--------------------------------+--------------------
 We are testing NFSv4 on a coldfire mcf5329 platform using rtems-6 (MASTER)
 and 6-freebsd-12 (downloaded September 9th).
 The tool chain is bould by rtems-source-builder last version.

 The test program testsuite/nfs01   work correctly but if we try to copy a
 file in a subfolder of NFS disk we meet the issue that I try to describe
 below:


 using telnetd01 example from the testsuite (adding NFS filesytem at
 configuration  with #define CONFIGURE_FILESYSTEM_NFS)  and opening a shell
 we are capable to mount a NFS disk with the command:

 mount -t nfs -o nfsv4,minorversion=1 192.168.3.36:/rtems     /nfs

 (where "192.168.3.36/rtems" is a share from an ubuntu 20.1 machine).


 Mount is fine and we receive the following reply

 "nfs: mount: nfs -> 192.168.3.36:/rtems (nfsv4,minorversion=1)
 nfs: mount args: 8
   16 addr=10 02 08 01 ffffffc0 ffffffa8 03 24 00 00 00 00 00 00 00 00
    0 nfsv4
    7 dirpath=/rtems
    4 fstype=nfs
    4 fspath=nfs
   20 hostname=192.168.3.36:/rtems
    0 rw
    2 minorversion=1
 nfs: mount: (0) Success"

 The issue happen when we try to copy a file in a /nfs subfolder.
 If we create subfolders

 mkdir /nfs/1
 mkdir /nfs/1/2
 mkdir /nfs/1/2/3
 folders are creted correctly but if we try to copy a file as:

 cp xxx /nfs/1/2/3

 unfortunately the file xxx is copied in /nfs/1/2 and NOT  inside
 /nfs/1/2/3 folder.
 The same issue happen in other locations:

 cp xxx /nfs/1/2   file is copied in /nfs/1
 cp xxx /nfs/1     file is copied in /nfs
