For those supporting it, the number of bits used to mask the destination
port may vary. 6352 and such use 4-bit, while 6390 use 5-bit. Thus add a

====================
nfp: XDP adjust head support
This series adds support for XDP adjust head. Bulk of the code
is actually just paying technical debt. On reconfiguration request
nfp was allocating new resources separately leaving device running
with the existing set of rings. We used to manage the new resources
in special ring set structures. This set is simply separating the
datapath part of the device structure from the control information
allowing the new datapath structure to be allocated with all new
memory and rings. The swap operation is now greatly simplified.
We also save a lot of parameter passing this way. Hopefully the churn
is worth the negative diffstat.
Support for XDP adjust head is done in a pretty standard way. NFP
is a bit special because it prepends metadata before packet data
so we have to do a bit of memcpying in case XDP will run. We also
luck out a little bit because the fact that we already have prepend
space allocated means that one byte is enough to store the extra XDP
space (256 of standard prepend space is a bit inconvenient since
it would normally require 16bits or boolean with additional shifts).

ethernet QOS IP core. The binding that it uses is slightly different

Patch 2/7, 4/7, 5/7, 6/7 are to implement the process of asoc reset request,
add streams requests and all kinds of responses.
Patch 1/7 and 3/7 are ahead of 2/7 and 4/7 to add two event notification

Patch 7/7 is the last patch for implementing rfc6525 sctp stream reconf
to add sysctl and sockopt interface for users to enable sctp stream reconf.
After this patchset, sctp stream reconf will be able to work as rfc6525.

- rename the titles of the commits and improve some changelogs.
- improve sctp_chunk_lookup_strreset_param and reuse it in patch 4/7.
- process addstrm outreq as the ack of in addstrm inreq if strreset_chunk

- remove the stream alloc when sending addstrm inreq, and the process in

net: ipv6: Add early demux handler for UDP unicast
While running a single stream UDPv6 test, we observed that amount
of CPU spent in NET_RX softirq was much greater than UDPv4 for an
equivalent receive rate. The test here was run on an ARM64 based
Android system. On further analysis with perf, we found that UDPv6
was spending significant time in the statistics netfilter targets
which did socket lookup per packet. These statistics rules perform
a lookup when there is no socket associated with the skb. Since
there are multiple instances of these rules based on UID, there
will be equal number of lookups per skb.
By introducing early demux for UDPv6, we avoid the redundant lookups.
This also helped to improve the performance (800Mbps -> 870Mbps) on a
CPU limited system in a single stream UDPv6 receive test with 1450
byte sized datagrams using iperf.

59cc1f61f0 ("net: sched: convert

This allows us for bringing more clarity and determinism into the dump by
making default pfifo qdiscs visible.
We're not turning this on by default though, at it was deemed [2] too
intrusive / unnecessary change of default behavior towards userspace.
Instead, TCA_DUMP_INVISIBLE netlink attribute is introduced, which allows
applications to request complete qdisc hierarchy dump, including the
ones that have always been implicit/invisible.
Singleton noop_qdisc stays invisible, as teaching the whole infrastructure
about singletons would require quite some surgery with very little gain
(seeing no qdisc or seeing noop qdisc in the dump is probably setting
the same user expectation).

In the initial implementation we associated the VR with a specific
protocol (e.g., IPv4) and an LPM tree. However, this isn't really
accurate, as the same VR can be used for both IPv4 and IPv6 traffic, by
binding a different LPM tree to a {VR, Proto} pair.

This is needed so that users will be able to program a default route
into the VRF's table, thereby preventing lookup from leaking to other
tables.
Audit the code paths to make sure we don't rely on the presence of a
nexthop netdev, as it doesn't exist for above mentioned route types.

mlxsw: spectrum: Associate PVID vPort with appropriate netdev
When a VLAN device is configured on top of a LAG device (f.e.,
bond0.10), a vPort is created on top of each of the LAG's slaves and its
'dev' pointer is set to the VLAN device.
This is in contrast to the implicit PVID vPort (representing 'bond0'),
whose 'dev' pointer keeps pointing to the port netdev itself (f.e.,
'sw1p1').
Make both cases consistent by setting their 'dev' pointer to the actual
netdev they represent. Either the LAG device itself (in the case of the
PVID vPort) or the VLAN device on top of it.
This will later allow us to more easily understand for which netdev we
should create the router interface (RIF) upon enslavement to a VRF
master.

Merge branch 'bonding-winter-cleanup'
Mahesh Bandewar says:
====================
bonding: winter cleanup
Few cleanup patches that I have accumulated over some time now.
(a) First two patches are basically to move the work-queue initialization
from every ndo_open / bond_open operation to once at the beginning while
port creation. Work-queue initialization is an unnecessary operation
for every 'ifup' operation. However we have some mode-specific work-queues
and mode can change anytime after port creation. So the second patch is
to ensure the correct work-handler is called based on the mode.
(b) Third patch is simple and straightforward that removes hard-coded value
that was added into the initial commit and replaces it with the default
value configured.
(c) The final patch in the series removes the unimplemented "port-moved" state
from the LACP state machine. This state is defined but never set so
removing from the state machine logic makes code little cleaner.
(d) Reduce scope of some global variables to local.
Note: None of these patches are making any functional changes.
