[1/6] mwifiex: parse adhoc start/join result

Commit Message

Amitkumar Karwar Dec. 4, 2015, 2:13 p.m. UTC

Even if ADHOC start or join attempt is failed, these commands
are returned with success status by firmware. Actual connection
result is provided inside command response.

This patch parses the adhoc connection result and resets
connection state variables if connection is not successful.
