In wireless connection, connecting state needs to be cared more
about. ECR 1772 redefined the state EFI_NOT_READY to represent
connecting state and can be retrieved from Aip protocol. This
patch adds a new API to check media state at a specified time
interval when network is connecting until the connection process
finishes or timeout.

My comments as below:
1. "ASSERT (MediaState != NULL)" should be removed since it will be checked later. The same issue is found in NetLibDetectMedia().
2. The Timer event should be created in the first loop for the second loop's check, otherwise, it will be invalid for the next CheckEvent().
do {
//
// Create new Timer
//
CreateEvent ()
SetTimer ();
do {
CheckEvent();
}
CloseEvent (Timer);
Timer = NULL;
}
3. How about changing the default value of *MediaState to EFI_SUCCESS? You know the error status may be returned from API, then the MediaState can't be updated correctly. In such a case, the MediaState should be treated as EFI_SUCCESS.
Or
We might need add the description to comments that the MediaState is only valid when EFI_SUCCESS returned from API.
Thanks,
Jiaxin
