Currently when we try FT-over-Air, the Authenticate frame is always sent via offchannel infrastructure We request the driver to go offchannel, then send the Authenticate frame. This works fine as long as the target AP is on a different channel. On some networks some (or all) APs might actually be located on the same channel. In this case going offchannel will result in some drivers not actually sending the Authenticate frame until after the offchannel operation completes. Work around this by introducing a new ft_authenticate variant that will not request an offchannel operation first.
