net: bcmgenet: clear status to reduce spurious interrupts
Since the DMA interrupt status is latched and the DMA servicing can be
polled, it is a good idea to clear the latched status of a DMA interrupt
before performing the service that would be invoked by the interrupt.
This prevents old status from causing spurious interrupts when the
interrupt is unmasked at a later time.

gtp: misc improvements
This is a resent of last series that missed the merge window. There
are no changes compared to v4.
v4: Compared to v3 it contains mostly smallish naming and spelling fixes.
It also drops the documentation patch, Harald did a better job with the
documentation and the some things I described do not yet match the implementation.
I'll readd the relevant parts with a follow up series.
This series lays the groundwork for removing the socket references from
the GTP netdevice by removing duplicate code and simplifying the logic on
some code paths.
It slighly changes the GTP genl API by making the socket parameters optional
(though one of them is still required).
The removal of the socket references will break the 1:1 releation between
GTP netdevice and GTP socket that prevents us to support multiple VRFs with
overlapping IP addresse spaces attached to the same GTP-U entity (needed for
multi APN support, coming a follow up series).
Pablo found a socket hold problem in v2. In order to solve that I had to
switch the socket references from the struct socket to the internal
struct sock. This should have no functionl impact, but we can now hang
on to the reference without blocking user space from closing the GTP socket.
v4->v5:
* resent for new merge window
v3->v4:
* drop the documentation patch
* spelling fixes
* pass nlattr instead of genl_info into gtp_find_dev,
makes the code slightly more compact and readable

====================
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).

nfp: add support for xdp_adjust_head()
Support prepending data from XDP. We are already always allocating
some headroom because FW may prepend metadata to packets.
xdp_adjust_head() can be supported by making sure that headroom is
big enough for XDP. In case FW had prepended metadata to the packet,
however, we have to move it out of the way before we call XDP.

nfp: switch to using data path structures for reconfiguration
Instead of passing around sets of rings and their parameters just
store all information in the data path structure.
We will no longer user xchg() on XDP programs when we swap programs
while the traffic is guaranteed not to be flowing. This allows us
to simply assign the entire data path structures instead of copying
field by field.
The optimization to reallocate only the rings on the side (RX/TX)
which has been changed is also removed since it seems like it's not
worth the code complexity.

prepare mac operations for multiple queues
As agreed with David Miller, this patch-set is the first of 3 to enable

This first one concentrates on mac operations adding functionalities as:
a) Configuration through DT
b) RX and TX scheduling algorithms programming
b) TX queues weight programming (essential in weightes algorithms)
c) RX enable as DCB or AVB (preparing for future AVB support)

sctp: add receiver-side procedures for stream reconf asoc reset and add streams and response
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
for asoc reset and add streams.
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.
v1->v2:
- put these into a smaller group.
- 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
is not NULL in patch 4/7.
- remove the stream alloc when sending addstrm inreq, and the process in
peer will response it by sending a addstrm out request back in patch 5/7.
- adjust the process of addstrm in resp to fit in the codes that only alloc
streams through addstrm outreq in patch 6/7.
