675a0b049a mac80211: Use a cfg80211_chan_def in ieee80211_hw_conf_chan
Drivers that don't use chanctxes cannot perform VHT association because
they still use a "backward compatibility" pair of {ieee80211_channel,
nl80211_channel_type} in ieee80211_conf and ieee80211_local.

39ecc01d1b mac80211: pass queue bitmap to flush operation
There are a number of situations in which mac80211 only
really needs to flush queues for one virtual interface,
and in fact during this frames might be transmitted on
other virtual interfaces. Calculate and pass a queue
bitmap to the driver so it knows which queues to flush.

2880b86859 brcmfmac: use brcmf_if::bssidx as index in interface list
Upon receiving an IF event from the firmware the interface
was created and stored on a list using the interface index.
With upcoming P2P feature the firmware will send a IF event
in which two interfaces have the same interface index. To
uniquely locate them on the list the bss index is now used.

708eb54f20 brcmsmac: fix u16 overflow warning
DOT11_MIN_BEACON_PERIOD and DOT11_MAX_BEACON_PERIOD are
superfluous. The only invalid beacon period is 0. Comparing
a 16 bit quantity to 0xffff also causes a compile warning:

drivers/net/wireless/brcm80211/brcmsmac/main.c:5560 brcms_c_set_beacon_period()
 warn: impossible condition '(period > 65535) => (0-65535 > 65535)'

Observed from smatch analysis.

cbb1ec9491 brcmfmac: fix problem connecting to AP without security
The bcm43236 device showed having an issue connection to an AP without
security when auth_type was set to automatic. For this particular device
a workaround is made by selecting open-system. This problem does not
occur when using wpa_supplicant as it will not use auth type automatic.

Simplify code by using single function for converting channel to
chanspec. No need to set 40MHz flags, as they are not needed for
correct working in FW.
