cls_bpf now guarantees that only device-bound programs are
allowed with skip_sw. The drivers no longer pay attention to
flags on filter load, therefore the bpf_offload member can be
removed. If flags are needed again they should probably be
added to struct tc_cls_common_offload instead.

Rename the tc_cls_common_offload_init() helper function to
tc_cls_common_offload_init_deprecated() and add a new implementation
which also takes flags argument. We will only set extack if flags
indicate that offload is forced (skip_sw) otherwise driver errors
should be ignored, as they don't influence the overall filter
installation.
Note that we need the tc_skip_hw() helper for new version, therefore
it is added later in the file.

Work requests are needed for every ib_post_send(), among them the
ib_post_send() to signal closing. If an smc socket program is cancelled,
the smc connections should be cleaned up, and require sending of closing
signals to the peer. This may fail, if a wait for
a free work request is needed, but is cancelled immediately due to the
cancel interrupt. To guarantee notification of the peer, the wait for
a work request is changed to uninterruptible.
And the area to receive work request completion info with
ib_poll_cq() is cleared first.

Make netdevsim print a message to the BPF verifier log buffer when a
program is offloaded.
Then use this message in hardware offload selftests to make sure that
using this buffer actually prints the message to the console for
eBPF hardware offload.
The message is appended after the last instruction is processed with the
verifying function from netdevsim. Output looks like the following:
$ tc filter add dev foo ingress bpf obj sample_ret0.o \
sec .text verbose skip_sw
Prog section '.text' loaded (5)!
- Type: 3

"verbose" flag is required to see it in the console since netdevsim does
not throw an error after printing the message.

40GbE Intel Wired LAN Driver Updates 2018-01-23
This series contains updates to i40e and i40evf only.
Pawel enables FlatNVM support on x722 devices by allowing nvmupdate tool
to configure the preservation flags in the AdminQ command.
Mitch fixes a potential divide by zero error when DCB is enabled and
the firmware fails to configure the VSI, so check for this state.
Fixed a bug where the driver could fail to adhere to ETS bandwidth
allocations if 8 traffic classes were configured on the switch.
Sudheer fixes a potential deadlock by avoiding to call
flush_schedule_work() in i40evf_remove(), since cancel_work_sync()
and cancel_delayed_work_sync() already cleans up necessary work items.
Fixed an issue with the problematic detection and recovery from
hung queues in the PF which was causing lost interrupts. This is done
by triggering a software interrupt so that interrupts are forced on
and if we are already in napi_poll and an interrupt fires, napi_poll
will not be rescheduled and the interrupt is lost.
Avinash fixes an issue in the VF where is was possible to issue a
reset_task while the device is currently being removed.
Michal fixes an issue occurring while calling i40e_led_set() with
the blink parameter set to true, which was causing the activity LED
instead of the link LED to blink for port identification.
Shiraz changes the client interface to not call client close/open on
netdev down/up events, since this causes a lot of thrash that is
not needed. Instead, disable the PE TCP-ENA flag during a netdev
down event and re-enable on a netdev up event, since this blocks all
TCP traffic to the RDMA protocol engine.
Alan fixes an issue which was causing a potential transmit hang by
ignoring the PF link up message if the VF state is not yet in the
RUNNING state.
Amritha fixes the channel VSI recreation during the reset flow to
reconfigure the transmit rings and the queue context associated with
the channel VSI.

# ip link add name eth1 type dummy
# ip link set dev eth1 up
# tc qdisc add dev eth1 root handle 1: prio

It takes 1sec for bond link down notification to hit user-space
when all slaves of the bond go down. 1sec is too long for
protocol daemons in user-space relying on bond notification
to recover (eg: multichassis lag implementations in user-space).
Since the link event code already marks team device port link events
as urgent, this patch moves the code to cover all lag ports and master.

10GbE Intel Wired LAN Driver Updates 2018-01-23
This series contains updates to ixgbe only.
Shannon Nelson provides an implementation of the ipsec hardware offload
feature for the ixgbe driver for these devices: x540, x550, 82599.
The ixgbe NICs support ipsec offload for 1024 Rx and 1024 Tx Security
Associations (SAs), using up to 128 inbound IP addresses, and using the
rfc4106(gcm(aes)) encryption. This code does not yet support checksum
offload, or TSO in conjunction with the ipsec offload - those will be
added in the future.
This code shows improvements in both packet throughput and CPU utilization.
For example, here are some quicky numbers that show the magnitude of the
performance gain on a single run of "iperf -c <dest>" with the ipsec
offload on both ends of a point-to-point connection:
9.4 Gbps - normal case
7.6 Gbps - ipsec with offload
343 Mbps - ipsec no offload

* Introduce dsa_port_link_(un)register_of and mark the fixed
variant static.
* Update patch description to describe the phy<->phy connection
from i210 to the Marvell switch
Changes since PATCHv3:
* Enable the phy in dsa_port_setup() instead of abusing the
fixed link setup function
Changes since PATCHv2:
* Add phy nodes to switch in bx50.dtsi and reference them
from switch ports
* Enable cpu-port's phy based on 'phy-handle' instead of 'phy-mode'
Changes since PATCHv1:
* Use 'marvell,mv88e6085' instead of introducing compatible
string for mv88e6240.
* Fix indention of DT nodes
* Only enable 'cpu' phy, if explicitly set to "internal".

This adds support for enabling the internal PHY for a 'cpu' port.
It has been tested on GE B850v3, B650v3 and B450v3, which have a
built-in MV88E6240 switch hardwired to a PCIe based network card.
On these machines the internal PHY of the i210 network card and
the Marvell switch are connected to each other and must be enabled
for properly using the switch. While the i210 PHY will be enabled
when the network interface is enabled, the switch's port is not
exposed as network interface. Additionally the mv88e6xxx driver
resets the chip during probe, so the PHY is disabled without this
patch.

Fix recreating the channel VSIs during the reset flow to reconfigure
the Tx rings and the queue context associated with the channel VSI.
Also update the next_base_queue for the VSI while rebuilding the
channel VSIs after a reset.

If we receive the link status message from PF with link up before queues
are actually enabled, it will trigger a TX hang. This fixes the issue
by ignoring a link up message if the VF state is not yet in RUNNING
state.

Client close is overloaded to handle both un-registration and
netdev down event. On netdev down, i40iw client close is called
which unregisters the RDMA dev and this is too destructive
since the netdev is still registered.
Do not call client close/open on netdev down/up events. Instead
disable the PE TCP_ENA flag during a netdev down event. This
blocks all TCP traffic to the RDMA Protocol Engine. On netdev up,
re-enable the flag.

Now that i40e_vsi_config_tc() has the pf and hw variable defined, use
them, instead of dereferencing vsi->back. Much easier to read.

The driver (and the entire netdev layer for that matter) assumes
that TC0 will always be present in our DCB configuration.
Unfortunately, this isn't always the case. Rather than fail to
configure the VSI, let's go ahead and try to make it work, even
though DCB will end up being disabled by the kernel.
If the driver fails to configure DCB, the driver queries what's
valid, then writes that back to the hardware, always forcing TC0.
This fixes a bug where the driver could fail to adhere to ETS BW
allocations if 8 TCs were configured on the switch.
