This file contains a set of constants and flags which are already passed
between applications, net_server, and wpa_supplicant to indicate network
security, connection modes, and a variety of other things.
As the OpenBSD net80211 stack does not need wpa_supplicant for WPA2/PSK,
it only makes sense that we would pass the same information we pass
to wpa_supplicant into the stack instead. Rather than expose yet another
set of constants and flags to userland besides the FreeBSD and these
Haiku native ones, just make it so this file can be included in the kernel,
and the constants thus used directly.
