cfg80211: Use a structure to pass connect response params

Browse Source 
Currently the connect event from driver takes all the connection
response parameters as arguments. With support for new features these
response parameters can grow. Use a structure to pass these parameters
rather than passing them as function arguments.

* @status: Status code, %WLAN_STATUS_SUCCESS for successful connection, use
* %WLAN_STATUS_UNSPECIFIED_FAILURE if your device cannot give you
* the real status code for failures. If this call is used to report a
* failure due to a timeout (e.g., not receiving an Authentication frame
* from the AP) instead of an explicit rejection by the AP, -1 is used to
* indicate that this is a failure, but without a status code.
* @timeout_reason is used to report the reason for the timeout in that
* case.
* @bssid: The BSSID of the AP (may be %NULL)
* @bss: Entry of bss to which STA got connected to, can be obtained through
* cfg80211_get_bss() (may be %NULL). Only one parameter among @bssid and
* @bss needs to be specified.
* @req_ie: Association request IEs (may be %NULL)
* @req_ie_len: Association request IEs length
* @resp_ie: Association response IEs (may be %NULL)
* @resp_ie_len: Association response IEs length
* @timeout_reason: Reason for connection timeout. This is used when the
* connection fails due to a timeout instead of an explicit rejection from
* the AP. %NL80211_TIMEOUT_UNSPECIFIED is used when the timeout reason is
* not known. This value is used only if @status < 0 to indicate that the
* failure is due to a timeout and not due to explicit rejection by the AP.
* This value is ignored in other cases (@status >= 0).
