tftp: add timeframe when remote server is retransmitting
If there's packet loss and the remote server needs to retransmit, there is falsely no timeframe left because TIMEOUT (server wait time) and TFTP_TIMEOUT (abort timer) are the same. This patch increases TFTP_TIMEOUT. See RFC2349 for more info: http://tools.ietf.org/html/rfc2349 Signed-off-by: Christoph Fritz <chf.fritz@googlemail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
