tcp: initialize rcv_tstamp for restored sockets
[ Upstream commit c7781a6e3c4a9a17e144ec2db00ebfea327bd627 ]
u32 rcv_tstamp; /* timestamp of last received ACK */
Its value used in tcp_retransmit_timer, which closes socket
if the last ack was received more then TCP_RTO_MAX ago.
Currently rcv_tstamp is initialized to zero and if tcp_retransmit_timer
is called before receiving a first ack, the connection is closed.
This patch initializes rcv_tstamp to a timestamp, when a socket was
restored.
