will create the mlx5e flow tables in a reversed order and connect them as we go,
we create flow table[i+1] before flow table[i] to be able to set flow table[i + 1] as
a destination of flow table[i] once flow table[i] is created.
also we have split the main flow table in the following manner:
- From before: RX packet had to visit two flow tables until it is delivered to its receive queue:
RX packet -> vlan filter flow table -> main flow table.
> vlan filter will check the packet vlan field is allowed.
> main flow will check if the dest mac is allowed and will check the l3/l4 headers to
retrieve the RSS hash for steering the packet into its final receive queue.
- Now main flow table is split into l2 dst mac steering table and ttc (traffic type classifier) table:
RX packet -> vlan filter -> l2 table -> ttc table
> vlan filter - same as before
> L2 filter - filter packets according their destination mac address
> ttc table - classify packet headers for RSS steering
- L3/L4 classification rules to steer the packet according to thier headers hash
- in case of none of the rules applies the packet is steered to RQ[0]
After the above refactoring all left to-do is to create aRFS flow table which will manage
aRFS steering rules to forward traffic to the desired RQ (core) and just connect the ttc
table rules destinations to aRFS flow table.
aRFS flow table in case of a miss will deliver the traffic to the core where the original
ttc hash would have chosen.
TTC table is not initialized and enabled until the user explicitly asks to, i.e. setting the NETIF_F_NTUPLE
to ON. This way there is no need for ttc table to forward traffic to aRFS table unless required.
When setting back to OFF aRFS flow table is disabled and disconnected.

Accelerated RFS requires that ntuple filtering is enabled via
ethtool and driver supports ndo_rx_flow_steer.
When the ntuple filtering is enabled, we modify the l3_l4 ttc
rules to point on the aRFS flow tables and when the filtering
is disabled, we modify the l3_l4 ttc rules to point on the RSS
TIRs.
