The local maximum transmit power is the maximum power a wireless device
allowed to transmit. If Power Constraint is presented, the local maximum
power equals to the maximum allowed power defined in regulatory domain
minus power constraint.
The maximum transmit power is maximum power a wireless device capable of
transmitting, and should be used in Power Capability element (7.3.2.16
IEEE802.11 2007).
The transmit power from a wireless device should not greater than the

What might also be useful for any embedded use is to add
CONFIG_RTLWIFI_DEBUG to conditionally remove all of the
debug logging code to reduce the largish object size.
