Add geneve Rx offload support for x550em_a.

The implementation follows the vxlan code with the lower 16 bits of
the VXLANCTRL register holding the UDP port for VXLAN and the upper
for Geneve.

Disabled NFS filters in the RFCTL register which allows us to simplify
the check for VXLAN and Geneve packets in ixgbe_rx_checksum().

Removed vxlan from the name of the callback functions and replaced it
with udp_tunnel which is more in line with the new API.

40GbE Intel Wired LAN Driver Updates 2016-08-19

This series contains updates to i40e and i40evf only.

Jake provides several patches, first just moves a function to co-locate
the two functions related to configuring RSS via the admin queue, which
should help in spotting bugs when comparing the two functions.  Fixed
an issue where commit e69ff813 ("i40e: rework the functions to
configure RSS with similar parameters") missed checking whether the seed
is NULL before using it and did not use the passed in *lut parameter.
Fixed an issue where a previous refactor missed i40e_vsi_config_rss()
and the values were being ignored, so checked for the fields and used
them instead of default values.  Lastly replaced calls to
create_singlethread_workqueue() with alloc_workqueue() to provide more
control over workqueue creation and allows explicit setting of the
desired mode of operation.

Mitch adds link speed to log messages and reports speed through ethtool.

Carolyn refactors tail bump check and fixes byte ordering problems found
when enabling this feature support.  Adds support for HMC resources and
profile commands for x722 firmware.

Heinrich Schuchardt fixes format identifiers from %u to %d since the
variable is defined as an integer.

Catherine fixes an issue where there was a race condition between the
completion of the client open and calls to the client ops, so ensured
that client ops are not called until we are sure client is open.

Harshitha makes sure that i40e_client_release() does not try to use
an adapter pointer which may not be initialized, so make sure it is.

Joe Perches fixes the use of the local macro XSTRINGIFY() to use
__stringify() instead.

Avinash corrects the mutex usage in client_subtask().  Fixed the RDMA
client to open again after reset since it is closed during a PF reset.

Jeff (me) clean up whitespace issues, where indentation was done
inconsistently and with spaces versus tabs.

The patch creates sample code exercising bpf_skb_{set,get}_tunnel_key,
and bpf_skb_{set,get}_tunnel_opt for GRE, VXLAN, and GENEVE.  A native
tunnel device is created in a namespace to interact with a lwtunnel
device out of the namespace, with metadata enabled.  The bpf_skb_set_*
program is attached to tc egress and bpf_skb_get_* is attached to egress
qdisc.  A ping between two tunnels is used to verify correctness and
the result of bpf_skb_get_* printed by bpf_trace_printk.

We've already set sk to sock->sk and dereferenced it, so if it's NULL
we would have crashed already. Moreover, if it was NULL we would have
crashed anyway when jumping to 'out' and trying to unlock the sock.
Furthermore, if we had assigned a different value to 'sk' we would
have been calling lock_sock() and release_sock() on different sockets.

My conclusion is that these two lines are complete nonsense and only
serve to confuse the reader.

This new firmware for the qed* adpaters fixes several issues:
 - Better blocking of malicious VFs.
 - After FLR, Tx-switching [internal routing] of packets might
   be incorrect.
 - Deletion of unicast MAC filters would sometime have side-effect
   of corrupting the MAC filters configred for a device.
It also contains fixes for future qed* drivers that *hopefully* would be
sent for review in the near future.

In addition, it would allow driver some new functionality, including:
 - Allowing PF/VF driver compaitibility with old drivers [running
   pre-8.10.5.0 firmware].
 - Better debug facilities.

This would also bump the qed* driver versions to 8.10.9.20.

transmit queue is actually enabled, which may not happen during the
configure phase eve if we waited for it.  Converts to using netdev_dbg()

interval, it implements the same mechanism as mv88e6xxx_update() uses.
So use it in mv88e6xx_wait().

The mv88e6xxx driver times out operations on the switch based on
looping until an elapsed wall clock time is reached. However, if
usleep_range() sleeps much longer than expected, it could timeout with
an error without actually checking to see if the devices has completed
the operation. So replace the elapsed time with a fixed upper bound on
the number of loops.

Testing on various switches has shown that switches takes either 0 or
1 iteration, so a maximum of 16 iterations is a safe limit.

====================
PHY Kconfig and Makefile cleanup

The Ethernet PHY directory has slowly been getting more entries.
Split the entries in the Makefile and Kconfig into MDIO bus drivers
and PHYs. Within these two groups, sort them. This should reduce merge
conflicts and aid finding what one searches for.

The Kconfig text contains redundant "Driver for" and "Support for"
which add little value, make the vendor less obvious, and defeat the
shortcut key in the menu. Remove such text.

Remove the redundant "Support for" and "Drivers for" from the Kconfig
short description. This makes the manufacture much more prominent in
the list and makes the shortcut keys useful.

Sort the files to reduce merge conflicts and to make it easier to find
drivers by name. Also separate the MDIO bus drivers from the PHY
drivers, again to help find what you need.
