Bring scan result handling more in line with drivers like ipw. Scan results are aggregated and a BSS dropped after 15 seconds if no beacon is received. This allows the driver to interact better with userspace where more than one process may request scans or results at any time. Signed-off-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W.
