The firmware starts sending nulldata frames for keepalive immediately
after association, regardless of power management state. The driver
thus needs to configure keep alive period unconditionally.

The driver distinguishes between power management and device's power
down enablement. Power management enablement depends both on driver's
module power parameters and mac80211 decision. The device's power down
depends only on driver's module power parameters. Change the driver to
always send Power Table command to enable or disable both power
management and device's power down.

Currently power management is supported only when only a single
virtual interface is present. The driver verifies number of created
interfaces and disables power management when multiple interfaces
present. However, this rule does not extend to a P2P device that is
handled differently in the firmware. If a P2P device is added power
management can remain enabled.

Spin locks and completions are expensive in hard IRQ context and cause
problems with RT kernels.  In RT kernels, both spin locks and
completions can schedule(), so we can't use them in hard irq context.
