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.

A null check is needed after all. netlink skbs can have skb->head be
backed by vmalloc. The netlink destructor vfree()s head, then sets it to
NULL. We then panic in skb_release_data with a NULL dereference.
Re-add such a test.
Alternative would be to switch to kvfree to free skb->head memory
and remove the special handling in netlink destructor.

====================
rxrpc: Rearrange headers
Here's a pair of patches that rearrange some of the AF_RXRPC header files
that are outside of the net/rxrpc/ directory:
(1) The bits userspace need are moved to uapi/linux/rxrpc.h. [Should this
be af_rxrpc.h instead, I wonder - but there doesn't seem to be
precedent for that in the other net UAPI headers.]
(2) For the most part, the contents of rxrpc/packet.h are no longer used
outside of the AF_RXRPC module, so move them to net/rxrpc/protocol.h
with the exception of the standard abort codes which are exposed to
userspace when an abort occurs and the security index values which are
needed when constructing keys.

All this kind of typedef's using should be removed. This patchset is the
