libertas: remove ps_supported flag, use fwcapinfo
Power save support depends on the firmware capabilities rather than the card's hardware interface. Use the FW_CAPINFO_PS bit in the firmware capabilities mask throughout the driver in place of the redundant ps_supported flag and don't make decisions about PS support in the interface drivers (with the exception of a special case in the USB driver). V2: put the USB special case in the right place. Signed-off-by: Andrey Yurovsky <andrey@cozybit.com> Acked-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
