Add the definitions related to creation/deletion of a modify header
context and the modify header steering action which are used for HW
packet header modify (re-write) as part of steering. Add as well the
modify header id into two intermediate structs and set it to the FTE.
Note that as the push/pop vlan steering actions are emulated by the
ewitch management code, we're not breaking any compatibility while
changing their values to make room for the modify header action which
is not emulated and whose value is part of the FW API. The new bit
values for the emulated actions are at the end of the possible range.

The code for adding tc fdb flows leaves things half set when it fails
in the middle. Currently we are not leaking things (e.g eswitch
vlan reference, encap reference and HW resources) since the main
code to add flower rules does a cleanup by calling mlx5e_tc_del_flow().
This cleanup further works just b/c we're checking there if the HW rule
for the flow we are attempting to delete is valid before touching it, and
since under the current possible combinations of supported actions it's okay
to go and blidnly deref or delete all the action related resources (encap, vlan).
Instead, do things properly, namely make sure that if add flow fails we
clean all what was allocated or referenced. Now, the flow delete code can
blindly deref/deallocate both the rule and the actions related resources and
when more action combinations are introduced (such as the upcoming header
re-write) we are fine with clear and robust code.
While here, align all of nic/fdb parse actions/add flow functions to get
mlx5e_tc_flow struct param and pick the attributes or whatever else needed
from there.

This series provides a fail-safe mechanism to allow safely re-configuring
mlx5e netdevice and provides a resiliency against sporadic
configuration failures.
To enable this we do some refactoring and code reorganizing to allow
breaking the drivers open/close flows to stages:
open -> activate -> deactivate -> close.
In addition we need to allow creating fresh HW ring resources
(mlx5e_channels) with their own "new" set of parameters, while keeping
the current ones running and active until the new channels are
successfully created with the new configuration, and only then we can
safly replace (switch) old channels with new ones.
For that we introduce mlx5e_channels object and an API to manage it:
- channels = open_channels(new_params):
open fresh TX/RX channels
- activate_channels(channels):
redirect traffic to them and attach them to the netdev
- deactivate_channes(channels)
stop traffic and detach from netdev
- close(channels)
Free the TX/RX HW resources of those channels
With the above strategy it is straightforward to achieve the desired
behavior of fail-safe configuration. In pseudo code:
make_new_config(new_params)
{
old_channels = current_active_channels;
new_channels = create_channels(new_params);
if (!new_channels)
return "Failed, but current channels are still active :)"

is a possibility of failure in retrieving these values but caller has
to assume it's always successful. This leads to having inconsistent
slave link settings. If these (speed, duplex) values cannot be
retrieved, then keeping the link UP causes problems.
The updated bond_update_speed_duplex() returns 0 on success if it
retrieves sane values for speed and duplex. On failure it returns 1

The primary issue is that mii-inspect phase updates link-state and
expects changes to be committed during the mii-commit phase. After
the inspect phase if it fails to acquire rtnl-mutex, the commit
phase (bond_mii_commit) doesn't get to run. This partially updated
state stays and makes the internal-state inconsistent.
e.g. setup bond0 => slaves: eth1, eth2
eth1 goes DOWN -> UP
mii_monitor()
mii-inspect()
bond_set_slave_link_state(eth1, UP, DontNotify)
rtnl_trylock() <- fails!
Next mii-monitor round
eth1: No change
mii_monitor()
mii-inspect()
eth1->link == current-status (ethtool_ops->get_link)
no-change-detected
End result:
eth1:
Link = BOND_LINK_UP
Speed = 0xfffff [SpeedUnknown]
Duplex = 0xff [DuplexUnknown]
This doesn't always happen but for some unlucky machines in a large set
of machines it creates problems.
The fix for this is to avoid making changes during inspect phase and
postpone them until acquiring the rtnl-mutex / invoking commit phase.

Probably due to some mis-merging fix a bug associated with commits
d7ce6422d6 ("i40e: don't check params until after checking for client
instance", 2017-02-09) and 3140aa9a78c9 ("i40e: KISS the client
interface", 2017-03-14)
The first commit tried to move the initialization of the params
structure so that we didn't bother doing this if we didn't have a client
interface. You can already see that it looks fishy because of the
indentation. The second commit refactors a bunch of the interface, and
incorrectly drops the params initialization.
I believe what occurred is that internally the two patches were
re-ordered, and the merge conflicts as a result were performed
incorrectly.
Fix the use of an uninitialized variable by correctly initializing the
params variable via i40e_client_get_params().

First, this patch eliminates IOMMU DMAR Faults caused by VF hardware.
This is done by enabling VF hardware only after VSI resources are
freed. Otherwise, hardware could DMA into memory that is (or just has
been) being freed.
Then, the VF driver is activated only after VSI resources have been
reallocated. That's because the VF driver can request resources
immediately after it's activated. So they need to be ready at that
point.
The second race condition happens when the OS initiates a VF reset,
and then before it's finished modifies VF's settings by changing its
MAC, VLAN ID, bandwidth allocation, anti-spoof checking, etc. These
functions needed to be blocked while VF is undergoing reset. Otherwise,
they could operate on data structures that had just been freed or not
yet fully initialized.

Update the driver code so that we do bulk updates of the page reference
count instead of just incrementing it by one reference at a time. The
advantage to doing this is that we cut down on atomic operations and
this in turn should give us a slight improvement in cycles per packet.
In addition if we eventually move this over to using build_skb the gains
will be more noticeable.
I also found and fixed a store forwarding stall from where we were
assigning "*new_buff = *old_buff". By breaking it up into individual
copies we can avoid this and as a result the performance is slightly
improved.

The GTP-tunnel driver is explicitly GGSN-side as it searches for PDP
contexts based on the incoming packets _destination_ address. If we
want to place ourselves on the SGSN side of the tunnel, then we want
to be identifying PDP contexts based on _source_ address.
Let it be noted that in a "real" configuration this module would never
be used: the SGSN normally does not see IP packets as input. The
justification for this functionality is for PGW load-testing applications
where the input to the SGSN is locally generally IP traffic.
This patch adds a "role" argument at GTP-link creation time to specify
whether we are on the GGSN or SGSN side of the tunnel; this flag is then
used to determine which part of the IP packet to use in determining
the PDP context.

40GbE Intel Wired LAN Driver Updates 2017-03-23
This series contains updates to i40e and i40e.txt documentation.
Jake provides all the changes in the series which are centered around
ntuple filter fixes and additional support. Fixed the current
implementation of .set_rxnfc, where we were not reading the mask field
for filter entries which was resulting in filters not behaving as
expected and not working correctly. When cleaning up after disabling
flow director support, ensure that the default input set is correctly
reprogrammed. Since the hardware only supports a single input set for
all flows of that type, the driver shall only allow the input set to
change if there are no other configured filters for that flow type, so
add support to detect when we can update the input set for each flow
type. Align the driver to other drivers to partition the ring_cookie
value into 8bits of VF index, along with 32bits of queue number instead
of using the user-def field. Added support to parse the user-def field
into a data structure format to allow future extensions of the user-def
filed by keeping all the code that read/writes the field into a single
location. Added support for flexible payloads passed via ethtool
user-def field. We support a single flexible word (2byte) value per
protocol type, and we handle the FLX_PIT register using a list of
flexible entries so that each flow type may be configured separately.
Enabled flow director filters for SCTPv4 packets using the ethtool
ntuple interface to enable filters. Updated the documentation on the
i40e driver to include the newly added support to ntuple filters.
Reduced complexity of a if-continue-else-break section of code by
taking advantage of using hlist_for_each_entry_continue() instead.

The PF driver is incorrectly resetting Octeon when the module parameter
"fw_type=none" is there. "fw_type=none" means the PF should not load any
firmware to the NIC because Octeon is already running preloaded firmware.
Fix it by putting an if (fw_type != none) around the reset code.
Because the Octeon reset is now conditionally gone, when unloading the
driver, conditionally send the RESET_PF command to the firmware who will
then free up PF-related data structures.

Replace a complex if->continue->else->break construction in
i40e_next_filter. We can simply use hlist_for_each_entry_continue
instead. This drops a lot of confusing code. The resulting code is much
easier to understand the intention, and follows the more normal pattern
for using hlist loops. We could have also used a break with a "return
next" at the end of the function, instead of return NULL, but the
current implementation is explicitly clear that when you reach the end
of the loop you get a NULL value. The alternative construction is less
clear since the reader would have to know that next is NULL at the end
of the loop.

Add support for flexible payloads passed via ethtool user-def field.
This support is somewhat limited due to hardware design. The input set
can only be programmed once per filter type, and the flexible offset is
part of this filter input set. This means that the user cannot program
both a regular and a flexible filter at the same time for a given flow
type. Additionally, the user may not program two flexible filters of the
same flow type with different offsets, although they are allowed to
configure different values at that offset location.
We support a single flexible word (2byte) value per protocol type, and
we handle the FLX_PIT register using a list of flexible entries so that
each flow type may be configured separately.
Due to hardware implementation, the flexible data is offset from the
start of the packet payload, and thus may not be in part of the header
data. For this reason, the offset provided by the user defined data is
interpreted as a byte offset from the start of the matching payload.
Previous implementations have tried to represent the offset as from the
start of the frame, but this is not feasible because header sizes may
change due to options.

Add code to parse the user-def field into a data structure format. This
code is intended to allow future extensions of the user-def field by
keeping all code that actually reads and writes the field into a single
location. This ensures that we do not litter the driver with references
to the user-def field and minimizes the amount of bitwise operations we
need to do on the data.
Add code which parses the lower 32bits into a flexible word and its
offset. This will be used in a future patch to enable flexible filters
which can match on some arbitrary data in the packet payload. For now,
we just return -EOPNOTSUPP when this is used.
Add code to fill in the user-def field when reporting the filter back,
even though we don't actually implement any user-def fields yet.
Additionally, ensure that we mask the extended FLOW_EXT bit from the
flow_type now that we will be accepting filters which have the FLOW_EXT
bit set (and thus make use of the user-def field).

Add support to detect when we can update the input set for each flow
type.
Because the hardware only supports a single input set for all flows of
that matching type, the driver shall only allow the input set to change
if there are no other configured filters for that flow type.
Thus, the first filter added for each flow type is allowed to change the
input set, and all future filters must match the same input set. Display
a diagnostic message whenever the filter input set changes, and
a warning whenever a filter cannot be accepted because it does not match
the configured input set.

Ensure that the default input set is correctly reprogrammed when
cleaning up after disabling flow director support. This ensures that the
programmed value will be in a clean state.
Although we do not yet have support for SCTPv4 filters, a future patch
will add support for this protocol, so we will correctly restore the
SCTPv4 input set here as well. Note that strictly speaking the default
hardware value for SCTP includes matching the verification tag. However,
the ethtool API does not have support for specifying this value, so
there is no reason to keep the verification field enabled.
This patch is the next step on the way to enabling partial tuple filters
which will be implemented in a following patch.

Do not assume that hardware has been programmed with the default mask,
but instead read the input set registers to determine what is currently
programmed. This ensures that all programmed filters match exactly how
the hardware will interpret them, avoiding confusion regarding filter
behavior.
This sets the initial ground-work for allowing custom input sets where
some fields are disabled. A future patch will fully implement this
feature.
Instead of using bitwise negation, we'll just explicitly check for the
correct value. The use of htonl and htons are used to silence sparse
warnings. The compiler should be able to handle the constant value and
avoid actually performing a byteswap.

The current implementation of .set_rxnfc does not properly read the mask
field for filter entries. This results in incorrect driver behavior, as
we do not reject filters which have masks set to ignore some fields. The
current implementation simply assumes that every part of the tuple or
"input set" is specified. This results in filters not behaving as
expected, and not working correctly.
As a first step in supporting some partial filters, add code which
checks the mask fields and rejects any filters which do not have an
acceptable mask. For now, we just assume that all fields must be set.
This will get the driver one step towards allowing some partial filters.
At a minimum, the ethtool commands which previously installed filters
that would not function will now return a non-zero exit code indicating
failure instead.
We should now be meeting the minimum requirements of the .set_rxnfc API,
by ensuring that all filters we program have a valid mask value for each
field.
Finally, add code to report the mask correctly so that the ethtool
command properly reports the mask to the user.
Note that the typecast to (__be16) when checking source and destination
port masks is required because the ~ bitwise negation operator does not
correctly handle variables other than integer size.

in case caller accidentally passes a smaller member instead of union].
Change implementation so that caller could pass a pointer to any

Interaction of driver -> management firmware is based
on a one-pending mailbox [per interface], and various
mailbox commands need to be synchronized.
Current scheme is messy, and there's a difficulty extending
it as it deals differently with various commands as well as
making assumption on the required behavior for load/unload
requests.
Drop the current scheme into a completion-list-based approach;
Each flow would try sending the command when possible,
allowing one flow to complete another flow's completion and
relieve the mailbox before sending its own command.

Access to hardware resources is arbitrated using locks residing
in device memory. Currently nfpcore only respects the mutexes
when it comes to inter-host locking, but if we try to acquire
the same lock again, on one host - it will simply return success
because owner of the lock is already set to that host.
This makes the locks useless for arbitration within one host
and unfair because whichever host grabbed the lock will have
a chance to reacquire it without others getting a shot.

Commit 6ac3ce8295 ("net: bcmgenet: Remove excessive PHY reset")
removed the bcmgenet_mii_reset() function from bcmgenet_power_up() and
bcmgenet_internal_phy_setup() functions. In so doing it broke the reset
of the internal PHY devices used by the GENETv1-GENETv3 which required
this reset before the UniMAC was enabled. It also broke the internal
GPHY devices used by the GENETv4 because the config_init that installed
the AFE workaround was no longer occurring after the reset of the GPHY
performed by bcmgenet_phy_power_set() in bcmgenet_internal_phy_setup().
In addition the code in bcmgenet_internal_phy_setup() related to the
"enable APD" comment goes with the bcmgenet_mii_reset() so it should
have also been removed.
Commit bd4060a610 ("net: bcmgenet: Power on integrated GPHY in
bcmgenet_power_up()") moved the bcmgenet_phy_power_set() call to the
bcmgenet_power_up() function, but failed to remove it from the
bcmgenet_internal_phy_setup() function. Had it done so, the
bcmgenet_internal_phy_setup() function would have been empty and could
have been removed at that time.
Commit 5dbebbb44a ("net: bcmgenet: Software reset EPHY after power on")
was submitted to correct the functional problems introduced by
commit 6ac3ce8295 ("net: bcmgenet: Remove excessive PHY reset"). It
was included in v4.4 and made available on 4.3-stable. Unfortunately,
it didn't fully revert the commit because this bcmgenet_mii_reset()
doesn't apply the soft reset to the internal GPHY used by GENETv4 like
the previous one did. This prevents the restoration of the AFE work-
arounds for internal GPHY devices after the bcmgenet_phy_power_set() in
bcmgenet_internal_phy_setup().
This commit takes the alternate approach of removing the unnecessary
bcmgenet_internal_phy_setup() function which shouldn't have been in v4.3
so that when bcmgenet_mii_reset() was restored it should have only gone
into bcmgenet_power_up(). This will avoid the problems while also
removing the redundancy (and hopefully some of the confusion).

The VF reps are effectively related to the same mlx5 PCI device as the

FW erred on multiple vxlan dst port deletes when the port was deleted

We fix that by keeping the registration to be carried out only by the

up a port there and realize if they are ok to offload that.
