The pm_rumtime work queue is causing the device to be suspended during
initialisation, thus the initialisation may not be able to access registers
properly. As the code is called from a work queue, it is possible that this
is not seen from certain configurations/builds due to the asynchronos
nature of the code.

Another issue has also been found where the network device registration
calls back into the driver thus causing further pm_runtime calls that
also caused issues with the MDIO bus code. This has now been checked
and is the only place the MDIO can be called without the device open.

Use pm_runtime_get_sync() and pm_runtime_put() to ensure that the
pm system does not suspend it during the probe() call and remove the
now unnecessary pm_runtime_resume() call. Also add a call in the error
path to call pm_runtime_disable().

This fixes the external abort that can cause /sbin/init or other such
init processed to die.

tipc: fix handling of NETDEV_CHANGEADDR event

Aside from manual reconfiguration of the netdevice hwaddr, this can also
be changed automatically for an interface bond in active-backup mode
if fail_over_mac is enabled. This patchset fixes the handling of this
event in TIPC by properly updating the l2 media address for the bearer,
followed by a reinitialization of the node discovery mechanism.
====================
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

The node discovery domain is assigned when a bearer is enabled.
In the previous commit we reflect this attribute directly in the
bearer structure since it's needed to reinitialize the node
discovery mechanism after a hardware address change.

There's no need to replicate this attribute anywhere else, so we
remove it from the tipc_link_req structure.

If the hardware address of a underlying netdevice is changed, it is
not enough to simply reset the bearer/links over this device. We
also need to reflect this change in the TIPC bearer and node
discovery structures aswell.

This patch adds the necessary reinitialization of the node disovery
mechanism following a hardware address change so that the correct
originating media address is advertised in the discovery messages.

Intel Wired LAN Driver Updates

This series contains updates to e1000e, igb, i40e and i40evf

Anjali provides i40e fix to remove the ATR filter on RST as well as FIN
packets.  Cleans up add_del_fdir() because it was used and implemented
only for the add, so change the name and drop a parameter.  Adds the
ability to drop a flow if we wanted to and adds a flow director
message level to be used for flow director specific messages.

Mitch fixes an issue on i40evf where the Tx watchdog handler was causing
an oops when sending an admin queue message to request a reset because
the admin queue functions use spinlocks.

Greg provides a change to i40e to make the alloc and free queue vector
calls orthogonal.

Shannon fixes i40e to verify the eeprom checksum and firmware CRC status
bits, and shutdown the driver if they fail.  This change stops the
processing of traffic, but does not kill the PF netdev so that the
NVMUpdate process still has a chance at fixing the image.  Also provides
a fix to make sure the VSI has a netdev before trying to use it in
the debugfs netdev_ops commands.

Jakub Kicinski provides patches for e1000e and igb to fix a number issues
found in the PTP code.

be2net: add vxlan offload support

The first patch adds the FW cmds needed to configure the Skyhawk-R
chip for supporting VxLAN offloads. The second patch implements the
ndo_add/del_vxlan_port() methods and the plumbing for supporting
RX/TX csum, TSO and RSS steering offloads for VxLAN traffic.

v2 changes:
NETIF_F_SG need not be set for hw_enc_features by the driver as it is
done by the stack.

v3 changes:
* Defer FW cmds needed for VxLAN offloads to a workqueue
* Reset FW to VxLAN offloads disabled state in the unload path

v4 changes:
* Revert the usage of workqueue (introduced in v3) to implement
ndo_add/del_vxlan_port() as it is currently not needed (none of the
FW cmd calls sleep.) Suggested by David M.

   This patch re-factors the be_set_profile_config() code (used so far
   only for setting VF QoS) to be used to set any type of descriptor.
2) The MANAGE_IFACE_FILTERS cmds is needed to convert a normal interface
