tipc: Prevent loss of fragmented messages over unicast links
Modifies unicast link endpoint logic so an incoming fragmented message is not lost if reassembly cannot begin because there is no buffer big enough to hold the entire reassembled message. The link endpoint now ignores the first fragment completely, which causes the sending node to retransmit the first fragment so that reassembly can be re-attempted. Previously, the sender would have had no reason to retransmit the 1st fragment, so we would never have a chance to re-try the allocation. Signed-off-by: Allan Stephens <allan.stephens@windriver.com>
