Major changes:

wil6210:

* add modparam for bcast ring size
* support hidden SSID
* add per-MCS Rx stats

On some hardware reading WCID entries table results getting 0xff
numbers, no matter of value written there before. This cause assigning
the same WCID for different stations and makes not possible to connect
to more than one station.

We expect EEPROM per-rate power table to be filled with

there appear to be devices which don't have this section
of EEPROM initialized.  In such case we should ignore
the values and leave the driver power tables set to zero.

Note that vendor driver doesn't care about this case but

The watchdog reset as done in brcmf_pcie_buscoreprep() is not
sufficient. It needs to modify PCIe core registers as well
which is properly done by brcmf_pcie_reset_device() after the
chip recognition is done. So the faulty watchdog reset can be
removed as it was causing driver reload to fail and hang the
system requiring a power-cycle. Instead the call to to the
brcmf_pcie_reset_device() function is done twice in the unload.

In the midst of chanctx patch review channel
switching became broken which I failed to notice
until now.

Function ath10k_mac_vif_chan() reports current
chandef which isn't updated until after
switch_vif_chanctx() is returned from.
Consequently the driver just restarted operation
on channels it was residing already instead of
switching to the new ones.

In practice there's no point in having a copy of
chanctx_conf.

Most of the time the channel pointer (and band
along with it) is accessed and this can't change
after a chanctx is created because switching is
done using explicit chanctx swapping via
switch_vif_chanctx().

The only thing that can change within a
chanctx_conf and is used by the driver is
radar_enabled and channel width. These are however
always accessed in adequate mac80211 callback
context which guarantees safe access to the
chanctx data.
