This series contains updates to ice driver only.

Akeem enables MAC anti-spoofing by default when a new VSI is being
created.  Fixes an issue when reclaiming VF resources back to the pool
after reset, by freeing VF resources separately using the first VF
vector index to traverse the list, instead of starting at the last
assigned vectors list.  Added support for VF & PF promiscuous mode in
the ice driver.  Fixed the PF driver from letting the VF know it is "not
trusted" when it attempts to add more than its permitted additional MAC
addresses.  Altered how the driver gets the VF VSIs instances, instead
of using the mailbox messages to retrieve VSIs, get it directly via the
VF object in the PF data structure.

Bruce fixes return values to resolve static analysis warnings.  Made
whitespace changes to increase readability and reduce code wrapping.

Anirudh cleans up code by removing a function prototype that was never
implemented and removed an unused field in the ice_sched_vsi_info
structure.

Kiran fixes a potential divide by zero issue by adding a check.

Victor cleans up the transmit scheduler by adjusting the stack variable
usage and added/modified debug prints to make them more useful.

Yashaswini updates the driver in VEB mode to ensure that the LAN_EN bit
is set if all the right conditions are met.

Christopher ensures the loopback enable bit is not set for prune switch
rules, since all transmit traffic would be looped back to the internal
switch and dropped.

The following are changes since commit 3b0f31f2b8c9fb348e4530b88f6b64f9621f83d6:
  genetlink: make policy common to family

From: Akeem G Abodunrin <akeem.g.abodunrin@intel.com>

This patch fixes issue reclaiming VF resources back to the pool after
reset - Since we only allocate HW vector for all VFs and track together
with resources allocation for PF with ice_search_res, we need to free VFs
resources separately, using first VF vector index to traverse the list.
Otherwise tracker starts from the last assigned vectors list and causes
maximum supported number of HW vectors, 1024 to be exhausted, depending on
the number of VFs enabled, which causes a lot of unwanted issues, and
failed to reassign vectors for VFs.

When VF requested for queues changes, we need to update LAN Tx queue with
correct number of VF queue pairs and re-allocate VF resources based on
this new requested number of queues, which is constraint within maximum
queue supported per VF.

Static analysis flagged a potential divide by zero error because
vsi->num_rxq can become zero in certain condition and it is used as
divisor.

Put the return type on a separate line for function prototypes and
signatures that would exceed the 80-character limit if both were on
the same line.

This patch does some clean up in the Tx scheduler code:

1. Adjust the stack variable usage
2. Modify the debug prints to display the FW error
3. Add additional debug prints while adding/removing VSIs

LB_EN for prune switch rules was causing all TX traffic
to loopback to the internal switch and dropped.  When
running bi-directional stress workloads with RDMA
the RDPU would hang blocking tx and rx traffic.

Don't let the VF know it's not trusted when it tries to add more than
permitted additional MAC addresses.

From: Akeem G Abodunrin <akeem.g.abodunrin@intel.com>

This patch changes how we get VF VSIs instances. Instead of relying on
mailbox virtual channel message to retrieve VSI, it is more reliable
getting it directly via VF object in PF data structure.
