The PF<->VF interface allows for the VF to request
multiple queues closure via a single message, but this has
never been used by any official driver.
We now deprecate this option, forcing each queue close
to arrive via a different command; This would be required
for future TLVs that are going to extend the queue TLVs with
additional information on a per-queue basis.

PF needs to validate the status of VF queues before asking firmware
to configure anything for them, but that validation is done in various
different forms - sometimes inadequate.
Add auxillary functions that can be used for testing of the queue
state and convert the various flows to use those instead of current
existing flows; Also, add missing validations where needed.

When starting the VF's vport, the PF would first configure
the status blocks of the VF and then reset them.
That would cause some of the configured information to be lost -
specifically it would mean that all the VFs queues would use
the Rx coalescing state-machine of the status block.

When PF responds to the VF requests it also cleans the HW-channel
indication in firmware to allow further VF messages to arrive,
but the order currently applied is wrong -
The PF is copying by DMAE the response the VF is polling on for
completion, and only afterwards sets the HW-channel to ready state.
This creates a race condition where the VF would be able to send
an additional message to the PF before the channel would get ready
again, causing the firmware to consider the VF as malicious.

When a VF is considered malicious, driver handling of the VF
FLR flow would clean said indication - but not if the FLR is
part of an sriov-disable flow.
That leads to further issues, as PF wouldn't re-enable the
previously malicious VF when sriov is re-enabled.
No reason for that - simply clean malicious indications in
the sriov-disable flow as well.

VFs are currently logging errors when communicating

Change to support host<->firmware command return value.
Fix for vf mac addr state command.
1. Added support for firmware commands to return a value:
- previously, the returned code overlapped with host codes, thus
commands were only returning 0 (success) or -1 (interpreted as
timeout)
- per 'response_manager.h', the error codes are split into two fields
(major/minor) now, firmware commands are grouped into their own
'major' group, separate from the host's 'major' group, which allow f/w
commands to return any 16-bit value
2. The command to set vf mac addr was logging a success message even if
command failed. Now command uses a callback function to log the status
message.
3. The command to set vf mac addr was not logging a message when set via
the host 'ip' command. Now, the callback function will log an
appropriate message.

When closing the ibmvnic device we need to release the resources used
in communicating to the virtual I/O server. These need to be
re-negotiated with the server at open time.
This patch moves the releasing of resources a separate routine
and updates the open and close handlers to release all resources at
close and re-negotiate and allocate these resources at open.

exceed the timeout, VNIC server will attempt to fail over. Since time
between probe and open of the device is indeterminate, move login and queue

__bcmgenet_tx_reclaim() is currently summing TX bytes/packets in a way
that is not SMP friendly, mutliples CPUs could run
__bcmgenet_tx_reclaim() independently and still update stats->tx_bytes
and stats->tx_packets, cloberring the other CPUs statistics.
Fix this by tracking per RX and TX rings the number of bytes, packets,
dropped and errors statistics, and provide a bcmgenet_get_stats()
function which aggregates everything and returns a consistent output.

Jeff Kirsher says:
====================
40GbE Intel Wired LAN Driver Updates 2017-03-20
This series contains updates to i40e and i40evf only.
Philippe Reynes updates i40e and i40evf to use the new ethtool API for
{get|set}_link_ksettings.
Jake provides the remaining patches in the series, starting with a fix
for i40e where the firmware expected the port numbers for the offloaded
UDP tunnels in Little Endian format and we were sending them in Big Endian
format which put the wrong port number to be put in the UDP tunnel list.
Changed the driver to use __be32 values instead of arrays for
(src|dst)_ip. Refactored the exit flow of i40e_add_fdir_ethtool() which
removes the dependency on having a non-zero return value. Fixed a memory
leak by running kfree() and returning immediately when we fail to add
flow director filter. Fixed a potential issue where could update the
filter count without actually succeeding in adding a filter, by moving
the ATR exit check to after we have sent the TCP/IPv4 filter to the ring
successfully. Ensures that the fd_tcp_rule count is reset to 0, before
we reprogram the filters so that we do not end up with a stale count
which does not correctly reflect the number of programmed filters. Added
a check whether we have TCP/IPv4 filters before re-enabling ATR after
flushing and replaying FDIR filters. Added counters for each filter
type in preparation for adding code to properly check the mask value.
Fixed potential issues by explicitly checking the flow type at the
start of i40e_add_fdir_ethtool(). To avoid possible memory leaks,
we now unconditionally delete the old filter, even if it is identical to
the new filter and ensures will always update the filters as expected.

The previous code relied on i40e_match_fdir_input_set to determine when
determining whether to free the old filter. Change this code so that we
simply unconditionally delete the old filter, even if it's identical to
the new filter. This ensures that we don't leak any memory, and that we
always update the filters as expected.

Although we will fail the filter later due to checking flow_type which
will have a bogus invalid type, it is possible future refactoring will
remove this hidden failure case. Avoid a possible issue in the future by
explicitly checking the flow type at the start.

In preparation for adding code to properly check the mask values, we
will need to know the number of active filters for each type. Add
counters for each filter type. Rename the already existing fd_tcp_rule
to fd_tcp4_filter_cnt to match the style of other names. To avoid style
warnings, avoid assigning multiple parameters at once, and fix up one
other case where we did so previously.

When flushing and replaying FDIR filters, it is possible we would
disable ATR, and then re-enable it even though we should have kept
it disabled due to existing TCP/IPv4 filters. Fix this by checking
whether we have TCP4/IPv4 filters before re-enabling.
Alternatively, we could instead restore ATR and then replay filters,
however, this would cause us to rapidly enable and then disable ATR in
some cases.

Instead of setting err=true and checking this to determine when to free
the raw_packet near the end of the function, simply kfree and return
immediately. The resulting code is a bit cleaner and has one less
variable. This also resolves a subtle bug in the ipv4 case which could
fail to add the first filter and then never free the memory, resulting
in a small memory leak.

The code originally included src_ip and dst_ip with enough space to
support ipv6 filters. However, no actual support for ipv6 filters has
been implemented. Thus, remove the arrays and just use __be32 values.
Should ipv6 support be added in the future, we can replace these with
a union that has sizes for both values.

The firmware expects the port numbers for offloaded UDP tunnels in
Little Endian format. We accidentally sent the value in Big Endian
format which obviously will cause the wrong port number to be put into
the UDP tunnels list. This results in VxLAN and Geneve tunnel Rx
offloads being essentially disabled, unless the port number happens to
be identical after byte swapping. Note that i40e_aq_add_udp_tunnel()
will byteswap the parameter from host order into Little Endian so we
don't need worry about passing strictly a __le16 value to the command.
This patch essentially reverts b3f5c7bc88ba ("i40e: Fix for extra byte
swap in tunnel setup", 2016-08-24), but in a way that makes the result
much more clear to the reader.
