When the sunvnet_common code was split out for use by both sunvnet
and the newer ldmvsw, it was made into a static kernel library, which
limits the usefulness of sunvnet and ldmvsw as loadables, since most
of the real work is being done in the shared code. Also, this is
simply dead code in kernels that aren't running the LDoms.
This patch makes the sunvnet_common into a dynamically loadable
module and makes sunvnet and ldmvsw dependent on sunvnet_common.

sfc: prevent bogus interrupt-mode fallbacks
EF10 VFs only support MSI-X interrupts, not MSI or legacy. This series
stops the probe logic from trying to fallback to those if MSI-X interrupt
probe fails. It also prevents selecting them with the interrupt_mode
module parameter.
This avoids producing messages like "failed to hook legacy IRQ 0" and "IRQ
handler type mismatch for IRQ 0", and ensures that the relevant error
(from the attempt to enable MSI-X) is reported to the caller.

bridge: minor fdb cleanup

We can simplify the logic of entries pointing to the bridge by
converging the fdb_delete_by functions, this would allow us to use the
same function for both cases since the fdb's dst is set to NULL if it is
pointing to the bridge thus we can always check for a port match.

40GbE Intel Wired LAN Driver Updates 2017-02-11
This series contains updates to i40e and i40evf only.
Jake makes a minor change to prevent a minor bit of work, if it is not
necessary. In the case where we do not have a client, there is no need
to check the client params, so move the check till after we have ensured
we have a client. Correct a code comment which incorrectly implied
that raw_packet buffers were freed in i40e_clean_tx_ring(), so fixed
the code comment to better explain where memory is freed. Reduce the
severity and frequency of the message notifying we cleared the receive
timestamp register, since the logic has a much better detection scheme
that could detect a stalled receive timestamp register. The improved
logic was actually causing the notification message to occur more
frequently and was giving the user a false perception that a timestamp
event was missed for a valid packet, so reduce the severity from
dev_warn to dev_dbg and only fire off the message when 3 or 4 of the
RXTIME registers are stalled and get cleared within the same
watchdog event. Fixed a bug, where we were modifying the mac_filter
outside a lock when handling the addition of broadcast filters. Fix
this by updating i40e_update_filter_state logic so that it knows to
avoid broadcast filters, which ensures that we do not have to remove
the filter separately and can put it back using the normal flow.
Refactored how we add new filters to firmware to avoid a race condition
that can occur due to removing filters from the hash temporarily.
Mitch adds a sleep (without timeout) so that we wait for a reply from
the PF before we continue, since the iWarp client cannot continue until
the operation is completed. Fixed up a function which could never
return an error, to be void and cleaned up the checking of the now
null and void return value.
Scott limits the DMA sync to CPU to the actual length of the incoming
packet, versus the syncing of the entire buffer. Also reduces the
receive buffer struct (by a single pointer) and align the driver to be
more consistent with other Intel drivers with respect to packets that
span buffers.
Sudheer adds a field to track the bus number info and modified log
statements to print bus, device and function information.
Henry adds the ability to store the FEC status bits from the link up
event. Also adds the ethtool support for FEC capabilities and 25G
link types.

mv88e6xxx Watchdog support
The Marvell switches have an in built watchdog over some of the
internal state machine. The watchdog can be configured to raise an
interrupt on error. The problem the watchdog found is then logged to
the kernel log.
The older switches can automagically perform a software reset when the
watchdog triggers. This just resets the internal state machine, but
leaves the switch configuration unchanged.
The 6390 family of switches cannot both raise an interrupt and
automagically perform a software reset. So the interrupt handler has
to perform the switch reset, and then re-enable the watchdog
interrupts.
This has been tested using hacked together debugfs code which allows
the "force" bit to be set, so cause a watchdog interrupt.

The switch contains a watchdog looking for issues with the internal
gubbins of the switch. Hook the interrupt the watchdog triggers and
log the value of the control register indicating why the watchdog
fired. The watchdog can only be cleared with a switch reset, which
will destroy the current configuration. Rather than doing this, just
disable the interrupt.
The mv88e6390 family has different watchdog registers. So use an ops
structure, so support for the mv88e6390 family can be added later.

This patch allows userspace to specify the generation ID that has been
used to build an incremental batch update.
If userspace specifies the generation ID in the batch message as
attribute, then nfnetlink compares it to the current generation ID so
you make sure that you work against the right baseline. Otherwise, bail
out with ERESTART so userspace knows that its changeset is stale and
needs to respin. Userspace can do this transparently at the cost of
taking slightly more time to refresh caches and rework the changeset.
This check is optional, if there is no NFNL_BATCH_GENID attribute in the
batch begin message, then no check is performed.
