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.

The compiler warned on an oddly indented bit of code, and when

a call to AQ, but then the aq_ret would be checked unconditionally

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
interrupts handlers and instead directly invoking the main crq interrupt
handler. This will ensure that we see the transport event necessary to
properly resume the driver.

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.

This patch is a part of a patch-set that introduces support for
VF-reps in the bnxt_en driver. The driver registers eswitch mode
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.
The next patch in the series, adds the RX/TX routines and a slim
netdev implementation for the VF-reps.

This patch adds changelink rtnl operation support for geneve devices
and the code changes involve:
- added geneve_quiesce() which quiesces the geneve device data path
for both TX and RX. This lets us perform the changelink operation
atomically w.r.t data path. Also added geneve_unquiesce() to
reverse the operation of geneve_quiesce().
- refactor geneve_newlink into geneve_nl2info to be used by both
geneve_newlink and geneve_changelink
- geneve_nl2info takes a changelink boolean argument to isolate
changelink checks.
- Allow changing only a few attributes (ttl, tos, and remote tunnel
endpoint IP address (within the same address family)):
- return -EOPNOTSUPP for attributes that cannot be changed for
now. Incremental patches can make the non-supported one
available in the future if needed.

We currently reset the device during XDP set, the main reason is
that we allocate more headroom with XDP (for header adjustment).
This works but causes network downtime for users.
Previous patches encoded the headroom in the buffer context,
this makes it possible to detect the case where a buffer
with headroom insufficient for XDP is added to the queue and
XDP is enabled afterwards.
Upon detection, we handle this case by copying the packet
