ixgbe: Clear head write-back registers on VF reset
The Tx head write-back registers are not cleared during an FLR or VF reset.
As a result a configuration that had head write-back enabled can leave the
registers set after the driver is unloaded. If the next driver loaded doesn't
use the write-back registers this can lead to a bad configuration where
head write-back is enabled, but the driver didn't request it.
To avoid this situation the PF should be resetting the Tx head write-back
registers when the VF requests a reset.

ipv6 addrconf: don't cleanup prefix route for IFA_F_NOPREFIXROUTE
Refactor the deletion/update of prefix routes when removing an
address. Now also consider IFA_F_NOPREFIXROUTE and if there is an address
present with this flag, to not cleanup the route. Instead, assume
that userspace is taking care of this route.
Also perform the same cleanup, when userspace changes an existing address
to add NOPREFIXROUTE (to an address that didn't have this flag). This is
done because when the address was added, a prefix route was created for it.
Since the user now wants to handle this route by himself, we cleanup this
route.
This cleanup of the route is not totally robust. There is no guarantee,
that the route we are about to delete was really the one added by the
kernel. This behavior does not change by the patch, and in practice it
should work just fine.

net: vxlan: when lower dev unregisters remove vxlan dev as well
We can create a vxlan device with an explicit underlying carrier.
In that case, when the carrier link is being deleted from the
system (e.g. due to module unload) we should also clean up all
created vxlan devices on top of it since otherwise we're in an
inconsistent state in vxlan device. In that case, the user needs
to remove all such devices, while in case of other virtual devs
that sit on top of physical ones, it is usually the case that
these devices do unregister automatically as well and do not
leave the burden on the user.
This work is not necessary when vxlan device was not created with
a real underlying device, as connections can resume in that case
when driver is plugged again. But at least for the other cases,
we should go ahead and do the cleanup on removal.
We don't register the notifier during vxlan_newlink() here since
I consider this event rather rare, and therefore we should not
bloat vxlan's core structure unecessary. Also, we can simply make
use of unregister_netdevice_many() to batch that. fdb is flushed
upon ndo_stop().

====================
Intel Wired LAN Driver Updates, ixgbe: Add LER support
The following patches add Live Error Recovery (LER) support to the
ixgbe driver. This support also improves behavior in Thunderbolt
environments. This involves checking all register reads for a
value of all ones and when that is seen, to read the status
register, which should never properly return all ones, to
confirm whether the received value was correct. When this detects
a removal, the hw_addr field is cleared to indicate the removal.
This then blocks subsequent access to the device registers.
All register access macros have been changed to static inline
functions and all register accesses now use them.· Macro versions
are temporarily provided.
The __IXGBE_DOWN bit is no longer overloaded to also mean that
device removal has been initiated. Now the bit can be used to
protect ixgbe_down from multiple entry via test_and_set_bit. A
needed smp_mb__before_clear_bit was also added.
V2 Changes:
- Use ACCESS_ONCE where needed, thanks to Ben Hutchings
- Fix crash on module removal
- Use boolean values for boolean returns instead of 0 and 1
- Reword Kconfig help text
V3 Changes:
- Drop config option, per David Miller
- Drop tail register write checks, per Alexander Duyck
- Change writeq implementation to a static inline, thanks to Joe Perches
V4 Changes:
- Change __IXGBE_REMOVE to __IXGBE_REMOVING, per Scott Feldman's comment
- Add #define writeq writeq, per Alexander Duyck
- Change static inline functions to lower case, per David Miller
- Use new lower case names in added and modified register accesses
- Provide temporary upper case macros for register access functions
- Change IXGBE_REMOVED from macro to static inline and change references
- Correct IXGBE_WRITE_FLUSH to properly enclose parameter expansion

====================
atheros: modify statistics code
Following Ben Hutchings's advice on how to fill net_stats in alx [1],
this patch modifies the other atheros ethernet drivers
similarly. Minor whitespace/empty line changes in atl1c and atl1e to
make the code completely consistent between atl1c, atl1e, and alx.
I don't have this hardware, so these patches have only been
compile-tested.
v2 (changes only in atl1):
- don't set soft_stats.rx_missed_errors (Ben)
- add errors to soft_stats.{rx,tx}_packets (Ben)
- add soft_stats.rx_dropped field and update soft_stats.rx_dropped
instead of netdev->stats (overwritten) outside of the stats
update function
Detail of the changes (v1):
* atl1/atl1c/atl1e
- fix collisions computation
- rx_dropped = rx_rrd_ov
- rx_over_errors = 0
- rx_missed_errors = 0
- X_packets = X_ok + X_errors
* only atl1c/atl1e
- add rx_rxf_ov to rx_errors

Merge branch 'netdev_tracing'
Ben Hutchings says:
====================
Improve tracing at the driver/core boundary
These patches add static tracpeoints at the driver/core boundary which
record various skb fields likely to be useful for datapath debugging.
On the TX side the boundary is where the core calls ndo_start_xmit, and
on the RX side it is where any of the various exported receive functions
is called.
The set of skb fields is mostly based on what I thought would be
interesting for sfc.
These patches are basically the same as what I sent as an RFC in
November, but rebased. They now depend on 'net: core: explicitly select
a txq before doing l2 forwarding', so please merge net into net-next
before trying to apply them. The first patch fixes a code formatting
error left behind after that fix.

net: Add trace events for all receive entry points, exposing more skb fields
The existing net/netif_rx and net/netif_receive_skb trace events
provide little information about the skb, nor do they indicate how it
entered the stack.
Add trace events at entry of each of the exported functions, including
most fields that are likely to be interesting for debugging driver
datapath behaviour. Split netif_rx() and netif_receive_skb() so that
internal calls are not traced.
