setup_wait() and tc_offload_check() both assume that all NUM_NETIFS
interfaces are relevant for a given test. However, the scale test script
acts as an umbrella for a number of sub-tests, some of which may not
require all the interfaces.
Thus it's suboptimal for tc_offload_check() to query all the interfaces.
In case of setup_wait() it's incorrect, because the sub-test in question
of course doesn't configure any interfaces beyond what it needs, and
setup_wait() then ends up waiting indefinitely for the extraneous
interfaces to come up.
For that reason, give setup_wait() and tc_offload_check() an optional
parameter with a number of interfaces to probe. Fall back to global
NUM_NETIFS if the parameter is not given.

nfp: flower updates and netconsole
This set contains assorted updates to driver base and flower.
First patch is a follow up to a fix to calculating counters which
went into net. For ethtool counters we should also make sure
they are visible even after ring reconfiguration. Next patch
is a safety measure in case we are running on a machine with a
broken BIOS we should fail the probe when risk of incorrect
operation is too high. The next two patches add netpoll support
and make use of napi_consume_skb(). Last we populate bus info
on all representors.
Pieter adds support for offload of the checksum action in flower.
John follows up to another fix he's done in net, we set TTL
values on tunnels to stack's default, now Johns does a full
route lookup to get a more precise information, he populates
ToS field as well. Last but not least he follows up on Jiri's

Currently the NFP fw only supports L3/L4 hashing so rejects the offload of
filters that output to LAG ports implementing other hash algorithms. Team,
however, uses a BPF function for the hash that is not defined. To support
Team offload, accept hashes that are defined as 'unknown' (only Team
defines such hash types). In this case, use the NFP default of L3/L4
hashing for egress port selection.

It seems these attempts are futile, we need to link the

A peer node is considered down if there are no
active links (or) lost contact to the node. In current implementation,
a peer node instance is deleted either if
a) TIPC module is removed (or)
b) Application can use a netlink/iproute2 interface to delete a
specific down node.
Thus, a down node instance lives in the system forever, unless the
application explicitly removes it.
We fix this by deleting the nodes which are down for
a specified amount of time (5 minutes).

The very first version of RTL8169 from 2002 (and only this one) has
support for a TBI 1000BaseX fiber interface. The TBI support in the
driver makes switching to phylib tricky, so best would be to get
rid of it. I found no report from anybody using a device with RTL8169
and fiber interface, also the vendor driver doesn't support this mode
(any longer).
So remove TBI support and bail out with a message if a card with

out there, we could add a stripped-down version of the driver
supporting chip version 01 and TBI only (and maybe move it to

The function tipc_msg_extract() is using skb_clone() to clone inner
messages from a message bundle buffer. Although this method is safe,
it has an undesired effect that each buffer clone inherits the
true-size of the bundling buffer. As a result, the buffer clone
almost always ends up with being copied anyway by the message
validation function. This makes the cloning into a sub-optimization.
In this commit we take the consequence of this realization, and copy
each inner message to a separately allocated buffer up front in the
extraction function.
As a bonus we can now eliminate the two cases where we had to copy
re-routed packets that may potentially go out on the wire again.

SMC supports two variants: SMC-R and SMC-D. For data transport, SMC-R
uses RDMA devices, SMC-D uses so-called Internal Shared Memory (ISM)
devices. An ISM device only allows shared memory communication between
SMC instances on the same machine. For example, this allows virtual
machines on the same host to communicate via SMC without RDMA devices.
This patch adds the base infrastructure for SMC-D and ISM devices to
the existing SMC code. It contains the following:
* ISM driver interface:
This interface allows an ISM driver to register ISM devices in SMC. In
the process, the driver provides a set of device ops for each device.
SMC uses these ops to execute SMC specific operations on or transfer
data over the device.
* Core SMC-D link group, connection, and buffer support:
Link groups, SMC connections and SMC buffers (in smc_core) are
extended to support SMC-D.
* SMC type checks:
Some type checks are added to prevent using SMC-R specific code for
SMC-D and vice versa.
To actually use SMC-D, additional changes to pnetid, CLC, CDC, etc. are
required. These are added in follow-up patches.

The SMC protocol requires to send a separate consumer cursor update,
if it cannot be piggybacked to updates of the producer cursor.
Currently the decision to send a separate consumer cursor update
just considers the amount of data already received by the socket
program. It does not consider the amount of data already arrived, but
not yet consumed by the receiver. Basing the decision on the
difference between already confirmed and already arrived data
(instead of difference between already confirmed and already consumed
data), may lead to a somewhat earlier consumer cursor update send in

For SMC it is important to know the current port state of RoCE devices.
Monitoring port states has been triggered, when a RoCE device was added
to the pnet table. To support future alternatives to the pnet table the
monitoring of ports is made independent of the existence of a pnet table.
It starts once the smc_ib_device is established.
Due to this change smc_ib_remember_port_attr() is now a local function
and shuffling its location and the location of its used functions
makes any forward references obsolete.
