 The manual page says "kernel managed" size. It's hard to tell.
 I think wsize in the context of tcp mounts means window size.
 At least according to what I can read from tcpdump. I will run
 more dumps with various settings and see what I can come up with.
 
 I would not be surprised if the client is doing something that
 deviates from the RFCs. NFSv3 for example is not usable because
 the client zeroes out the nanosecond part of the nfstime3
 attributes, causing attribute mismatches. (We don't have any
 export options that can work around this, do we?)
