This small batch contains several Netfilter fixes for your net-next
tree, more specifically:

* Fix compilation warning in nft_ct in NF_CONNTRACK_MARK is not set,
  from Kristian Evensen.

* Add dependency to IPV6 for NF_TABLES_INET. This one has been reported
  by the several robots that are testing .config combinations, from Paul
  Gortmaker.

* Fix default base chain policy setting in nf_tables, from myself.

not initialized yet. This might cause confusion for the people who use
NEIGH_VAR_SET in ndo_neigh_setup. So rather introduce NEIGH_VAR_INIT for

Intel Wired LAN Driver Updates

This series contains several updates from Alex to ixgbe.

To avoid head of line blocking in the event a VF stops cleaning Rx descriptors
he makes sure QDE bits are set for a VF before the Rx queues are enabled.

To avoid a situation where the head write-back registers can remain set ofter
the driver is unloaded he clears them on a VF reset.

Alexander Duyck (2):
  ixgbe: Force QDE via PFQDE for VFs during reset
  ixgbe: Clear head write-back registers on VF reset
====================
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

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: add IFA_F_NOPREFIXROUTE flag to suppress creation of IP6 routes

v1 -> v2: add a second commit, handling NOPREFIXROUTE in ip6_del_addr.
v2 -> v3: reword commit messages, code comments and some refactoring.
v3 -> v4: refactor, rename variables, add enum
v4 -> v5: rebase, so that patch applies cleanly to current net-next/master
====================
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

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.

When adding/modifying an IPv6 address, the userspace application needs
a way to suppress adding a prefix route. This is for example relevant
together with IFA_F_MANAGERTEMPADDR, where userspace creates autoconf
generated addresses, but depending on on-link, no route for the
prefix should be added.

An earlier commit (f25b119c "Fix error messages while driver load for VFs")
incorrectly set the adapter->cmd_privileges value for VFs (in a
multi-channel config) to MAX_PRIVILEGES. This causes FW cmd failures
and avoidable error logs when certian cmds are issued by a VF.
Also, move the multi-channel hack to be_cmds.c inside
be_cmd_get_fn_privileges() routine.

Fix this by adding netdev_adjacent_rename_links(dev, oldname) which renames

We don't need a rollback because only we control these symlinks and if we
