struct ice_vsi has two fields, state and flags which seem to

'state'.
enum ice_state is used to represent state information of the PF.
While some of these enum values can be use to represent VSI state,
it makes more sense to represent VSI state with its own enum. So
derive a new enum ice_vsi_state from ice_vsi_flags and ice_state

Once a netdev is registered, the corresponding network interface can
be immediately used by userspace utilities (like say NetworkManager).
This can be problematic if the driver technically isn't fully up yet.
Move netdev registration to the end of probe, as by this time the
driver data structures and device will be initialized as expected.
However, delaying netdev registration causes a failure in the aRFS flow

not clear why this check was added to begin with, so remove it.

ethtool: support FEC configuration over netlink
This series adds support for the equivalents of ETHTOOL_GFECPARAM
and ETHTOOL_SFECPARAM over netlink.
As a reminder - this is an API which allows user to query current
FEC mode, as well as set FEC manually if autoneg is disabled.
It does not configure anything if autoneg is enabled (that said
few/no drivers currently reject .set_fecparam calls while autoneg
is disabled, hopefully FW will just ignore the settings).
The existing functionality is mostly preserved in the new API.
The ioctl interface uses a set of flags, and link modes to tell
user which modes are supported. Here is how the flags translate
to the new interface (skipping descriptions for actual FEC modes):
ioctl flag | description | new API
================================================================
ETHTOOL_FEC_OFF | disabled (supported) | \
ETHTOOL_FEC_RS | | ` link mode bitset
ETHTOOL_FEC_BASER | | / .._A_FEC_MODES
ETHTOOL_FEC_LLRS | | /
ETHTOOL_FEC_AUTO | pick based on cable | bool .._A_FEC_AUTO
ETHTOOL_FEC_NONE | not supported | no bit, no AUTO reported
Since link modes are already depended on (although somewhat implicitly)
for expressing supported modes - the new interface uses them for
the manual configuration, as well as uses link mode bit number
to communicate the active mode.
Use of link modes allows us to define any number of FEC modes we want,
and reuse the strset we already have defined.
Separating AUTO as its own attribute is the biggest changed compared
to the ioctl. It means drivers can no longer report AUTO as the
active FEC mode because there is no link mode for AUTO.
active_fec == AUTO makes little sense in the first place IMHO,
active_fec should be the actual mode, so hopefully this is fine.
The other minor departure is that None is no longer explicitly
expressed in the API. But drivers are reasonable in handling of
this somewhat pointless bit, so I'm not expecting any issues there.
One extension which could be considered would be moving active FEC
to ETHTOOL_MSG_LINKMODE_*, but then why not move all of FEC into
link modes? I don't know where to draw the line.
netdevsim support and a simple self test are included.
Next step is adding stats similar to the ones added for pause.

modes are supported. Take this further an use link modes for
manual configuration. Old struct ethtool_fecparam is still

and forth. We can revisit the internal API if number of FEC
encodings starts to grow.
Enforce only one active FEC bit (by using a bit position

When cleared, the 'force' parameter in nexthop bucket replacement
notifications indicates that a driver should try to perform an atomic
replacement. Meaning, only update the contents of the bucket if it is
inactive.
Since mlxsw only queries buckets' activity once every second, there is
no point in trying an atomic replacement if the idle timer interval is
smaller than 1 second.
Currently, mlxsw ignores the original value of 'force' and will always
try an atomic replacement if the idle timer is not smaller than 1
second.
Fix this by taking the original value of 'force' into account and never
promoting a non-atomic replacement to an atomic one.

====================
MPTCP: Allow initial subflow to be disconnected
An MPTCP connection is aggregated from multiple TCP subflows, and can
involve multiple IP addresses on either peer. The addresses used in the
initial subflow connection are assigned address id 0 on each side of the
link. More addresses can be added and shared with the peer using address
IDs of 1 or larger. MPTCP in Linux shares non-zero address IDs across
all MPTCP connections in a net namespace, which allows userspace to
manage subflow connections across a number of sockets. However, this
makes the address with id 0 a special case, since the IP address
associated with id 0 is potentially different for each socket.
This patch set allows the initial subflow to be disconnected when
userspace specifies an address to remove using both id 0 and an IP
address, or when the peer sends an RM_ADDR for id 0.
Patches 1 and 3 implement the change for requests from the peer and
userspace, respectively.
Patch 2 consolidates some code for disconnecting subflows.
Patches 4-6 update the self tests to cover removal of subflows using
address id 0.

IDs are supposed to be between 0 and 255.
In pm_nl_ctl, for both the 'add' and 'get' instruction, the ID is casted
in a u_int8_t. So if we give 256, we will delete ID 0. Obviously, the
goal is not to delete this ID by giving 256.
We could modify pm_nl_ctl and stop if the ID is negative or higher than
255 but probably better not to increase the number of lines for such
things in this tool which is only used in selftests. Instead, we use it
within the limits.
This modification also means that we will no longer add a new ID for the
2nd entry. That's why we removed an expected entry from the dump and
introduced with
commit dc8eb10e95 ("selftests: mptcp: add testcases for setting the address ID").
So now we delete ID 9 like before and we add entries for IDs 10 to 255
that are deleted just after.
Note that this could be seen as a fix but it was not really an issue so
far: we were simply playing with ID 0/1 once again. With the following
commit ("selftests: mptcp: add addr argument for del_addr"), it will be
different because ID 0 is going to required an address. We don't want
errors when trying to delete ID 0 without the address argument.
