40GbE Intel Wired LAN Driver Updates 2017-07-25
This series contains updates to i40e and i40evf only.
Gustavo Silva fixes a variable assignment, where the incorrect variable
was being used to store the error parameter.
Carolyn provides a fix for a problem found in systems when entering S4
state, by ensuring that the misc vector's IRQ is disabled as well.
Jake removes the single-threaded restriction on the module workqueue,
which was causing issues with events such as CORER. Does some future
proofing, by changing how the driver displays the UDP tunnel type.
Paul adds a retry in releasing resources if the admin queue times out
during the first attempt to release the resources.
Jesse fixes up references to 32bit timspec, since there are a small set
of errors on 32 bit, so we need to be using the right calls for dealing
with timespec64 variables. Cleaned up code indentation and corrected
an "if" conditional check, as well as making the code flow more clear.
Cast or changed the types to remove warnings for comparing signed and
unsigned types. Adds missing includes in i40evf, which were being used
but were not being directly included.
Daniel Borkmann fixes i40e to fill the XDP prog_id with the id just like
other XDP enabled drivers, so that on dump we can retrieve the attached
program based on the id and dump BPF insns, opcodes, etc back to user
space.
Tushar Dave adds le32_to_cpu while evaluating the hardware descriptor
fields, since they are in little-endian format. Also removed
unnecessary "__packed" to a couple of i40evf structures.
Stefan Assmann fixes an issue when an administratively set MAC was set
and should now be switched back to 00:00:00:00:00:00, the pf_set_mac
flag is not being toggled back to false.

The i40e driver attempts to display the UDP tunnel name by doing a check
against the type, where for non-zero types we use "vxlan" and for zero
type we use "geneve". This is not future proof, because if new tunnel
types get added, we'll incorrectly label them. It also depends on the
value of UDP_TUNNEL_TYPE_GENEVE == 0, which is brittle.
Instead, replace this with a function that can return a constant string
depending on the type. For now we'll use "unknown" for types we don't
know about, and we can expand this in the future if new types get added.

During certain events such as a CORER, multiple devices will run a work
task to handle some cleanup. This can cause issues due to
a single-threaded workqueue which can mean that a device doesn't cleanup
in time. Prevent this by removing the single-threaded restriction on the
module workqueue. This avoids the need to add more complex yielding
logic in our service task routine. This is also similar to what other
drivers such as fm10k do.

When a netdev (PF netdev or representor) is opened or closed, set the
physical port config bit appropriately - which powers UP/DOWN the PHY
module for the physical interface.
The PHY is powered first in the HW/FW configuration step when opening
the netdev and again last in the HW/FW configuration step when closing
the netdev.
This is only applicable when there is a physical port associated with
the netdev and if the NSP support this. Otherwise we silently ignore
this step.
The 'nfp_eth_set_configured' can actually return positive values -
updated the function documentation appropriately.

On resume, the ibmvnic driver will fail to resume normal operation.
The main crq gets closed on suspend by the vnic server and doesn't get
reopened again as the interrupt for the transport event that would reset
the main crq comes in after the driver has been suspended.
This patch resolves the issue by removing the calls to kick the receive

handler. This will ensure that we see the transport event necessary to

This patch introduces the RX/TX and a simple netdev implementation
for VF-reps. The VF-reps use the RX/TX rings of the PF. For each VF-rep
the PF driver issues a VFR_ALLOC FW cmd that returns "cfa_code"
and "cfa_action" values. The FW sets up the filter tables in such
a way that VF traffic by default (in absence of other rules)
gets punted to the parent PF. The cfa_code value in the RX-compl
informs the driver of the source VF. For traffic being transmitted
from the VF-rep, the TX BD is tagged with a cfa_action value that
informs the HW to punt it to the corresponding VF.

get/set methods with the devlink interface that allow a user to
enable SRIOV switchdev mode. When enabled, the driver registers
a VF-rep netdev object for each VF with the stack. This can
essentially bring the VFs unders the management perview of the
hypervisor and applications such as OVS.
