85  *			presence of those fields must be indicated to the
86  *			plugin via wd_opts flags.  This allows the drivers
87  *			and the plugin to evolve independently.
88  *
89  *	wd_bssid	Current associated BSSID (or IBSSID), used when
90  *			generating data packet headers for transmission.
91  *
92  *	wd_opmode	Current operation mode; any ieee80211_opmode is
93  *			supported.
94  *
95  *	wd_secalloc	Current allocation policy for security-related
96  *			WiFi headers, used when generating packets for
97  *			transmission.  The plugin will allocate header
98  *		        space for the security portion, and fill in any
99  *			fixed-contents fields.
100  *
101  *	wd_qospad	Generally, QoS data field takes 2 bytes, but
102  *			some special hardwares, such as Atheros, will need the
103  *			802.11 header padded to a 32-bit boundary for 4-address
104  *			and QoS frames, at this time, it's 4 bytes.
