iwlwifi: mvm: don't send BAID removal to the FW during hw_restart
With the new ML API, we can't send the BAID removal command to
firmware during hw_restart because it will cause an assertion failure
0x350D because the BAID doesn't exist at that point.
So avoid sending the command if we are performing a hw_restart.

iwlwifi: mvm: Consider P2P GO operation during scan
A scan during active P2P GO operation, i.e., data traffic with
clients, can impact the throughput and latency of such traffic.
Thus, when scan is requested while there is an active P2P GO
and low latency is asserted:
- Ask the FW scan logic to respect the P2P GO activity during the
scheduling of the scan operation to minimize the impact on the
throughput and latency.
- Force scan to perform EBS before starting the scan to reduce the

ipv6: remove addrconf reliance on loopback
Second patch in this series removes IPv6 requirement about the netns
loopback device being the last device being dismantled.
This was needed because rt6_uncached_list_flush_dev()
and ip6_dst_ifdown() had to switch dst dev to a known
device (loopback).
Instead of loopback, we can use the (hidden) blackhole_netdev
which is also always there.
This will allow future simplfications of netdev_run_to()
and other parts of the stack like default_device_exit_batch().
Last two patches are optimizations for both IP families.

Add properties `tx-p2p-microvolt` and `tx-p2p-microvolt-names` for this

IPv6 routes. Setting ->rtm_tos for IPv6 is thus invalid as the route
is going to work only on the destination address anyway, so it won't
behave as specified.

Merge branch 'dsa-cleanup'
Vladimir Oltean says:
====================
More aggressive DSA cleanup
This series deletes some code which is apparently not needed.
I've had these patches in my tree for a while, and testing on my boards
didn't reveal any issues.
Compared to the RFC v1 series, the only change is the addition of patch 3.

net: dsa: remove lockdep class for DSA slave address list
Since commit
2f1e8ea726e9 ("net: dsa: link interfaces with the DSA
master to get rid of lockdep warnings"), suggested by Cong Wang, the
DSA interfaces and their master have different dev->nested_level, which
makes netif_addr_lock() stop complaining about potentially recursive
locking on the same lock class.
So we no longer need DSA slave interfaces to have their own lockdep
class.

net: dsa: remove ndo_get_phys_port_name and ndo_get_port_parent_id
There are no legacy ports, DSA registers a devlink instance with ports
unconditionally for all switch drivers. Therefore, delete the old-style
ndo operations used for determining bridge forwarding domains.
