Correction from Eric Norum for timeout in TFTP driver following bug

Browse Source 
report by Nick.SIMON@syntegra.bt.co.uk:

TFTP uses UDP and UDP packets are prime targets for getting dropped when
the network gets busy.  I want the number of retries quite large in my
application. I see that PACKET_REPLY_MILLISECONDS is, in fact, not
being used.
