The SimpleLink wifi driver enables the Fast Connect method of WiFi provisioning, which allows the network coprocessor to reconnect to a previously connected Access Point (AP) on startup. Previously, if Fast Connect failed to connect, any network socket applications would inevitably fail, as there would have been no wifi connection. This patch adds a configurable timeout for the Fast Connect feature, after which timeout, an error is logged informing the user to manually reconnect to an AP. Reconnection is typically accomplished by separately running the wifi sample shell program. Fixes: #11889 Signed-off-by: Gil Pitney <gil.pitney@linaro.org>
