Bugzilla: 757944
Brew: <https://brewweb.devel.redhat.com/taskinfo?taskID=5738553>
Upstream Status: 708eb54f20334470ad92042547db0fef0cd60462
Tested: By me. Acceptable. See BZ for details
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.
