The TNQDR register configures the default QoS settings for NVE
encapsulation.
It will be used to set the default DSCP of each port to 0, so that when
DSCP is set to inherit and the overlay packet does not have an IP header
the outer DSCP will be set to 0, in accordance with the software data
path.

Currently, the seed of the LAG hash function is always set to 0, which
means it is identical across all switches. Instead, use a random number.
This is especially important now that VxLAN is supported, as the LAG
hash function is used to calculate the UDP source port of the
encapsulated packet.

The device has the ability to flush all the FDB records that perform NVE
encapsulation or only a subset of these with a specific filtering
identifier (FID).
Expose these types so that they could be used by subsequent patches
where we need to flush the FDB records when an NVE device is unlinked
from a bridge (FID).

When the device needs to flood an overlay packet to remote VTEPs it
retrieves a pointer to the head of a linked-list of records that store
the IP addresses of these VTEPs.
These records are stored in the KVD linear memory and configured via the
Tunneling NVE Underlay Multicast Table (TNUMT) register.
Add a new KVD linear entry type for these records, so that we will be
able to allocate and free them.

Previous implementation of SAE authentication in infrastructure BSS was
somewhat restricting and not exactly clean way of handling the two
auth() operations. This ended up removing and re-adding the STA entry
for the AP in the middle of authentication and also messing up
authentication state tracking through the sequence of four
Authentication frames. Furthermore, this did not work if the AP ended up
sending out SAE Confirm (auth trans #2) immediately after SAE Commit
(auth trans #1) before the station had time to transmit its SAE Confirm.
Clean up authentication state handling for the SAE case to allow two
rounds of auth() calls without dropping all state between those
operations. Track peer Confirmed status and mark authentication
completed only once both ends have confirmed.
ieee80211_mgd_auth() check for EBUSY cases is now handling only the
pending association (ifmgd->assoc_data) while all pending authentication
(ifmgd->auth_data) cases are allowed to proceed to allow user space to
start a new connection attempt from scratch even if the previously
requested authentication is still waiting completion. This is needed to
avoid making SAE error cases with retries take excessive amount of time
with no means for the user space to stop that (apart from setting the
netdev down).
As an extra bonus, the end of ieee80211_rx_mgmt_auth() can be cleaned up
to avoid the extra copy of the cfg80211_rx_mlme_mgmt() call for ongoing
SAE authentication since the new ieee80211_mark_sta_auth() helper
function can handle both completion of authentication and updates to the
STA entry under the same condition and there is no need to return from
the function between those operations.

This makes it easier to conditionally replace full allocation of
auth_data to use reallocation for the case of continuing SAE
authentication. Furthermore, there was not really any point in having
this check done so late in the function after having already completed

Long/short preamble selection cannot be sampled separately, since it

currently not used preamble modes are not counted in the statistics,

index where necessary.

I'm not really sure exactly _why_ I've been carrying a note
for what's probably _years_ to check that we don't do this,
but we clearly do reflect frames back to the station itself
if it sends such.
One way or the other, it's useless since the station doesn't
really need the AP to talk to itself, so suppress it.
While at it, clarify some of the logic by removing skb->data
references in favour of the destination address (pointer) we
already have separately.

In tipc_sk_filter_rcv(), when we detect protocol messages with error we
call tipc_sk_conn_proto_rcv() and let it reset the connection and notify
the socket by calling sk->sk_state_change().
However, tipc_sk_filter_rcv() may have been called from the function
tipc_backlog_rcv(), in which case the socket lock is held and the socket
already awake. This means that the sk_state_change() call is ignored and
the error notification lost. Now the receive queue will remain empty and
the socket sleeps forever.
In this commit, we convert the protocol message into a connection abort
message and enqueue it into the socket's receive queue. By this addition
to the above state change we cover all conditions.

The order in which we release resources is unfortunately leading to bus
errors while dismantling the port. This is because we set
priv->wol_ports_mask to 0 to tell bcm_sf2_sw_suspend() that it is now
permissible to clock gate the switch. Later on, when dsa_slave_destroy()
comes in from dsa_unregister_switch() and calls
dsa_switch_ops::port_disable, we perform the same dismantling again, and
this time we hit registers that are clock gated.
Make sure that dsa_unregister_switch() is the first thing that happens,
which takes care of releasing all user visible resources, then proceed
with clock gating hardware. We still need to set priv->wol_ports_mask to
0 to make sure that an enabled port properly gets disabled in case it
was previously used as part of Wake-on-LAN.
