Looks like tsize negotiation - it looks as though the client sends tsize 0
with the RRQ, then our opcode 6(?) offers a large tsize which client
responds to with an error, then the client sends a RRQ with tsize 0, blksize
1420, and the server replies with opcode 6 blksize 1420 and the same large
tsize as before. Block number is bound to roll over in this particular
large file case...
