[kvalo@kernel.org: fix mac80211 API changes in start_ap() and stop_ap()]
While reading sysctl_igmp_qrv, it can be changed concurrently.
Thus, we need to add READ_ONCE() to its readers.
This test can be packed into a helper, so such changes will be in the
follow-up series after net is merged into net-next.
qrv ?: READ_ONCE(net->ipv4.sysctl_igmp_qrv);

Using current implementation of polling mode, there is high chances we
will hit into timeout error when running phc2sys. Hence, update the
implementation of hardware crosstimestamping to use the MAC interrupt
service routine instead of polling for TSIS bit in the MAC Timestamp
Interrupt Status register to be set.

Current stmmac driver will prepare/enable ptp_ref clock in
stmmac_init_tstamp_counter().
The stmmac_pltfr_noirq_suspend will disable it once in suspend flow.
But in resume flow,
stmmac_pltfr_noirq_resume --> stmmac_init_tstamp_counter
stmmac_resume --> stmmac_hw_setup --> stmmac_init_ptp --> stmmac_init_tstamp_counter
ptp_ref clock reference counter increases twice, which leads to unbalance
ptp clock when resume back.
Move ptp_ref clock prepare/enable out of stmmac_init_tstamp_counter to fix it.

If netif is running when stmmac_dvr_remove is invoked,
the unregister_netdev will call ndo_stop(stmmac_release) and
vlan_kill_rx_filter(stmmac_vlan_rx_kill_vid).
Currently, stmmac_dvr_remove() will disable pm runtime before
unregister_netdev. When stmmac_vlan_rx_kill_vid is invoked,
pm_runtime_resume_and_get in it returns EACCESS error number,
and reports:

The pm_runtime takes care of the clock handling in current
stmmac drivers, and dwmac-mediatek implement the
mediatek_dwmac_clks_config() as the callback for pm_runtime.
Then, stripping duplicated clocks handling in old init()/exit()
to fix clock issue in suspend/resume test.
As to clocks in probe/remove, vendor need symmetric handling to
ensure clocks balance.
Test pass, including suspend/resume and ko insertion/remove.

Now that we have a pointer to the TX STA even when it's
not authenticated/... yet, fix the TX link selection in
hwsim to select only among the valid links for the STA,

In MLO, we need to transmit to another MLD and select
the link to it, which requires knowing the station.
But in TX, mac80211 will not give us a station that's
not added to the driver, which in the older add/remove
API is only done later.
Implement the new API in MLO so we know about the STA
at all times and get a pointer during TX as well.

1) Support 802.1ad for bridge offloads
Vlad Buslov Says:
=================
Current mlx5 bridge VLAN offload implementation only supports 802.1Q VLAN
Ethernet protocol. That protocol type is assumed by default and
SWITCHDEV_ATTR_ID_BRIDGE_VLAN_PROTOCOL notification is ignored.
In order to support dynamically setting VLAN protocol handle
SWITCHDEV_ATTR_ID_BRIDGE_VLAN_PROTOCOL notification by flushing FDB and
re-creating VLAN modify header actions with a new protocol. Implement support
for 802.1ad protocol by saving the current VLAN protocol to per-bridge variable
and re-create the necessary flow groups according to its current value (either
use cvlan or svlan flow fields).
==================
2) debugfs to count ongoing FW commands
3) debugfs to query eswitch vport firmware diagnostic counters
4) Add missing meter configuration in flow action
