Joe Perches b56e681b62 brcmsmac: Remove unnecessary memset casts

Neaten the style by using the sizeof the actual variable

Currently there is a sleep after disconnect on del_station. This
timeout is not needed (anymore) and is causing problems with p2p

del_station and while it waits the 400ms remote side will already

Tim Gardner 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.

Arend van Spriel 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.
