loader: tftp: Don't let tftp timeout
When we load a kernel or module we open/close it a few times. Since we're using the same port number each time and that we requested the same file the ACK that we send are valid on the server side and the server send us the file multiple times. This makes tftp loading time very inconsistant due to the UDP "flood" that we have to process. Reviewed by: imp, tsoome MFC after: 2 weeks Sponsored by: Beckhoff Automation GmbH & Co.
