====================
nf_tables updates for net-next
The following patchset contains the following nf_tables updates,
mostly updates from Patrick McHardy, they are:
* Add the "inet" table and filter chain type for this new netfilter
family: NFPROTO_INET. This special table/chain allows IPv4 and IPv6
rules, this should help to simplify the burden in the administration
of dual stack firewalls. This also includes several patches to prepare
the infrastructure for this new table and a new meta extension to
match the layer 3 and 4 protocol numbers, from Patrick McHardy.
* Load both IPv4 and IPv6 conntrack modules in nft_ct if the rule is used
in NFPROTO_INET, as we don't certainly know which one would be used,
also from Patrick McHardy.
* Do not allow to delete a table that contains sets, otherwise these
sets become orphan, from Patrick McHardy.
* Hold a reference to the corresponding nf_tables family module when
creating a table of that family type, to avoid the module deletion
when in use, from Patrick McHardy.
* Update chain counters before setting the chain policy to ensure that
we don't leave the chain in inconsistent state in case of errors (aka.
restore chain atomicity). This also fixes a possible leak if it fails
to allocate the chain counters if no counters are passed to be restored,
from Patrick McHardy.
* Don't check for overflows in the table counter if we are just renaming
a chain, from Patrick McHardy.
* Replay the netlink request after dropping the nfnl lock to load the
module that supports provides a chain type, from Patrick.
* Fix chain type module references, from Patrick.
* Several cleanups, function renames, constification and code
refactorizations also from Patrick McHardy.
* Add support to set the connmark, this can be used to set it based on
the meta mark (similar feature to -j CONNMARK --restore), from
Kristian Evensen.
* A couple of fixes to the recently added meta/set support and nft_reject,
and fix missing chain type unregistration if we fail to register our
the family table/filter chain type, from myself.

Introduce an xtables add-on for matching L2TP packets. Supports L2TPv2
and L2TPv3 over IPv4 and IPv6. As well as filtering on L2TP tunnel-id
and session-id, the filtering decision can also include the L2TP
packet type (control or data), protocol version (2 or 3) and
encapsulation type (UDP or IP).
The most common use for this will likely be to filter L2TP data
packets of individual L2TP tunnels or sessions. While a u32 match can
be used, the L2TP protocol headers are such that field offsets differ
depending on bits set in the header, making rules for matching generic
L2TP connections cumbersome. This match extension takes care of all
that.

Intel Wired LAN Driver Updates
This series contains updates to i40e only.
Anjali provides a fix where interrupts were not being re-enabled on ICR0
even though they were auto masked by hardware. Then provides a fix to
cleanup RSS initialization because it was doing some extra work, so
remove the extra work and any bugs it created when managing number of
queues. Since hardware requires a full packet template to be pointed to
when adding hardware flow filters, add the template and use it for
programming filters.
Jesse provides a fix to replace the use of driver specific defines with
kernel ETH_ALEN defines. Then disables packet split because with the
use of GRO, we do not need the extra bus overhead. Fixes spelling
error in code comment.
Kamil provides a fix for the driver where the hardware expects the MAC
address in a very specific format and the driver was filing the data
incorrectly.
Mitch provides a fix to resolve a panic on reset by adding checks to
VSI->rx_rings. Then shortens alloc_rx_buff_failed and
alloc_rx_page_failed variables since both part of an RX specific
structure so just remove the _rx part of the name. Then fixes
badly formatted lines, long lines and mis-formatted lines.
Shannon provides a fix to call AQ to release any reservation held by this
PF on the NVM resource lock on startup, in order to clear anything that
might have been left over from a previous run. Then removes interrupt on
AQ error since nearly everything we do is synchronous, using the
interrupt-on-error bit is unnecessary and causing unneeded interrupts.
Adds code to handle the ability to send messages among the physical
function interfaces by the admin queue.
Catherine sets the MFP flag earlier in software init and uses that flag
to decide if other hardware work-arounds are required which turns
off flow director in MFP mode.

The chain type module reference handling makes no sense at all: we take
a reference immediately when the module is registered, preventing the
module from ever being unloaded.
Fix by taking a reference when we're actually creating a chain of the
chain type and release the reference when destroying the chain.

This patch adds kernel support for setting properties of tracked
connections. Currently, only connmark is supported. One use-case
for this feature is to provide the same functionality as
-j CONNMARK --save-mark in iptables.
