[PATCH 1/2] supplicant: do not change iftype for static AP interface

[Avinash Patil]

Some devices have limitations which do not allow changing virtual interface
mode from AP to station or vice versa. To work around this, check if such
AP interface is not dynamic. If such an interface is enumarated,
just set ifmode to AP & avoid setting nlmode to default station mode.
