qed/qede: Mostly-cleanup series
This series contains some cleanup of the qed and qede code:
- #1 contains mostly static/endian changes in order to allow qede to
pass sparse compilation cleanly.
- #2, #5 and #6 are either semantic or remove dead-code from driver.
- #9, #10 and #11 relate to printing and slightly change some APIs
between qed and the protocol drivers for that end [sharing the
interface names and information regarding device].
The rest of the patches are minor changes/fixes to various flows
in qed.

Today, driver has a synchronization point while closing
the device which synchronizes its slowpath interrupt line.
However, that's insufficient as that ISR would schedule the

By doing a disable/enable on the taskelt we guarantee that all

Vivien Didelot says:
====================
net: dsa: distribute switch events
DSA is by nature the support for a switch fabric, which can be composed
of a single, or multiple interconnected Ethernet switch chips.
The current DSA core behavior is to identify the slave port targeted by
a request (e.g. adding a VLAN entry), and program the switch chip to
which it belongs accordingly.
This is problematic in a multi-chip environment, since all chips of a
fabric must be aware of most configuration changes. Here are some
concrete examples in a 3-chip environment:
[CPU].................... (mdio)
(eth0) | : : :
_|_____ _______ _______
[__sw0__]--[__sw1__]--[__sw2__]
| | | | | | | | |
v v v v v v v v v
p1 p2 p3 p4 p5 p6 p7 p8 p9
If you add a VLAN entry on p7, sw2 gets programmed, but frames won't
reach the CPU interface in a VLAN filtered setup. sw0 and sw1 also need
to be programmed. The same problem comes with MAC addresses (FDB, MDB),
or ageing time changes for instance.
This patch series uses the notification chain introduced for bridging,
to notify not only bridge, but switchdev attributes and objects events
to all switch chips of the fabric.
An ugly debug message printing the ignored event and switch info in the
code handling the switch VLAN events would give us:
# bridge vlan add dev p7 vid 42
sw0: ignoring DSA_NOTIFIER_VLAN_ADD for sw2 (prepare phase)
sw1: ignoring DSA_NOTIFIER_VLAN_ADD for sw2 (prepare phase)
sw0: ignoring DSA_NOTIFIER_VLAN_ADD for sw2 (commit phase)
sw1: ignoring DSA_NOTIFIER_VLAN_ADD for sw2 (commit phase)
To achieve that, patches 1-8 change the scope of the bridge and
switchdev callbacks from the DSA slave device to the generic DSA port,
so that the port-wide API can be used later for switch ports not exposed
to userspace, such as CPU and DSA links.
Patches 9-15 move the DSA port specific functions in a new port.c file.
Patches 16-20 introduce new events to notify the fabric about switchdev
attributes and objects manipulation.
This patch series only adds the plumbing to support a distributed
configuration, but for the moment, each switch chip ignores events from
other chips of the fabric, to keep the current behavior.
The next patch series will add support for cross-chip configuration of
bridge ageing time, VLAN and MAC address databases operations, etc.

Move them from the public net/dsa.h file to the private dsa_priv.h file.
Also use this opportunity to turn the events into an anonymous enum,
because we don't care about the values, and this will prevent future

Pull networking fixes from David Miller:
"Mostly netfilter bug fixes in here, but we have some bits elsewhere as
well.
1) Don't do SNAT replies for non-NATed connections in IPVS, from
Julian Anastasov.
2) Don't delete conntrack helpers while they are still in use, from
Liping Zhang.
3) Fix zero padding in xtables's xt_data_to_user(), from Willem de
Bruijn.
4) Add proper RCU protection to nf_tables_dump_set() because we
cannot guarantee that we hold the NFNL_SUBSYS_NFTABLES lock. From
Liping Zhang.
5) Initialize rcv_mss in tcp_disconnect(), from Wei Wang.
6) smsc95xx devices can't handle IPV6 checksums fully, so don't
advertise support for offloading them. From Nisar Sayed.
7) Fix out-of-bounds access in __ip6_append_data(), from Eric
Dumazet.
8) Make atl2_probe() propagate the error code properly on failures,
from Alexey Khoroshilov.
9) arp_target[] in bond_check_params() is used uninitialized. This
got changes from a global static to a local variable, which is how
this mistake happened. Fix from Jarod Wilson.
10) Fix fallout from unnecessary NULL check removal in cls_matchall,
from Jiri Pirko. This is definitely brown paper bag territory..."

nfp: introduce nfp_port and nfp_app
This series builds foundation for upcoming development. So far the nfp
driver was focused on delivering basic NIC-like functionality. We want
to switch gears a bit going forward and support more advanced applications.
First few patches are naming clean ups and reshuffling. The two main
structures this series adds are nfp_port and nfp_app.
nfp_port represents a device port, where port can mean external port,
VF or PF. For now only external port/MAC/PHY port is added. nfp_port
is supposed to make it easy to share ethtool and devlink code regardless
of netdev type (full vNIC vs representors).
nfp_app is an abstraction which should allow easier development of new
applications. So far we have relied fully on port capabilities to detect
which offloads and features are available. The usual development model
for NFP is that people start with one of our "core NIC" FW apps (C one,
or a macro assembler one) and build advanced functionality on top of that.
Therefore basic netdev code is shared, but the higher-level logic is
usually more project specific. The higher-level logic is also per-adapter
rather than per-port, so creating per-adapter control entity makes sense.
Hopefully the separation of lower-level netdev code and application logic
will help us limit interdependencies and accelerate parallel projects
(e.g. TC flower offloads vs eBPF offload).
v2:
- don't hide definition of nfp_app to avoid silly function calls (Dave);
- reorder kdoc of nfp_main (Simon);
- make nfp_netdev_is_nfp_net() static inline as well.

State of autonegotiation may have changed but is not yet refreshed.
Make sure ethtool respects the NFP_PORT_CHANGED flag when looking
at autoneg.

If reading new state of the port failed, mark the port back as CHANGED.
This way next user state request will trigger refresh, which will
hopefully succeed.
