The arasan caps registers are no longer being overridden by the brcm iproc
driver, so we should be assuring that the "High Speed Support" bit 21 is set in
the capability register. This significantly improves the wifi perf using linux.

The arasan caps registers are no longer being overridden by
the brcm iproc driver, so we should be assuring that the
"High Speed Support" bit 21 is set in the capability
register. This significantly improves the wifi perf
