staging: rtl8188eu: Introduce monitor interface for IEEE 802.11 frames
This adds support for monitoring IEEE 802.11 Data and Management frames
received or transmitted by a RTL8188EU-based device handled by this
driver.
The monitor interface is not enabled by default and will be registered
only if monitor_enable module parameter is set to 1. When enabled it
will show up as a monX network device, which can be used by the
userspace programs for monitoring network traffic.
It is intended as an exploratory/debugging tool for rtl8188eu driver.
