Resume device before calling napi_schedule, instead of doing in the napi
poll routine. Polling is done in softrq context. We can't call the PM
resume logic from there as it's blocking and not irq safe.
In order to make it work modify the interrupt handler to be run from irq
handler thread.

The probe() function is only used for the DP83822 PHY, leaving the
private data pointer uninitialized for the smaller DP83825/26 models.
While all uses of the private data structure are hidden in 82822 specific
callbacks, configuring the interrupt is shared across all models.
This causes a NULL pointer dereference on the smaller PHYs as it accesses
the private data unchecked. Verifying the pointer avoids that.

Recent sfc NICs are TSO capable for some tunnel protocols. However, it
was not working properly because the feature was not advertised in
hw_enc_features, but in hw_features only.
Setting up a GENEVE tunnel and using iperf3 to send IPv4 and IPv6 traffic
to the tunnel show, with tcpdump, that the IPv4 packets still had ~64k
size but the IPv6 ones had only ~1500 bytes (they had been segmented by
software, not offloaded). With this patch segmentation is offloaded as
expected and the traffic is correctly received at the other end.

Make sure that xdp_do_flush() is always executed before
napi_complete_done(). This is important for two reasons. First, a
redirect to an XSKMAP assumes that a call to xdp_do_redirect() from
napi context X on CPU Y will be followed by a xdp_do_flush() from the
same napi context and CPU. This is not guaranteed if the
napi_complete_done() is executed before xdp_do_flush(), as it tells
the napi logic that it is fine to schedule napi context X on another
CPU. Details from a production system triggering this bug using the
veth driver can be found following the first link below.
The second reason is that the XDP_REDIRECT logic in itself relies on
being inside a single NAPI instance through to the xdp_do_flush() call
for RCU protection of all in-kernel data structures. Details can be
found in the second link below.

Commit 1d18bb1a4ddd ("devlink: allow registering parameters after
the instance") as the subject implies introduced possibility to register
devlink params even for already registered devlink instance. This is a
bit problematic, as the consistency or params list was originally
secured by the fact it is static during devlink lifetime. So in order to
protect the params list, take devlink instance lock during the params
operations. Introduce unlocked function variants and use them in drivers
in locked context. Put lock assertions to appropriate places.

Stop assuming the IPA packet status has a fixed format (defined by
a C structure). Instead, use a function to extract each field from
a block of data interpreted as an IPA packet status. Define an
enumerated type that identifies the fields that can be extracted.
The current function extracts fields based on the existing
ipa_status structure format (which is no longer used).
Define IPA_STATUS_RULE_MISS, to replace the calls to field_max() to
represent that condition; those depended on the knowing the width of
a filter or router rule in the IPA packet status structure.

The next patch reworks how the IPA packet status structure is
interpreted. This patch does some preparatory work, to make it
easier to see the effect of that change:
- Change a few functions that access fields in a IPA packet status
structure to store field values in local variables with names
related to the field.
- Pass a void pointer rather than an (equivalent) status pointer
to two functions called by ipa_endpoint_status_parse().
- Use "rule" rather than "val" as the name of a variable that
holds a routing rule ID.
- Consistently use "IPA packet status" rather than "status
element" when referring to this data structure.

The packet length encoded in an IPA packet status buffer is computed
more than once in ipa_endpoint_status_parse(). It is also checked
again in ipa_endpoint_status_skip(), which that function calls.
Compute the length once, and use that computed value later rather
than recomputing it. Check for it being zero in the parse function
rather than in ipa_endpoint_status_skip().

The build system currently complains:
scripts/Makefile.build:252: drivers/net/dsa/ocelot/Makefile:
felix.o is added to multiple modules: mscc_felix mscc_seville
Since felix.c holds the DSA glue layer, create a mscc_felix_dsa_lib.ko.
This is similar to how mscc_ocelot_switch_lib.ko holds a library for
configuring the hardware.

virtchnl: update and refactor
Jesse Brandeburg says:
The virtchnl.h file is used by i40e/ice physical function (PF) drivers
and irdma when talking to the iavf driver. This series cleans up the
header file by removing unused elements, adding/cleaning some comments,
fixing the data structures so they are explicitly defined, including
padding, and finally does a long overdue rename of the IWARP members in
the structures to RDMA, since the ice driver and it's associated Intel
Ethernet E800 series adapters support both RDMA and IWARP.
The whole series should result in no functional change, but hopefully
clearer code.

virtchnl: i40e/iavf: rename iwarp to rdma
virtchnl: do structure hardening
virtchnl: update header and increase header clarity
virtchnl: remove unused structure declaration

Almost all validation logic is in the drivers, but they are
missing reliable way to convey failure reason to userspace
applications.
Let's use extack to return this information to users.

CONFIG_ETHTOOL_NETLINK=n
ethtool_aggregate_*_stats() are implemented in net/ethtool/stats.c, a
file which is compiled out when CONFIG_ETHTOOL_NETLINK=n. In order to
avoid adding Kbuild dependencies from drivers (which call these helpers)
on CONFIG_ETHTOOL_NETLINK, let's add some shim definitions which simply
make the helpers dead code.
This means the function prototypes should have been located in
include/linux/ethtool_netlink.h rather than include/linux/ethtool.h.
Fixes: 449c5459641a ("net: ethtool: add helpers for aggregate statistics")
